Nonequilibrium quench dynamics in quantum quasicrystals
Ferenc Igloi, Gergo Roosz, Yu-Cheng Lin
We study the nonequilibrium dynamics of a quasiperiodic quantum Ising chain after a sudden change in the strength of the transverse field at zero temperature. In particular we cons…
Entanglement entropy dynamics of disordered quantum spin chains
Ferenc Igloi, Zsolt Szatmari, Yu-Cheng Lin
By means of free fermionic techniques we study the time evolution of the entanglement entropy, S(t), of a block of spins in the random transverse-field Ising chain after a sudden c…
Entanglement entropy with localized and extended interface defects
Ferenc Iglói, Zsolt Szatmári, Yu-Cheng Lin
The quantum Ising chain of length, L, which is separated into two parts by localized or extended defects is considered at the critical point where scaling of the interface magnetiz…
Finite-size scaling of the entanglement entropy of the quantum Ising chain with homogeneous, periodically modulated and random couplings
Ferenc Igloi, Yu-Cheng Lin
Using free-fermionic techniques we study the entanglement entropy of a block of contiguous spins in a large finite quantum Ising chain in a transverse field, with couplings of diff…
Path integral Monte Carlo study of the interacting quantum double-well model: Quantum phase transition and phase diagram
Dong-Hee Kim, Yu-Cheng Lin, Heiko Rieger
The discrete time path integral Monte Carlo (PIMC) with a one-particle density matrix approximation is applied to study the quantum phase transition in the coupled double-well chai…
Optimization by Move--Class Deflation
Reimer Kuehn, Yu-Cheng Lin, Gerhard Poeppel
A new approach to combinatorial optimization based on systematic move-class deflation is proposed. The algorithm combines heuristics of genetic algorithms and simulated annealing,…
