Disordered Potts model on the diamond hierarchical lattice: Numerically exact treatment in the large-q limit
Ferenc Igloi, Loic Turban
We consider the critical behavior of the random q-state Potts model in the large-q limit with different types of disorder leading to either the nonfrustrated random ferromagnet reg…
Numerical investigation of the aging of the Fully-Frustrated XY model
Jean-Charles Walter, Christophe Chatelain
We study the out-of-equilibrium dynamics of the fully-frustrated XY model. At equilibrium, this model undergoes two phase transitions at two very close temperatures: a Kosterlitz-T…
Gradient critical phenomena in the Ising quantum chain: surface behaviour
Mario Collura, Dragi Karevski, Loïc Turban
We consider the influence of a power-law deviation from the critical coupling such that the system is critical at its surface. We develop a scaling theory showing that such a pertu…
Ageing in bosonic particle-reaction models with long-range transport
Xavier Durang, Malte Henkel
Ageing in systems without detailed balance is studied in bosonic contact and pair-contact processes with Levy diffusion. In the ageing regime, the dynamical scaling of the two-time…
Silicon surface with giant spin-splitting
I. Gierz, T. Suzuki, E. Frantzeskakis +7
We demonstrate the induction of a giant Rashba-type spin-splitting on a semiconducting substrate by means of a Bi trimer adlayer on a Si(111) wafer. The in-plane inversion symmetry…
Distortion of the Stoner-Wohlfarth astroid by a spin-polarized current
Y. Henry, S. Mangin, J. Cucchiara +2
The Stoner-Wohlfarth astroid is a fundamental object in magnetism. It separates regions of the magnetic field space with two stable magnetization equilibria from those with only on…
