Ferroelectric Order and Enhanced Interfacial Superconductivity in Lightly-Doped Quantum Paraelectric KTaNbO
F. Yang, L. Q. Chen
Ferroelectric quantum criticality in perovskite oxides offers a fertile ground for emergent collective phenomena. Here we develop a first-principles-inspired quantum-statistics-bas…
Altermagnetism-induced non-collinear superconducting diode effect and unidirectional superconducting transport
F. Yang, L. Q. Chen
Current studies of non-reciprocal superconducting (SC) transport have centered on the forward-backward asymmetry of the critical current measured along a single axis. In most reali…
Revealing THz optical signatures of Shiba-state-induced gapped and gapless superconductivity
F. Yang, R. Y. Fang, S. L. Zhang +1
We report a fully self-consistent calculation of the complex renormalization by exchange interactions and hence the complete phase diagram of conventional -wave superconductors…
Spin relaxation and transport behaviors in altermagnetic systems
Y. J. Sun, F. Yang, L. Q. Chen
The D'yakonov-Perel' (DP) spin-relaxation mechanism has traditionally been associated with either relativistic spin-orbit coupling, which breaks space-inversion symmetry, or inhomo…
Role of Ferrons in the Heat Capacity and Thermal Transport of Displacive Ferroelectrics
G. D. Zhao, F. Yang, L. Q. Chen
The collective amplitude mode of the order parameter in displacive ferroelectrics, termed the ferron, represents the amplitude fluctuations of long-range ordered polarization. At t…
Terahertz-induced second-harmonic generation in quantum paraelectrics: hot-phonon effect
F. Yang, X. J. Li, D. Talbayev +1
Recent terahertz-pump second-harmonic-generation(SHG)-probe measurements of quantum paraelectrics observed a significant long-lived non-oscillatory SHG component following an ultra…
