On the Thermal Transport Puzzles in -RuCl
Zheng-Duo Fan, Xiao-Qi Sun, Jing-Yuan Chen
Thermal transport has been used to probe the nature of -RuCl, an important candidate of Kitaev material. Two remarkable observations were made under applied magnetic fields…
Parent Lindbladians for Matrix Product Density Operators
Yuhan Liu, Alberto Ruiz-de-Alarcón, Georgios Styliaris +3
Understanding quantum phases of matter is a fundamental goal in physics. For pure states, the representatives of phases are the ground states of locally interacting Hamiltonians, w…
Anomalous matrix product operator symmetries and 1D mixed-state phases
Xiao-Qi Sun
Generalized symmetries have emerged as a powerful organizing principle for exotic quantum phases. However, their role in open quantum systems, especially for non-invertible cases,…
Trading Mathematical for Physical Simplicity: Bialgebraic Structures in Matrix Product Operator Symmetries
Yuhan Liu, Andras Molnar, Xiao-Qi Sun +3
Despite recent advances in the lattice representation theory of (generalized) symmetries, many simple quantum spin chains of physical interest are not included in the rigid framewo…
