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…
Magnetization oscillations in a periodically driven transverse field Ising chain
Xiao Wang, Masaki Oshikawa, Márton Kormos +1
We investigate the nonequilibrium dynamics of the magnetization in an Ising chain subjected to a slowly rotating transverse field. The magnetization oscillations are found to be ex…
Intrinsic mixed-state SPT from modulated symmetries and hierarchical structure of anomaly
Yizhi You, Masaki Oshikawa
We introduce a class of intrinsic symmetry-protected topological mixed-state(mSPT) in open quantum systems that feature modulated symmetries, such as dipole and subsystem symmetrie…
Spontaneous Strong Symmetry Breaking in Open Systems: Purification Perspective
Pablo Sala, Sarang Gopalakrishnan, Masaki Oshikawa +1
We explore the landscape of the decoherence effect in mixed-state ensembles from a purification perspective. We analyze the spontaneous strong-to-weak symmetry breaking (SSSB) in m…
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…
