Non-Hermitian Statistical Geometry

Xi Hu, Yan-Qiong Ma, Su-Peng Kou

Particle exchange in two dimensions gives rise to quantum statistics beyond the boson-fermion dichotomy, with central roles in fractional quantum Hall physics, topological quantum…

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…

Dissipation driven boundary localization in higher order topological insulators

Xue Ping Ren, Xiao Ran Wang, Xin Ran Ma +2

We study dissipation driven boundary localization in a Bernevig Hughes Zhang type second order topological insulator by introducing inhomogeneous, spin dependent boundary dissipati…

Non-Hermitian skin effect induced by spatial noncommutativity

Zheng Wei, Su-Peng Kou

In all known schemes for the non-Hermitian skin effect, the non-Hermitian ingredient that drives the skin localization, whether asymmetric hopping or gain and loss, is invariably i…

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…

Tuning Topological States by Dissipation

Xue-Ping Ren, Yue Hu, Long-Ye Lu +4

The bulk-boundary correspondence plays a crucial role in topological quantum systems, however,this principle is broken in non-Hermitian systems. The breakdown of the bulk-boundary…

A Unified Framework for the Non-Hermitian Localization: Boundary-Insensitive Modes and Electric-Magnetic Analogy

Zheng Wei, Ji-Yao Fan, Kui Cao +4

The non-Hermitian skin effect is fundamentally characterized by its sensitivity to boundary conditions, reflected in changes to the energy spectrum and boundary-localized eigenstat…

Information Thermodynamics of Non-Hermitian Quantum Systems

Kui Cao, Qian Du, Su-Peng Kou

In this study, we uncover the intrinsic information processes in non-Hermitian quantum systems and their thermodynamic effects. We demonstrate that these systems can exhibit negati…

Deconfined quantum criticality of frustrated hard-core dipolar bosons

Ya-Nan Wang, Wen-Long You, Wen-Yi Zhang +2

Deconfined quantum critical points (DQCPs) are proposed as unconventional second-order phase transitions beyond the Landau-Ginzburg-Wilson paradigm. The nature and experimental rea…

Quantum Physics -- A Theory of Dynamics for "Space" on Space

Su-Peng Kou

Till now, the foundation of quantum physics is still mysterious. To explore the mysteries in the foundation of quantum physics, people always take it for granted that quantum proce…

Many-body phase transitions in a non-Hermitian Ising chain

Chao-Ze Lu, Xiaolong Deng, Su-Peng Kou +1

We study many-body phase transitions in a one-dimensional ferromagnetic transversed field Ising model with an imaginary field and show that the system exhibits three phase transiti…
