Gauge theory and mixed state criticality
T Ando, S Ryu, M Watanabe - arxiv preprint arxiv:2411.04360, 2024 - arxiv.org
In mixed quantum states, the notion of symmetry is divided into two types: strong and weak
symmetry. While spontaneous symmetry breaking (SSB) for a weak symmetry is detected by …

Many-body quantum catalysts for transforming between phases of matter
A catalyst is a substance that enables otherwise impossible transformations between states
of a system, without being consumed in the process. In this work, we apply the notion of …

Boundary anomaly detection in two-dimensional subsystem symmetry-protected topological phases
K Ding, HR Zhang, BT Liu, S Yang - arxiv preprint arxiv:2412.07563, 2024 - arxiv.org
We develop a method to detect quantum anomalies in systems with subsystem symmetry,
building on the concept of anomaly indicators. This approach allows us to distinguish …

Dissipation-assisted preparation of topological boundary states
Y Peng, C Yang, H Hu, Y Wang - arxiv preprint arxiv:2412.04152, 2024 - arxiv.org
Robust states emerging at the boundaries of a system are an important hallmark of
topological matter. Here, using the Su-Schrieffer-Heeger model and the Kitaev chain as …
