Cascade of singularities in the spin dynamics of a perturbed quantum critical Ising chain
Xiao Wang, Haiyuan Zou, Kristóf Hódsági +3
When the quantum critical transverse-field Ising chain is perturbed by a longitudinal field, a quantum integrable model emerges in the scaling limit with massive excitations descri…
Kibble-Zurek mechanism in the Ising Field Theory
Kristóf Hódsági, Márton Kormos
The Kibble-Zurek mechanism captures universality when a system is driven through a continuous phase transition. Here we study the dynamical aspect of quantum phase transitions in t…
Spectra of Quasi-one-dimensional Antiferromagnet BaCoVO under Transverse Field
Haiyuan Zou, Y. Cui, X. Wang +16
We report V nuclear magnetic resonance (NMR) and inelastic neutron scattering (INS) measurements on a quasi-1D antiferromagnet BaCoVO under transverse field alon…
Perturbative post-quench overlaps in Quantum Field Theory
Kristóf Hódsági, Márton Kormos, Gábor Takács
In analytic descriptions of quantum quenches, the overlaps between the initial pre-quench state and the eigenstates of the time evolving Hamiltonian are crucial ingredients. We con…
Quench dynamics of the Ising field theory in a magnetic field
Kristóf Hódsági, Márton Kormos, Gábor Takács
We numerically simulate the time evolution of the Ising field theory after quenches starting from the integrable model using the Truncated Conformal Space Approach. The resul…
