Confinement and bound states of bound states in a transverse-field two-leg Ising ladder
Flavia B. Ramos, Mate Lencses, J. C. Xavier +1
Weakly coupled Ising chains provide a condensed-matter realization of confinement. In these systems, kinks and antikinks bind into mesons due to an attractive interaction potential…
Relaxation and entropy generation after quenching quantum spin chains
M. Lencses, O. Pomponio, G. Takacs
This work considers entropy generation and relaxation in quantum quenches in the Ising and -state Potts spin chains. In the absence of explicit symmetry breaking we find univers…
Greenberger-Horne-Zeilinger state generation with linear optical elements
Bertúlio de Lima Bernardo, M. Lencśes, S. Brito +1
We propose a scheme to probabilistically generate Greenberger-Horne-Zeilinger (GHZ) states encoded on the path degree of freedom of three photons. These photons are totally indepen…
Chiral entanglement in massive quantum field theories in 1+1 dimensions
Mate Lencses, Jacopo Viti, Gabor Takacs
We determine both analytically and numerically the entanglement between chiral degrees of freedom in the ground state of massive perturbations of 1+1 dimensional conformal field th…
Kerr-de Sitter Quasinormal Modes via Accessory Parameter Expansion
Fábio Novaes, Cássio Marinho, Máté Lencsés +1
Quasinormal modes are characteristic oscillatory modes that control the relaxation of a perturbed physical system back to its equilibrium state. In this work, we calculate QNM freq…
