Dissipative Majorana Chain---Anomalies and Non-Invertible Symmetries
Hung-Hsuan Teh, Tokiro Numasawa
We study symmetries and anomalies of dissipative Majorana chains described by Lindblad dynamics. Using the operator-state mapping, we represent the Lindbladian as a non-Hermitian o…

Krylov Complexity and Mixed-State Phase Transition
Hung-Hsuan Teh, Takahiro Orito
We establish a unified framework connecting decoherence and quantum complexity. By vectorizing the density matrix into a pure state in a double Hilbert space, a decoherence process…
