Angle-resolved photoemission studies of quantum materials

JA Sobota, Y He, ZX Shen - Reviews of Modern Physics, 2021 - APS
The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Stranger than metals

PW Phillips, NE Hussey, P Abbamonte - Science, 2022 - science.org
In traditional metals, the temperature (T) dependence of electrical resistivity vanishes at low
or high T, albeit for different reasons. Here, we review a class of materials, known as …

A Jindal, A Saha, Z Li, T Taniguchi, K Watanabe… - Nature, 2023 - nature.com
Achieving electrostatic control of quantum phases is at the frontier of condensed matter
research. Recent investigations have revealed superconductivity tunable by electrostatic …

Exploration of doped quantum magnets with ultracold atoms

A Bohrdt, L Homeier, C Reinmoser, E Demler, F Grusdt - Annals of Physics, 2021 - Elsevier
In the last decade, quantum simulators, and in particular cold atoms in optical lattices, have
emerged as a valuable tool to study strongly correlated quantum matter. These experiments …

Incoherent transport across the strange-metal regime of overdoped cuprates

J Ayres, M Berben, M Čulo, YT Hsu, E van Heumen… - Nature, 2021 - nature.com
Strange metals possess highly unconventional electrical properties, such as a linear-in-
temperature resistivity,,,,–, an inverse Hall angle that varies as temperature squared,–and a …

Topological Mott insulator at quarter filling in the interacting Haldane model

P Mai, BE Feldman, PW Phillips - Physical Review Research, 2023 - APS
While the recent advances in topology have led to a classification scheme for electronic
bands described by the standard theory of metals, a similar scheme has not emerged for …

Universal correlation between H-linear magnetoresistance and T-linear resistivity in high-temperature superconductors

J Ayres, M Berben, C Duffy, RDH Hinlopen… - Nature …, 2024 - nature.com
The signature feature of the 'strange metal'state of high-T c cuprates—its linear-in-
temperature resistivity—has a coefficient α 1 that correlates with T c, as expected were α 1 …

Solvable models of two-level systems coupled to itinerant electrons: Robust non-Fermi liquid and quantum critical pairing

E Tulipman, N Bashan, J Schmalian, E Berg - Physical Review B, 2024 - APS
Strange metal behavior is traditionally associated with an underlying putative quantum
critical point at zero temperature. However, in many correlated metals, eg, high-T c cuprate …

Tunable non-Fermi liquid phase from coupling to two-level systems

N Bashan, E Tulipman, J Schmalian, E Berg - Physical Review Letters, 2024 - APS
We study a controlled large-N theory of electrons coupled to dynamical two-level systems
(TLSs) via spatially random interactions. Such a physical situation arises when electrons …

Strongly overdoped : Evidence for Josephson-coupled grains of strongly correlated superconductor

Y Li, A Sapkota, PM Lozano, Z Du, H Li, Z Wu… - Physical Review B, 2022 - APS
The interpretation of how superconductivity disappears in cuprates at large hole doping has
been controversial. To address this issue, we present an experimental study of single-crystal …
