Numerical and theoretical studies of the Anderson transition in the chiral symmetry classes with weak topology
Shiyin Kuang, Tong Wang, Zhenyu Xiao +2
Combining lattice-model simulations with a renormalization group (RG) analysis of effective theories, we investigate the nature of the Anderson transition in chiral symmetry classe…
Theory of the Anderson transition in three-dimensional chiral symmetry classes: Connection to type-II superconductors
Pengwei Zhao, Ryuichi Shindou
Phase transitions governed by topological defects constitute a cornerstone of modern physics. Two-dimensional (2D) Anderson transitions in chiral symmetry classes are driven by the…
Topological effect on the Anderson transition in chiral symmetry classes
Pengwei Zhao, Zhenyu Xiao, Yeyang Zhang +1
In this Letter, we propose a mechanism of an emergent quasi-localized phase in chiral symmetry classes, where wave function along a spatial direction with weak topology is delocali…
Anisotropic Topological Anderson Transitions in Chiral Symmetry Classes
Zhenyu Xiao, Kohei Kawabata, Xunlong Luo +2
We study quantum phase transitions of three-dimensional disordered systems in the chiral classes (AIII and BDI) with and without weak topological indices. We show that the systems…
Level statistics of real eigenvalues in non-Hermitian systems
Zhenyu Xiao, Kohei Kawabata, Xunlong Luo +2
Symmetries associated with complex conjugation and Hermitian conjugation, such as time-reversal symmetry and pseudo-Hermiticity, have great impact on eigenvalue spectra of non-Herm…
Multicriticality of Two-dimensional Class D Disordered Topological Superconductors
Tong Wang, Zhiming Pan, Tomi Ohtsuki +2
A generic two-dimensional disordered topological superconductor in symmetry class D exhibits rich phenomenology and multiple phases: diffusive thermal metal (DTM), Anderson insulat…

Two-dimensional (2D) disordered superconductor (SC) in class D exhibits a disorder-induced quantum multicritical phenomenon among diffusive thermal metal (DTM), topological superco…
Universality classes of the Anderson transition in three-dimensional symmetry classes AIII, BDI, C, D and CI

We clarify universal critical properties of delocalization-localization transitions in three-dimensional (3D) unitary and orthogonal classes with particle-hole and/or chiral symmet…
Universality classes of the Anderson Transitions Driven by non-Hermitian Disorder
Xunlong Luo, Tomi Ohtsuki, Ryuichi Shindou
An interplay between non-Hermiticity and disorder plays an important role in condensed matter physics. Here, we report the universal critical behaviors of the Anderson transitions…
Critical Behaviors of Anderson Transitions in Three Dimensional Orthogonal Classes with Particle-hole Symmetries
Xunlong Luo, Baolong Xu, Tomi Ohtsuki +1
From transfer-matrix calculation of localization lengths and their finite-size scaling analyses, we evaluate critical exponents of the Anderson metal-insulator transition in three…
Quantum Multicriticality in Disordered Weyl Semimetal
Xunlong Luo, Baolong Xu, Tomi Ohtsuki +1
In electronic band structure of solid state material, two band touching points with linear dispersion appear in pair in the momentum space. When they annihilate with each other, th…
Integer Quantum Magnon Hall Plateau-Plateau Transition in a Spin Ice Model
Baolong Xu, Tomi Ohtsuki, Ryuichi Shindou
Low-energy magnon bands in a two-dimensional spin ice model become integer quantum magnon Hall bands. By calculating the localization length and the two-terminal conductance of mag…
