Quantum criticality and first-order transitions in the extended periodic Anderson model
I. Hagymasi, K. Itai, J. Solyom
We investigate the behavior of the periodic Anderson model in the presence of - Coulomb interaction () using mean-field theory, variational calculation, and exact dia…
Shear induced alignment and dynamics of elongated granular particles
Tamas Borzsonyi, Balazs Szabo, Sandra Wegner +5
The alignment, ordering and rotation of elongated granular particles was studied in shear flow. The time evolution of the orientation of a large number of particles was monitored i…
Boundary critical phenomena of the random transverse Ising model in D>=2 dimensions
István A. Kovács, Ferenc Iglói
Using the strong disorder renormalization group method we study numerically the critical behavior of the random transverse Ising model at a free surface, at a corner and at an edge…
Critical velocity of antiferromagnetic spin-1 Bose-Einstein condensates at finite temperature
Gergely Szirmai
We study the instability of a moving spinor Bose-Einstein condensate when the speed of flow reaches the critical velocity. This we identify on the basis of Landau's criterion, i.e.…
Corner contribution to percolation cluster numbers
István A. Kovács, Ferenc Iglói, John Cardy
We study the number of clusters in two-dimensional (2d) critical percolation, N_Gamma, which intersect a given subset of bonds, Gamma. In the simplest case, when Gamma is a simple…
Disordered contact process with asymmetric spreading
Róbert Juhász
An asymmetric variant of the contact process where the activity spreads with different and independent random rates to the left and to the right is introduced. A real space renorma…
