Relaxation Process During Complex Time Evolution In Two-Dimensional Integrable and Chaotic CFTs
Chen Bai, Weibo Mao, Masahiro Nozaki +2
We investigate the complex time evolution of a vacuum state with the insertion of a local primary operator in two-dimensional conformal field theories (2d CFTs). This complex time…
Impurity-induced non-unitary criticality
Heng-Hsi Li, Kuang-Hung Chou, Xueda Wen +1
Quantum impurities give rise to rich physical phenomena, with some exhibiting critical behavior described by conformal field theories (CFTs) in the low-energy limit. In parallel, p…
Higher Berry Curvature from the Wave function II: Locally Parameterized States Beyond One Dimension
Ophelia Evelyn Sommer, Ashvin Vishwanath, Xueda Wen
We propose a systematic wave function based approach to construct topological invariants for families of lattice systems that are short-range entangled using local parameter spaces…
Higher Berry Curvature from the Wave Function I: Schmidt Decomposition and Matrix Product States
Ophelia Evelyn Sommer, Xueda Wen, Ashvin Vishwanath
Higher Berry curvature (HBC) is the proposed generalization of Berry curvature to infinitely extended systems. Heuristically HBC captures the flow of local Berry curvature in a sys…
