Quantum Potts chain in alternating field
Péter Lajkó. Wedade Alaaeldin Ahmed Shafik Yehia, Ferenc Iglói
The -state Potts chain with ferromagnetic couplings, , in the presence of a transverse field, , has a quantum phase transition at , which is continuous for $q \le…

Griffiths-McCoy singularities in random quantum spin chains: Exact results through renormalization
Ferenc Igloi, Robert Juhasz, Peter Lajko
The Ma-Dasgupta-Hu renormalization group (RG) scheme is used to study singular quantities in the Griffiths phase of random quantum spin chains. For the random transverse-field Isin…

Boundary critical behaviour of two-dimensional random Ising models
F. Igloi, P. Lajko, W. Selke +1
Using Monte Carlo techniques and a star-triangle transformation, Ising models with random, 'strong' and 'weak', nearest-neighbour ferromagnetic couplings on a square lattice with a…
