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…
Correlation between unconventional superconductivity and strange metallicity revealed by operando superfluid density measurements
Ruozhou Zhang, Mingyang Qin, Chenyuan Li +15
Strange-metal behavior has been observed in superconductors ranging from cuprates to pressurized nickelates, but its relationship to unconventional superconductivity remains elusiv…
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…
Superconductivity of non-Fermi liquids described by Sachdev-Ye-Kitaev models
Chenyuan Li, Subir Sachdev, Darshan G. Joshi
We investigate models of electrons in the Sachdev-Ye-Kitaev class with random and all-to-all electron hopping, electron spin exchange, and Cooper-pair hopping. An attractive on-sit…
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…
Topological spin excitations observed in a three-dimensional antiferromagnet
Weiliang Yao, Chenyuan Li, Lichen Wang +7
Band topology, or global wave-function structure that enforces novel properties in the bulk and on the surface of crystalline materials, is currently under intense investigations f…
Dirac and nodal line magnons in three-dimensional antiferromagnets
Kangkang Li, Chenyuan Li, Jiangping Hu +2
We study the topological properties of magnon excitations in three-dimensional antiferromagnets, where the ground state configuration is invariant under time-reversal followed by s…
