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…
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…
Nanoscale electrothermal-switch superconducting diode for electrically programmable superconducting circuits
Tianyu Li, Jiong Li, Chong Li +13
Superconducting diodes enable dissipationless directional transport, yet achieving electrical tunability and scalability remains a major challenge for circuit-level integration. He…
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…

Jun-Ling Wang, Jiong Li, Qing-Hu Chen
The dissipative phase transitions in the open transverse and longitudinal Dicke-Ising model (DIM), which incorporates nearest-neighbor Ising-type spin interactions into the Dicke f…
-symmetric two-photon quantum Rabi models
Yi-Cheng Wang, Jiong Li, Qing-Hu Chen
We investigate two non-Hermitian two-photon quantum Rabi models (tpQRM) that exhibit symmetry: the biased tpQRM (btpQRM), in which the qubit bias is purely imaginary…

Vacuum Rabi Splitting and Quantum Fisher Information of a Non-Hermitian Qubit in a Single-Mode Cavity
Yi-Cheng Wang, Jiong Li, Li-Wei Duan +1
A natural extension of the non-Hermitian qubit is to place it in a single-mode cavity. This setup corresponds to the quantum Rabi model (QRM) with a purely imaginary bias on the qu…
