Lieb-Schultz-Mattis Theorem in Open Quantum Systems
Kohei Kawabata, Ramanjit Sohal, Shinsei Ryu
The Lieb-Schultz-Mattis (LSM) theorem provides a general constraint on quantum many-body systems and plays a significant role in the Haldane gap phenomena and topological phases of…
Multipartite entanglement in two-dimensional chiral topological liquids
Yuhan Liu, Yuya Kusuki, Jonah Kudler-Flam +2
The multipartite entanglement structure for the ground states of two dimensional topological phases is an interesting albeit not well understood question. Utilizing the bulk-bounda…
Entanglement in tripartitions of topological orders: a diagrammatic approach
Ramanjit Sohal, Shinsei Ryu
Recent studies have demonstrated that measures of tripartite entanglement can probe data characterizing topologically ordered phases to which bipartite entanglement is insensitive.…
Theory of oblique topological insulators
Benjamin Moy, Hart Goldman, Ramanjit Sohal +1
A long-standing problem in the study of topological phases of matter has been to understand the types of fractional topological insulator (FTI) phases possible in 3+1 dimensions. U…
Multipartitioning topological phases by vertex states and quantum entanglement
Yuhan Liu, Ramanjit Sohal, Jonah Kudler-Flam +1
We discuss multipartitions of the gapped ground states of (2+1)-dimensional topological liquids into three (or more) spatial regions that are adjacent to each other and meet at poi…
Thermalization of Randomly Coupled SYK Models
Ramanjit Sohal, Laimei Nie, Xiao-Qi Sun +1
We investigate the thermalization of Sachdev-Ye-Kitaev (SYK) models coupled via random interactions following quenches from the perspective of entanglement. Previous studies have s…
