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…
