  2. Surprising discovery uncovers new type of 'strange metal'

    Scientists understand quite well how temperature affects electrical conductance in everyday metals like copper or silver. But in recent years, researchers have turned their attention to a class of materials that do not seem to follow the traditional electrical rules. Understanding these so-called 'strange metals' could provide fundamental insights into the quantum world, and potentially help scientists understand strange phenomena like high-temperature superconductivity.

    Now, a research team co-led by a physicist at Brown University has added a new discovery to the strange metal mix. In a paper in Nature, the team report finding strange metal behavior in a material where electrical charge is carried not by electrons but by more 'wave-like' entities called Cooper pairs.

    While electrons belong to a class of particles called fermions, Cooper pairs act as bosons, which follow very different rules from fermions. This is the first time that strange metal behavior has been seen in a bosonic system, and the researchers are hopeful that their discovery might prove helpful in finding an explanation for how strange metals work – something that has eluded scientists for decades.

    “We have these two fundamentally different types of particles whose behaviors converge around a mystery,” said Jim Valles, a professor of physics at Brown and the paper’s corresponding author. “What this says is that any theory to explain strange metal behavior can’t be specific to either type of particle. It needs to be more fundamental than that.”

    Strange metal behavior was first discovered around 30 years ago in a class of materials called cuprates. These copper-oxide materials are most famous for being high-temperature superconductors, meaning they conduct electricity with zero resistance at temperatures far above that of normal superconductors. But even at temperatures above the critical temperature for superconductivity, cuprates act strangely compared to other metals.

    As their temperature increases, cuprates’ resistance increases in a strictly linear fashion. In normal metals, the resistance increases only so far, becoming constant at high temperatures in accord with what's known as Fermi liquid theory. Resistance arises when electrons flowing in a metal bang into the metal’s vibrating atomic structure, causing them to scatter. Fermi-liquid theory sets a maximum rate at which electron scattering can occur.

    But strange metals don’t follow the Fermi-liquid rules, and no one is quite sure how they work. What scientists do know is that the temperature-resistance relationship in strange metals appears to be related to two fundamental constants of nature: Boltzmann’s constant, which represents the energy produced by random thermal motion, and Planck’s constant, which relates to the energy of a photon (a particle of light).

    “To try to understand what’s happening in these strange metals, people have applied mathematical approaches similar to those used to understand black holes,” Valles said. “So there’s some very fundamental physics happening in these materials.”

    In recent years, Valles and his colleagues have been studying electrical activity where the charge carriers are not electrons. In 1952, Nobel Laureate Leon Cooper, now a Brown professor emeritus of physics, discovered that in normal superconductors (not the high-temperature kind discovered later), electrons team up to form Cooper pairs, which can glide through an atomic lattice with no resistance. Despite being formed by two electrons, which are fermions, Cooper pairs can act as bosons.

    “Fermion and boson systems usually behave very differently,” Valles said. “Unlike individual fermions, bosons are allowed to share the same quantum state, which means they can move collectively like water molecules in the ripples of a wave.”

    In 2019, Valles and his colleagues showed that Cooper pair bosons can produce metallic behavior, meaning they can conduct electricity with some amount of resistance. That in itself was a surprising finding, the researchers say, because elements of quantum theory suggested that the phenomenon shouldn’t be possible. For this latest research, the team wanted to see if bosonic Cooper-pair metals were also strange metals.

    The team used a cuprate material called yttrium barium copper oxide patterned with tiny holes that induce the Cooper-pair metallic state. The team cooled this material down to just above its superconducting temperature to observe changes in its conductance. They found, like fermionic strange metals, a Cooper-pair metal conductance that is linear with temperature.

    The researchers say this new discovery will give theorists something new to chew on as they try to understand strange metal behavior.

    “It’s been a challenge for theoreticians to come up with an explanation for what we see in strange metals,” Valles said. “Our work shows that if you’re going to model charge transport in strange metals, that model must apply to both fermions and bosons — even though these types of particles follow fundamentally different rules.”

    Ultimately, a theory of strange metals could have massive implications. Strange metal behavior could hold the key to understanding high-temperature superconductivity, which has vast potential for things like lossless power grids and quantum computers. And because strange metal behavior seems to be related to fundamental constants of the universe, understanding this behavior could shed light on basic truths of how the physical world works.

    While plenty of structures with low symmetry are found in nature, scientists have been confined to high-symmetry designs when synthesizing colloidal crystals, a valuable type of nanomaterial used for chemical and biological sensing and optoelectronic devices. Now, a research team from Northwestern University and the University of Michigan has drawn back the curtain, showing for the first time how low-symmetry colloidal crystals can be made – including one crystal phase for which there is no known natural equivalent.

