Journal ArticleDOI
Initial states in integrable quantum field theory quenches from an integral equation hierarchy
TL;DR: In this paper, the authors considered the problem of determining the initial state of integrable quantum field theory quenches in terms of the post-quench eigenstates, and constructed an infinite integral equation hierarchy based on the form factor bootstrap.
Journal ArticleDOI
Symmetry resolved entanglement in integrable field theories via form factor bootstrap
TL;DR: In this paper, the authors considered the form factor bootstrap approach of integrable field theories to derive matrix elements of composite branch-point twist fields associated with symmetry resolved entanglement entropies.
Journal ArticleDOI
U(1) symmetry resolved entanglement in free 1+1 dimensional field theories via form factor bootstrap
TL;DR: In this paper, the authors generalized the form factor bootstrap approach to integrable field theories with U(1) symmetry to derive matrix elements of composite branch-point twist fields associated with symmetry resolved entanglement entropies.
Journal ArticleDOI
Overlaps after quantum quenches in the sine-Gordon model
David X. Horvath,Gábor Takács +1 more
TL;DR: In this article, a numerical computation of overlaps in mass quenches in sine-Gordon quantum field theory using truncated conformal space approach (TCSA) is presented.
Journal ArticleDOI
Nonequilibrium time evolution and rephasing in the quantum sine-Gordon model
TL;DR: In this article, the authors discuss the non-equilibrium time evolution of the phase field in the sine-Gordon model using two very different approaches: the truncated Wigner approximation and truncated conformal space approach, and demonstrate that the two approaches agree for a period covering the first few oscillations.
