Spectroscopic evidence of disorder-induced quantum phase transitions in monolayer Fe(Te,Se) superconductor
Guanyang He, Ziqiao Wang, Longxin Pan +5
The superconductor-insulator transition as a paradigm of quantum phase transitions has attracted tremendous interest over the past three decades. While the magnetic field and carri…
Evolution from Landau Quantization to Discrete Scale Invariance Revealed by Quantum Oscillations in Topological Materials
Jiayi Yang, Nannan Tang, Yunxing Li +10
Dirac materials have been a unique solid state platform for exploring relativistic quantum phenomena including supercritical atomic collapse, which leads to emergent discrete scale…
Exceedingly large in-plane critical field of finite-momentum pairing state in bulk superlattices
Junfa Lin, Ziqiao Wang, Hongyi Yan +15
Magnetic flux profoundly influences the phase factor of charge particles, leading to exotic quantum phenomena. A recent example is that the orbital effect of magnetic field could i…
High-temperature field-free superconducting diode effect in high-Tc cuprates
Shichao Qi, Jun Ge, Chengcheng Ji +7
The superconducting diode effect (SDE) is defined by the difference in the magnitude of critical currents applied in opposite directions. It has been observed in various supercondu…
Quantum Griffiths singularity in a three-dimensional superconductor to Anderson critical insulator transition
Shichao Qi, Yi Liu, Ziqiao Wang +11
Disorder is ubiquitous in real materials and can have dramatic effects on quantum phase transitions. Originating from the disorder enhanced quantum fluctuation, quantum Griffiths s…
