Chirally Factorised Truncated Conformal Space Approach
D. X. Horvath, K. Hodsagi, G. Takacs
Truncated Conformal Space Approach (TCSA) is a highly efficient method to compute spectra, operator matrix elements and time evolution in quantum field theories defined as relevant…
Inhomogeneous quantum quenches in the sine-Gordon theory
D. X. Horváth, M. Kormos, S. Sotiriadis +1
We study inhomogeneous quantum quenches in the attractive regime of the sine-Gordon model. In our protocol, the system is prepared in an inhomogeneous initial state in finite volum…
Collapse instability and staccato decay of oscillons in various dimensions
B. C. Nagy, G. Takacs
Oscillons are long-lived, slowly radiating solutions of nonlinear classical relativistic field theories. Recently it was discovered that in one spatial dimension their decay may pr…
Bloch oscillations and the lack of the decay of the false vacuum in a one-dimensional quantum spin chain
O. Pomponio, M. A. Werner, G. Zarand +1
We consider the decay of the false vacuum, realised within a quantum quench into an anti-confining regime of the Ising spin chain with a magnetic field opposite to the initial magn…
Weak integrability breaking and level spacing distribution
D. Szász-Schagrin, B. Pozsgay, G. Takács
Recently it was suggested that certain perturbations of integrable spin chains lead to a weak breaking of integrability in the sense that integrability is preserved at the first or…
Out-of-horizon correlations following a quench in a relativistic quantum field theory
Ivan Kukuljan, Spyros Sotiriadis, Gabor Takacs
One of the manifestations of relativistic invariance in non-equilibrium quantum field theory is the "horizon effect" a.k.a. light-cone spreading of correlations: starting from an i…
