Revealing Hidden Unconventional Pairing through Nonreciprocal Transport
Wen-Bo Dai, Ming Gong, Xianxin Wu +2
Identifying the pairing symmetry of Cooper pairs is a fundamental step toward understanding the microscopic mechanisms of unconventional superconductors. However, experimental iden…
Logarithmic Aging Diffusion from a Multiplicative Event Clock: Rare Event Statistics, Ultraslow Transport, and Ensemble-Time Inequivalence
Chunyan Li, Zheng Li, Yueyan Li +2
Logarithmic time dependences occur in many aging materials, but neither a relaxation law nor a event rate uniquely identifies the underlying stochastic mechanism. We…
First-Order PT Phase Transition in Non-Hermitian Superconductors
Xuezhu Liu, Ming Lu, Haiwen Liu +1
The interplay between superconductivity and environmental dissipation, effectively captured by non-Hermitian Hamiltonian, is a new frontier for exotic quantum phases. We explore a…
Non-Hermitian superconducting diode effect
Junjie Qi, Ming Lu, Jie Liu +2
The study of non-reciprocal phenomena has long captivated interest in both Hermitian and non-Hermitian systems. The superconducting diode effect (SDE) is a non-reciprocal phenomeno…
Rare-Event-Induced Ergodicity Breaking in Logarithmic Aging Systems
Chunyan Li, Qingyang Feng, Tianjie Zhou +2
Ergodicity breaking and aging effects are fundamental challenges in out-of-equilibrium systems. Various mechanisms have been proposed to understand the non-ergodic and aging phenom…
Edge supercurrent in Josephson junctions based on topological materials
Junjie Qi, Chui-Zhen Chen, Juntao Song +4
The interplay between novel topological states and superconductivity has garnered substantial interest due to its potential for topological quantum computing. The Josephson effect…
