Geometric Superconducting Diode Effect in an NbN Nanoring
Tianyu Li, Peiyuan Huang, Jiong Li +14
Superconducting diodes, which exhibit nonreciprocal critical currents, are promising building blocks for low-power cryogenic electronics and superconducting circuits. Existing supe…
Non-Hermiticity of an anomalous superradiant phase
Jun-Ling Wang, You-Qi Lu, Qing-Hu Chen +1
We counterintuitively present a Hermitian squeezing-Dicke model as a minimal setting for non-Hermitian physics in many-body light-matter systems. It enables the realization of a no…
Quantum Criticality from Spectral Collapse in the Two-Photon Rabi Model
Jiong Li, Jun-Ling Wang, Jun-ling Wang +2
Spectral collapse in the two-photon quantum Rabi model (tpQRM) has long been regarded as insufficient to establish quantum criticality because, under generic conditions, the lowest…
Vortex-driven superconducting diode effect in asymmetric multilayer heterostructures
Jiong Li, Ji Jiang, Qing-Hu Chen
The superconducting diode effect (SDE), characterized by nonreciprocal critical currents, has attracted growing attention due to its potential applications in quantum technologies…
Superradiant phase transitions in the quantum Rabi model: Overcoming the no-go theorem through anisotropy
Tian Ye, Yan-Zhi Wang, Xiang-You Chen +2
Although the superradiant phase transition (SRPT) is prohibited in the paradigmatic quantum Rabi model due to the no-go theorem caused by the term, we demonstrate tw…
Phase Transitions in the Anisotropic Dicke-Stark Model with -square terms
Xiang-You Chen, Yu-Yu Zhang, Qing-Hu Chen +1
The superradiant phase transition (SRPT) is forbidden in the standard isotropic Dicke model due to the so-called no-go theorem induced by A-square term. In the framework of the Dic…
