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…
Tensor network simulations for nonorientable surfaces
Haruki Shimizu, Atsushi Ueda
In this study, we explore the geometric construction of the Klein bottle and the real projective plane () within the framework of tensor networks, focusing on the im…
Complex entanglement entropy for complex conformal field theory
Haruki Shimizu, Kohei Kawabata
Conformal field theory underlies critical ground states of quantum many-body systems. While conventional conformal field theory is associated with positive central charges, nonunit…
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…
