Mixed-order phase transition of the contact process near multiple junctions
R. Juhász, F. Iglói
We have studied the phase transition of the contact process near a multiple junction of semi-infinite chains by Monte Carlo simulations. As opposed to the continuous transition…
Critical quench dynamics of random quantum spin chains: Ultra-slow relaxation from initial order and delayed ordering from initial disorder
Gergo Roosz, Yu-Cheng Lin, Ferenc Igloi
By means of free fermionic techniques combined with multiple precision arithmetic we study the time evolution of the average magnetization, , of the random transve…
Entanglement entropy of the quantum Potts chain
Péter Lajkó, Ferenc Iglói
The entanglement entropy, , is an indicator of quantum correlations in the ground state of a many body quantum system. At a second-order quantum phase-transition point in…
Phase-transitions of the random bond Potts chain with long-range interactions
Jean-Christian Anglès d'Auriac, Ferenc Iglói
We study phase-transitions of the ferromagnetic -state Potts chain with random nearest-neighbour couplings having a variance and with homogeneous long-range interactions,…