    “We’ve discovered something fundamental about the system for making new materials,” said Northwestern's Chad Mirkin. “This strategy for breaking symmetry rewrites the rules for material design and synthesis.”

    Mirkin is a professor of chemistry in the Weinberg College of Arts and Sciences; a professor of chemical and biological engineering, biomedical engineering, and materials science and engineering at the McCormick School of Engineering; and a professor of medicine at the Feinberg School of Medicine. He also is the founding director of the International Institute for Nanotechnology.

    The research was directed by Mirkin and Sharon Glotzer, chair of chemical engineering at the University of Michigan. The research team reports its findings in a paper in Nature Materials.

    Nanoparticles can be programmed and assembled into ordered arrays known as colloidal crystals, which can be engineered for applications ranging from light sensors and lasers to communications and computing. “Using large and small nanoparticles, where the smaller ones move around like electrons in a crystal of metal atoms, is a whole new approach to building complex colloidal crystal structures,” said Glotzer.

    In this study, metal nanoparticles whose surfaces were coated with designer DNA were used to create the crystals. The DNA acted as an encodable bonding material, transforming the nanoparticles into what are called programmable atom equivalents (PAEs). This approach offers exceptional control over the shape and parameters of the crystal lattices, as the nanoparticles can be ‘programmed’ to arrange themselves in specified ways, following a set of rules previously developed by Mirkin and his colleagues.

    Up to now, however, scientists have not had a way to prepare lattices with certain crystal symmetries. Because many PAEs are isotropic – meaning their structures are uniform in all directions – they tend to arrange themselves into highly symmetric assemblies, and it is difficult to create low-symmetry lattices. This has limited the kinds of structures that can be synthesized, and therefore the optical properties that can be realized with them.

    The breakthrough came through a new approach to controlling valency. In chemistry, valency is related to the arrangement of electrons around an atom. It determines the number of bonds the atom can form and the geometry it assumes. Building on a recent discovery that small PAEs can behave as electron equivalents, roaming through and stabilizing lattices of larger PAEs, the Northwestern and Michigan researchers altered the valency of their electron equivalents by adjusting the density of the strands of DNA grafted to their surfaces.

    Next, they used advanced electron microscopy to observe how changing the valency of the electron equivalents affected their spatial distribution among the PAEs and therefore the resulting lattices. They also examined the effects of changing the temperature and altering the ratio of PAEs to electron equivalents.

    "We explored more complex structures where control over the number of neighbors around each particle produced further symmetry breaking,” said Glotzer. “Our computer simulations helped to decipher the complicated patterns and reveal the mechanisms that enabled the nanoparticles to create them.”

    This approach set the stage for the creation of three new, never-before synthesized crystalline phases. One, a triple double-gyroid structure, has no known natural equivalent.

    These low-symmetry colloidal crystals have optical properties that can’t be achieved with other crystal structures and may find use in a wide range of technologies. Their catalytic properties are different as well. But the new structures unveiled in this study are only the beginning of the possibilities now that the conditions for breaking symmetry are understood.

    “We’re in the midst of an unprecedented era of materials synthesis and discovery,” said Mirkin. “This is another step forward in bringing new, unexplored materials out of the sketchbook and into applications that can take advantage of their rare and unusual properties.”

    Special issue information:

    Nanotechnology has made it possible for us to create materials that we could never do before by taking advantages of the size effects and the surface effects. A nanomaterial may have different behaviors compared to the same substance in bulk form. That means that a material could change when it goes from bulk to nanoscale and this change could bring a revolution in the world. Nanomaterials have been used for many different things including our foods, our clothes, our lights, our building materials, our medicine and so on. Nanomaterials are, not just something made in a laboratory but they are also found in nature. In ash clouds from volcanoes, sea breeze and in the smoke from a fire, for example.
    Nanomedicine is the application of nanotechnology to the field of medicine by the use of nanomaterials. The most common application of nanomedicine involves employing nanoparticles to enhance the action of drugs in the treatment of cancer and diabetes as examples. Many current applications of nanomedicine are enforcing drug delivery for therapy for cancer targeting for precise diagnosis and treatment.

    Even the research in nanomaterials and nanomedicine has made a great progress, there is still a big gap between the basic research in the laboratory and the practical applications. In this special issue, we will focus on the challenging issues of nanomaterials for practical applications, and particularly for medical applications.
