Bimodule duality and Artin's problem for skew field extensions
Niels Lauritzen, Jesper Funch Thomsen
Emil Artin asked whether the left and right dimensions of an extension of skew fields must agree. Cohn and Schofield gave counterexamples through elaborate constructions. It has be…
Decoding Equilibrium and Dynamical Criticality in the 2D Topological Order
Xiao-Ming Zhao, Cui-Xian Guo, Gaoyong Sun +1
Analytically connecting equilibrium criticality and dynamical quantum phase transitions (DQPTs) under complex driving fields remains a significant challenge, primarily due to the c…
Tailoring Corner States and Exceptional Points in Altermagnets
Xiao-Ming Zhao, Cui-Xian Guo, Xin-Ran Ma +2
Altermagnets (AMs) exhibit vanishing net magnetization but strong momentum-dependent spin splitting enforced by crystal symmetry. Here, we explore the non-Hermitian effects in diss…
Anomalous non-Hermitian skin effect: the topological inequivalence of skin modes versus point gap
Gang-Feng Guo, Xi-Xi Bao, Han-Jie Zhu +4
Non-Hermitian skin effect, the localization of an extensive number of eigenstates at the ends of the system, has greatly expanded the frontier of physical laws. It has long been be…
Emergent Quasiperiodicity from Polariton-phonon Hybrid Excitations in Waveguide Quantum Optomechanics
Han-Jie Zhu, Xiao-Ming Zhao, Jin-Kui Zhao +3
We investigate polariton-phonon hybrid excitations, which describe the collective excitations of emitter-photon polaritons and vibrational phonons, in a periodic array of vibrating…
Non-Floquet engineering in periodically driven non-Hermitian systems
Huan-Yu Wang, Xiao-Ming Zhao, Lin Zhuang +1
Floquet engineering, modulating quantum systems in a time periodic way, lies at the central part for realizing novel topological dynamical states. Thanks to the Floquet engineering…
Exact solution of non-Hermitian systems with generalized boundary conditions: size-dependent boundary effect and fragility of skin effect
Cui-Xian Guo, Chun-Hui Liu, Xiao-Ming Zhao +2
Systems with non-Hermitian skin effects are very sensitive to the imposed boundary conditions and lattice size, and thus an important question is whether non-Hermitian skin effects…
Defective Majorana zero modes in non-Hermitian Kitaev chain
Xiao-Ming Zhao, Cui-Xian Guo, Su-Peng Kou +2
Topological stability is an important property for topological materials. However, the non-Hermitian effects may change this situation. Here, we investigate the robustness of edge…
Irrational Non-Abelian Statistics for Non-Hermitian Generalization of Majorana Zero Modes
Xiao-Ming Zhao, Cui-Xian Guo, Meng-Lei Yang +3
In condensed matter physics, non-Abelian statistics for Majorana zero modes (or Majorana Fermions) is very important, really exotic, and completely robust. The race for searching M…
Effective non-Hermitian physics for degenerate ground states of a nonHermitian Ising model with symmetry
Can Wang, Meng-Lei Yang, Cui-Xian Guo +2
In this paper, based on a one-dimensional non-Hermitian spin model with -invariant term, we study the non-Hermitian physics for the two (nearly) degenerate ground sta…
Fermi Arcs in Tilted Weyl Semimetals: Classification, Evolution and Transport Properties
Xiao-Ming Zhao, Xiao Kong, Cui-Xian Guo +2
The Weyl semimetal is a new quantum state of topological semimetal, of which topological surface states -- the Fermi arcs exist. In this paper, the Fermi arcs in Weyl semimetals ar…
The Simulation of Non-Abelian Statistics of Majorana Fermions in Ising Chain with Z2 Symmetry
Xiao-Ming Zhao, Jing Yu, Jing He +3
In this paper, we numerically study the non-Abelian statistics of the zero-energy Majorana fermions on the end of Majorana chain and show its application to quantum computing by ma…
Electronic transport of bilayer graphene with asymmetry line defects
