Time-reversal symmetry breaking superconductivity in the presence of loop-current fluctuations
Zenghui Fan, Runyu Ma, Stefano Chesi +2
Loop currents have been proposed in various superconductors and recently confirmed in kagome materials, raising a fundamental question regarding their intrinsic connection to super…
Quantum phase transitions of the anisotropic Dicke-Ising model in driven Rydberg arrays
Bao-Yun Dong, Ying Liang, Stefano Chesi +1
We study the properties of a generalized Dicke-Ising model realized with an array of Rydberg atoms, driven by microwave electric fields and coupled to an optical cavity. As this pl…
Universal Entanglement Revival of Topological Origin
Dongni Chen, Stefano Chesi, Mahn-Soo Choi
We have analyzed the dynamics of entanglement in dissipative fermionic and bosonic Su-Schrieffer-Heeger (SSH) models and found that, when the decoherence channel preserves the chir…
Quantum and Semi-Classical Signatures of Dissipative Chaos in the Steady State
Griffith Rufo, Sabrina Rufo, Pedro Ribeiro +1
We investigate the quantum-classical correspondence in open quantum many-body systems using the SU(3) Bose-Hubbard trimer as a minimal model. Combining exact diagonalization with s…
