Biorthogonal Conformal Dynamics in Non-Hermitian Quantum Quenches
Yifan Liu
Global quenches at one-dimensional critical points admit a boundary conformal field theory (BCFT) description in which Euclidean strip correlators are analytically continued to rea…
Extracting Boundary Conformal Data from Periodic Non-Hermitian Critical Chains
Yifan Liu, Haruki Shimizu, Dongchang Liu +1
Boundary conformal field theory (BCFT) contains universal data that are usually accessed microscopically by imposing spatial boundaries on the lattice. In non-Hermitian many-body s…
Boundary critical phenomena in the quantum Ashkin-Teller model
Yifan Liu, Natalia Chepiga, Yoshiki Fukusumi +1
We investigate the boundary critical phenomena of the one-dimensional quantum Ashkin-Teller model using boundary conformal field theory and density matrix renormalization group (DM…
Self-congruent point in critical matrix product states: An effective field theory for finite-entanglement scaling
Jan T. Schneider, Atsushi Ueda, Yifan Liu +3
We set up an effective field theory formulation for the renormalization flow of matrix product states (MPS) with finite bond dimension, focusing on systems exhibiting finite-entang…
Finite-size corrections to the energy spectra of gapless one-dimensional systems in the presence of boundaries
Yifan Liu, Haruki Shimizu, Atsushi Ueda +1
We present the finite-size scaling theory of one-dimensional quantum critical systems in the presence of boundaries. While the finite-size spectrum in the conformal limit, namely o…
