We construct a periodically time-dependent Hamiltonian with a phase transition in the quantum Hall universality class. One spatial dimension can be eliminated by introducing a second incommensurate driving frequency, so that we can study the quantum Hall effect in a one-dimensional (1D) system. This reduction to 1D is very efficient computationally and would make it possible to perform experiments on the 2D quantum Hall effect using cold atoms in a 1D optical lattice.

Geometry of random potentials: Induction of two-dimensional gravity in quantum Hall plateau transitions

Integer quantum Hall plateau transitions are usually modeled by a system of noninteracting electrons moving in a random potential. The physics of the most relevant degrees of freedom, the edge

Quantum Hall criticality in Floquet topological insulators

Topological Floquet Anderson Insulators (TFAIs) are systems in which an interplay of topology, driving, and static disorder stabilizes a unique form of topological quantum matter. Here, the authors

Edge-state critical behavior of the integer quantum Hall transition

The integer quantum Hall effect features a paradigmatic quantum phase transition. Despite decades of work, experimental, numerical, and analytical studies have yet to agree on a unified understanding

Self-duality triggered dynamical transition

A basic result about the dynamics of spinless quantum systems is that the Maryland model exhibits dynamical localization in any dimension. Here we implement mathematical spectral theory and numerical

Deep Learning the Quantum Phase Transitions in Random Two-Dimensional Electron Systems

Random electron systems show rich phases such as Anderson insulator, diffusive metal, quantum and anomalous quantum Hall insulator, Weyl semimetal, as well as strong/weak topological insulators.

Localization-length exponent in two models of quantum Hall plateau transitions

Motivated by the recent numerical studies on the Chalker-Coddington network model that found a larger-than-expected critical exponent of the localization length characterizing the integer quantum

Critical exponent for the Anderson transition in the three-dimensional orthogonal universality class

We report a careful finite size scaling study of the metal–insulator transition in Anderson's model of localization. We focus on the estimation of the critical exponent ν that describes the

Applications: Transport Coefficients at Finite Temperature

In the first part of the Chapter, we show that the non-commutative Kubo-formula for the transport coefficients is covered by the theory developed so far. In the second part, we present computer

Critical behavior at the integer quantum Hall transition in a network model on the kagome lattice

We study a network model on the Kagome lattice (NMKL). This model generalizes the Chalker-Coddington (CC) network model for the integer quantum Hall transition. Unlike random network models we
