Non-Perturbative Prediction of the Ferromagnetic Transition in Repulsive Fermi Gases
Fermi Gases Ferromagnetic Transition
2011/7/21
It is generally believed that a dilute spin-1/2 Fermi gas with repulsive interactions can undergo a ferromagnetic phase transition to a spin-polarized state at a critical gas parameter $(k_{\text F}a)...
Phase diagram of Rydberg atoms with repulsive van der Waals interaction
Phase diagram of Rydberg atoms
2011/9/14
We report a quantum Monte Carlo calculation of the phase diagram of bosons interacting with a repulsive inverse sixth power pair potential, a model for assemblies of Rydberg atoms in the local van der...
A consequence of the repulsive Casimir-Lifshitz force on nano-scale and the related Wheeler propagator in the classical electrodynamics
repulsive Casimir-Lifshitz force nano-scale related Wheeler propagator
2010/12/24
Mainly on nano-scale, but maybe not exclusively, it can be imagined a spontaneous charge disjunction inside certain media due to the fluctuations, collisions, wall effects, radiation or/and other pre...
Repulsive and Restoring Casimir Forces Based on Magneto-Optical Effect
Repulsive Restoring Casimir Forces Magneto-Optical Effect
2014/5/28
The Casimir force direction tuned by the external magnetic field due to the magneto-optical Voigt effect is investigated. The magneto-optical effect gives rise to the modified frequency-dependent elec...
Synchronisation Induced by Repulsive Interactions in a System of van der Pol Oscillators
Synchronisation Repulsive Interactions van der Pol Oscillators
2010/11/22
We consider a system of identical van der Pol oscillators, globally coupled through their
velocities, and study how the presence of competitive interactions affects its synchronisation
properties. W...
Mapping between Hamiltonians with attractive and repulsive potentials on a lattice
Mapping Hamiltonians attractive repulsive potentials
2010/10/21
Through a simple and exact analytical derivation, we show that for a particle on a lattice, there is a one-to-one correspondence between the spectra in the presence of an attractive potential ˆ V...
Repulsive Casimir forces with finite-thickness functional slabs
Repulsive Casimir finite-thickness functional slabs
2010/10/21
We use the extended Lifshitz theory to study the behavior of the Casimir forces between finite-thickness functional slabs. We first study the interaction between a semi-infinite Drude metal and a fini...
Resonance induced by repulsive interactions in a model of globally-coupled bistable systems
Resonance induced globally-coupled bistable systems repulsive interactions
2010/4/1
We show the existence of a competition-induced resonance effect for a generic globally coupled bistable system. In particular, we demonstrate that the response of the macroscopic variable to an extern...
Repulsive and attractive ferroglasses: a SAXS and XPCS study
75.50.Mn Magnetic liquids 61.10.-i X-ray diffraction and scattering 82.70.Dd Colloids 64.70.Pf Glass transitions
2010/7/5
A dynamical freezing, which is the analogous of a glass transition, is observed at large concentrations in aqueous dispersions of maghemite nanoparticles. We study experimentally the structure and the...

Simple models of complex aggregation: vesicles formation by soft repulsive spheres with dipole-like interactions
thermodynamic properties simple model
2007/7/11
Structural and thermodynamic properties of spherical particles carrying classical spins are in-vestigated by Monte Carlo simulations. The potential energy is the sum of short range, purely repulsive p...
