Far-from-equilibrium topological phase transition in one dimension
Ze-Min Huang, Gustav John, Sebastian Diehl
We uncover a mechanism for far-from-equilibrium topological phase transitions, via a one-dimensional compact phase model evolving deterministically from random initial conditions.…
Anomaly and symmetry-charge flow in mixed states
Ze-Min Huang, Sebastian Diehl
The -dimensional chiral anomaly is a paradigmatic exact result in quantum field theory, traditionally formulated for zero-temperature pure states where it arises from spectr…
Topological response in open quantum systems with weak symmetries
Ze-Min Huang, Sebastian Diehl, Xiao-Qi Sun
In open quantum systems, the interaction of the system with its environment gives rise to two types of symmetry: a strong one, where the system's symmetry charge is conserved exact…
Coherent information as a mixed-state topological order parameter of fermions
Ze-Min Huang, Luis Colmenarez, Markus Müller +1
Quantum error correction protects quantum information against decoherence provided the noise strength remains below a critical threshold. This threshold marks the critical point fo…
Interaction-induced topological phase transition at finite temperature
Ze-Min Huang, Sebastian Diehl
We demonstrate the existence of topological phase transitions in interacting, symmetry-protected quantum matter at finite temperatures. Using a combined numerical and analytical ap…
Mixed state topological order parameters for symmetry protected fermion matter
Ze-Min Huang, Sebastian Diehl
We construct an observable mixed state topological order parameter for symmetry-protected free fermion matter. It resolves the entire table of topological insulators and supercondu…
Accurate optimal quantum error correction thresholds from coherent information
Luis Colmenarez, Ze-Min Huang, Sebastian Diehl +1
Quantum error correcting (QEC) codes protect quantum information from decoherence, as long as error rates fall below critical error thresholds. In general, obtaining thresholds imp…
Topological gauge theory for mixed Dirac stationary states in all dimensions
Ze-Min Huang, Xiao-Qi Sun, Sebastian Diehl
We derive the universal real time topological gauge field action for mixed quantum states of weakly correlated fermions in all dimensions, and demonstrate its independence o…
Torsion, energy magnetization and thermal Hall effect
Ze-Min Huang, Bo Han, Xiao-Qi Sun
We study the effective action of hydrostatic response to torsion in the absence of spin connections in gapped -dimensional topological phases. In previous studies…
