Entanglement entropy of fermions in a strange metal
Santanu Singh, Surajit Bera, Chenyuan Li +2
The subsystem-size dependence of ground-state entanglement entropy and its crossover to thermal entropy as a function of temperature are well understood for one-dimensional (1D) ga…
Strange metal and superconductor in the two-dimensional Yukawa-Sachdev-Ye-Kitaev model
Chenyuan Li, Davide Valentinis, Aavishkar A. Patel +4
The two-dimensional Yukawa-Sachdev-Ye-Kitaev (2d-YSYK) model provides a universal theory of quantum phase transitions in metals in the presence of quenched random spatial fluctuati…
Critical anomalous metals near superconductivity in models with random interactions
Chenyuan Li, Darshan G. Joshi, Subir Sachdev
Anomalous metals are observed in numerous experiments on disordered two-dimensional systems proximate to superconductivity. A characteristic feature of an anomalous metal is that i…
Metal-insulator transition in a random Hubbard model
Grigory Tarnopolsky, Chenyuan Li, Darshan G. Joshi +1
We examine the metal-insulator transition in a half-filled Hubbard model of electrons with random and all-to-all hopping and exchange, and an on-site non-random repulsion, the Hubb…
Deconfined critical point in a doped random quantum Heisenberg magnet
Darshan G. Joshi, Chenyuan Li, Grigory Tarnopolsky +2
We describe the phase diagram of electrons on a fully connected lattice with random hopping, subject to a random Heisenberg spin exchange interactions between any pair of sites and…
