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.…

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…
