DOI: 10.1016/j.aop.2020.168138
Abstract: We develop a theory of quantum $T = 0$ phase transition (q-SMT) between metal and superconducting ground states in a two-dimensional metal with frozen-in spatial fluctuations $\delta\lambda(r)$ of the Cooper attraction constant. When strength of… read more here.

DOI: 10.1038/s41586-020-2052-z
Abstract: A wide range of metals exhibit anomalous electrical and thermodynamic properties when tuned to a quantum critical point (QCP), although the origins of such strange metals have posed a long-standing mystery. The frequent association of… read more here.

DOI: 10.1073/pnas.2116980119
Abstract: Significance The elusive strange metal phase (ground state) was observed in a variety of quantum materials, notably in f-electron–based rare-earth intermetallic compounds. Its emergence has remained unclear. Here, we propose a generic mechanism for this… read more here.

DOI: 10.1073/pnas.2206921119
Abstract: Significance The strange metal state of the cuprate superconductors is the parent state from which many novel quantum phases emerge. Experiments have shown that the strange metal extends over a wider range of electron densities… read more here.

DOI: 10.1103/physrevb.98.165135
Abstract: We study a dual flavor fermion model where each of the flavors form a Sachdev-Ye-Kitaev (SYK) system with arbitrary and possibly distinct $q$-body interactions. The crucial new element is an arbitrary all-to-all $r$-body interaction between… read more here.

DOI: 10.1126/science.366.6469.1090-b
Abstract: Superconductivity Many physicists working on cuprate superconductors believe that the so-called strange metal phase in the cuprate phase diagram is associated with a quantum critical point. Within this picture, the quantum critical point gives rise… read more here.

DOI: 10.1126/science.abc4787
Abstract: Understanding the strange metallic behavior that develops at the brink of localization in quantum materials requires probing the underlying electronic charge dynamics. Using synchrotron radiation–based Mössbauer spectroscopy, we studied the charge fluctuations of the strange… read more here.
