Superconducting Decoherence and Thermal Quenching of the Josephson Diode Effect in Low-Dimensional Josephson Systems
F. Yang, C. Y. Dong, Joshua A. Robinson +1
Motivated by recent studies on superconducting (SC) diode nonreciprocity, we uncover a generic smooth SC-phase decoherence mechanism in low-dimensional Josephson structures. Contra…
Engineering the non-Hermitian Su-Schrieffer-Heeger model with skin effects in Rydberg atom arrays
J. N. Bai, F. Yang, D. Yan +2
We propose and systematically analyze a practical scheme for implementing a one-dimensional non-Hermitian (NH) Su-Schrieffer-Heeger model using individually addressable Rydberg ato…
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…
A tractable framework for phase transitions in phase-fluctuating disordered 2D superconductors: applications to bilayer MoS and disordered InO thin films
F. Yang, L. Q. Chen
Starting from the purely microscopic model, we go beyond conventional mean-field theory and develop a self-consistent microscopic thermodynamic framework for disordered 2D supercon…
Preformed Cooper pairing and the uncondensed normal-state component in phase-fluctuating monolayer cuprate superconductivity
F. Yang, Y. Shi, L. Q. Chen
We develop a self-consistent microscopic framework beyond mean-field theory for monolayer cuprate superconductivity. It couples fermionic quasiparticles with collective phase dynam…
Microscopic Phase-Transition Framework for Gate-Tunable Superconductivity in Monolayer WTe
F. Yang, G. D. Zhao, Y. Shi +1
The recently reported gate-tunable superconductivity in monolayer WTe [Science 362, 922 (2018); Science 362, 926 (2018); Nat. Phys. 20, 269 (2024); PRR 7, 013224 (2025)] exhibi…
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…
Correlation-Driven -Wave Superconducting Dome from Pseudogap Spectral Reconstruction
Yue Yuan, Ziwen Pan, F. Yang
Previous theoretical studies [Nat. Phys. {\bf 16}, 1175 (2020)] based on the Hatsugai-Kohmoto model have examined the stability of -wave superconductivity in strongly correlated…
Microscopic phase-transition theory of charge density waves: revealing hidden crossovers of phason and amplitudon
F. Yang, L. Q. Chen
We develop a self-consistent phase-transition theory of charge density waves (CDWs), starting from a purely microscopic model. Specifically, we derive a microscopic CDW gap equatio…
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…
