Quantum relaxation after a quench in systems with boundaries
Ferenc Iglói, Heiko Rieger
We study the time-dependence of the magnetization profile, m_l(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with…
Infinite disorder scaling of random quantum magnets in three and higher dimensions
Istvan A. Kovacs, Ferenc Igloi
Using a very efficient numerical algorithm of the strong disorder renormalization group method we have extended the investigations about the critical behavior of the random transve…
Nonequilibrium phase transition in a driven Potts model with friction
Ferenc Igloi, Michel Pleimling, Loic Turban
We consider magnetic friction between two systems of -state Potts spins which are moving along their boundaries with a relative constant velocity . Due to the interaction bet…
Interface mapping in two-dimensional random lattice models
M. Karsai, J-Ch. Angles d'Auriac, F. Igloi
We consider two disordered lattice models on the square lattice: on the medial lattice the random field Ising model at T=0 and on the direct lattice the random bond Potts model in…
Renormalization group study of the two-dimensional random transverse-field Ising model
Istvan A. Kovacs, Ferenc Igloi
The infinite disorder fixed point of the random transverse-field Ising model is expected to control the critical behavior of a large class of random quantum and stochastic systems…
Anomalous diffusion in disordered multi-channel systems
R. Juhász, F. Iglói
We study diffusion of a particle in a system composed of K parallel channels, where the transition rates within the channels are quenched random variables whereas the inter-channel…
