Generating function for Hermitian and non-Hermitian models
Hua-Yu Bai, Yang Chen, Guang-Can Guo +2
It is well known that Hermitian and non-Hermitian models exhibit distinct physics and require different theoretical tools. In this work, we propose a unified generating-function fr…
Coupling between vibration and Luttinger liquid in mechanical nanowires
Zeyu Rao, Yue-Xin Huang, Guang-Can Guo +1
The vibration of the mechanical nanowire coupled to photons via photon pressure and coupled to charges via the capacity has been widely explored in experiments in the past decades.…
Unilateral Criticality and Phase Transition in the Cavity-Ising Model
Zeyu Rao, Xiaoshui Lin, Xiwang Luo +3
Superradiant phase transitions from cavity light-matter coupling have been widely explored across platforms. Here, we report a unilateral critical endpoint (UCEP) and a tricritical…
Soliton and traveling wave solutions in coupled one-dimensional condensates
Zeyu Rao, Xiaoshui Lin, Jingsong He +2
Ultracold condensates provide a unique platform for exploring soliton physics. Motivated by the recent experiments realizing the sine-Gordon model in a split one-dimensional (1D) B…
Skin mode tunability and self-healing effect in photonic Floquet lattices
Hua-Yu Bai, Yang Chen, Tian-Yang Zhang +3
Non-Hermitian systems host exotic phenomena absent in their Hermitian counterparts, including the recently predicted self-healing effect (SHE) of non-Hermitian skin modes. To date,…
Uncovering the origin of bound state in the continuum
Zeyu Rao, Changling Zou, Yang Chen +2
Bound state in the continuum (BIC) and quasi-BIC represent a remarkable class of wave functions that disobey conventional intuition by exhibiting spatially localized modes embedded…
Brownian motion and generalized Lifson-Jackson formula in quasi-periodic systems
Sang Yang, Juyuan Sun, Guangcan Guo +1
Brownian motion in periodic potentials has been widely investigated in statistical physics and related interdisciplinary fields. In the overdamped regime, it has been well-known th…
Divergent density of states and non-analytic Lyapunov exponent in one-dimensional slowly varying systems
Hai-Tao Hu, Ming Gong, Guangcan Guo +1
Localization of wave functions in disordered systems can be characterized by the Lyapunov exponent, which is zero in the extended phase and nonzero in the localized phase. Previous…
Hermitian and Non-Hermitian Topological Transitions Characterized by Manifold Distance
ZhaoXiang Fang, Ming Gong, Guang-Can Guo +2
Topological phases are generally characterized by topological invariants denoted by integer numbers. However, different topological systems often require different topological inva…
Hidden self-duality and exact mobility edges in quasiperiodic network models
Hai-Tao Hu, Xiaoshui Lin, Ai-Min Guo +3
In one-dimensional quasiperiodic systems, only a few models with exact mobility edges (MEs) have been constructed using generalized self-duality theory, Avila's global theory, or t…
Distance between two manifolds, topological phase transitions and scaling laws
ZhaoXiang Fang, Ming Gong, Guang-Can Guo +2
Topological phases are generally characterized by topological invariants denoted by integer numbers. However, different topological systems often require different topological inva…
Theory of mobility edge and non-ergodic extended phase in coupled random matrices
Xiaoshui Lin, Guang-Can Guo, Ming Gong
The mobility edge, as a central concept in disordered models for localization-delocalization transitions, has rarely been discussed in the context of random matrix theory (RMT). He…
Quantumness and quantum to classical transition in the generalized Rabi model
Wei-Feng Zhuang, Yun-Tong Yang, Hong-Gang Luo +2
The quantum to classical transition (QCT) is one of the central mysteries in quantum physics. This process is generally interpreted as state collapse from measurement or decoherenc…
Atomistic theory of spin relaxation in self-assembled InGaAs/GaAs quantum dots at zero magnetic field
Hai Wei, Ming Gong, G-C Guo +1
We present full atomistic calculations of the spin-flip time (T) of electrons and holes mediated by acoustic phonons in self-assembled InGaAs/GaAs quantum dots at…
Atomistic pseudopotential calculations of the optical properties of InAs/InP self-assembled quantum dots
Ming Gong, Weiwei Zhang, Zhuming Han +2
We present a comprehensive study of the optical properties of InAs/InP self-assembled quantum dots (QDs) using an empirical pseudopotential method and configuration interaction tre…
