Bipolaronic superconductivity out of a Coulomb gas
J. Sous, C. Zhang, M. Berciu +4
Employing unbiased sign-problem-free quantum Monte Carlo, we investigate the effects of long-range Coulomb forces on BEC of bipolarons using a model of bond phonon-modulated electr…
The Generalized Green's function Cluster Expansion: A Python package for simulating polarons
Matthew R. Carbone, Stepan Fomichev, Andrew J. Millis +3
We present an efficient implementation of the Generalized Green's function Cluster Expansion (GGCE), which is a new method for computing the ground-state properties and dynamics of…
Absence of a BCS-BEC crossover in the cuprate superconductors
John Sous, Yu He, Steven A. Kivelson
We examine key aspects of the theory of the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensation (BEC) crossover, focusing on the temperature dependence of the chemical po…
Unidirectional subsystem symmetry in a hole-doped honeycomb-lattice Ising magnet
Sambuddha Sanyal, Alexander Wietek, John Sous
We study a model of a hole-doped collinear Ising antiferromagnet on the honeycomb lattice as a route toward the realization of subsystem symmetry. We find nearly exact conservation…
The normal state of attractive Fermi gases from coupled-cluster theory
James M. Callahan, John Sous, Timothy C. Berkelbach
We introduce coupled-cluster (CC) theory for the numerical study of the normal state of two-component, dilute Fermi gases with attractive, short-range interactions at zero temperat…
Bipolaronic high-temperature superconductivity
C. Zhang, J. Sous, D. R. Reichman +4
Electron-lattice interactions play a prominent role in quantum materials, making a deeper understanding of direct routes to phonon-mediated high-transition-temperature ($T_{\mathrm…
