Emergent magnetic nonanalyticity in Dirac altermagnets
Xizhi Fu, Zhenqiao Huang, Fei Yang +3
Symmetry has long provided the organizing principle for understanding how materials respond to external perturbations. Here we show that what is permitted by symmetry need not be w…
Collective phase modes in twisted -wave superconducting bilayers
Yin Shi, Mengxian Zhao, Fei Yang +2
Twisted cuprate bilayers have been predicted to host high-temperature chiral superconductivity, originating from higher-order Josephson coupling processes. In such two-dime…
Quench of chiral superconductivity by quantum phase fluctuations in twisted cuprate bilayers
Yin Shi, Mengxian Zhao, Fei Yang +2
Following theoretical proposals of chiral superconductivity in twisted cuprate bilayers, experimental signatures of time-reversal symmetry breaking (TRSB) remain highly con…
Excitonic-Superconducting Coexistence and Emergent Nematic Superconductivity Driven by Spontaneous Symmetry Breaking
Fei Yang, Ruigang Li, Junwei Liu +1
Excitonic insulating (EI) and superconducting (SC) orders are generally regarded as mutually exclusive electronic instabilities. Within a self-consistent microscopic theory, we stu…
Tracking unconventional superconductivity in the presence of strongly correlated Fermi arcs
Xianliang Zhou, Fei Yang, Miao Liu +2
One of the primary reasons that superconductivity in underdoped cuprates is enigmatic is that it emerges from an incoherent Fermi-arc state, so the applicability of the Bardeen-Coo…
Dephasing-induced Quantum Hall Criticality in the Quantum Anomalous Hall system
Fei Yang, Dong E. Liu
Conventional wisdom holds that static disorder is indispensable to the integer quantum Hall effect, underpinning both quantized plateaus and the plateau-plateau transition. We show…
Dissecting coupled orders in a terahertz-driven electron-doped cuprate
Liwen Feng, Haotian Zhang, Tim Priessnitz +16
The interplay between superconductivity and charge density wave has often been studied from an equilibrium point of view. For example, using static tuning knobs such as doping, mag…
Non-Hermitian Chiral Edge Modes With Complex Fermi Velocity
Fei Yang, Xue-Ping Ren, Su-peng Kou
Recently, much attention has been paid to uncovering the influence of dissipation on a quantum system, particularly on how the non-Hermitian (NH) terms modify the band topology of…
Optical response of Higgs mode in superconductors at clean limit: formulation through Eilenberger equation and Ginzburg-Landau Lagrangian
F. Yang, M. W. Wu
Both macroscopic Ginzburg-Landau Lagrangian and microscopic gauge-invariant kinetic equation suggest a finite Higgs-mode generation in the second-order optical response of supercon…
Symmetry classes of dissipative topological insulators with edge dark state
Fei Yang, Zheng Wei, Xianqi Tong +2
We classify the dissipative topological insulators (TIs) with edge dark states (EDS) by using the 38-fold way of non-Hermitian systems in this paper. The dissipative dynamics of th…
Quantum anomalous Hall effect in atomic crystal layers from in-plane magnetization
Yafei Ren, Junjie Zeng, Xinzhou Deng +3
We theoretically report that, with \textit{in-plane} magnetization, the quantum anomalous Hall effect (QAHE) can be realized in two-dimensional atomic crystal layers with preserved…
