Supersolid in a one-dimensional optical lattice in the presence of a harmonic trap
Supersolid in a one-dimensional optical lattice harmonic trap
2010/11/19
We study a system of ultra-cold atoms possessing long range interaction (e.g. dipole-dipole interaction)in a one dimensional optical lattice in the presence of a confining harmonic trap. We have shown...

Anomalous Bloch oscillations dimensional parity-breaking periodic potentials
2010/11/19
We investigate the dynamics of a wave packet in a parity-breaking one-dimensional periodic
potential slowly varied in time and perturbed by a linear potential. Parity is broken by considering an asym...
We use two fundamental theoretical frameworks to study the finite-size (shell) properties of the unitary gas in a periodic box: 1) an ab initio QuantumMonte Carlo (qmc) calculation for boxes containin...
Observation of exchange Coulomb interactions in the quantum Hall state at nu=3
exchange Coulomb interactions quantum Hall state
2010/11/19
Coulomb exchange interactions of electrons in the = 3 quantum Hall state are determined from
two inter-Landau level spin-flip excitations measured by resonant inelastic light scattering. The two co...

Tuning the spin texture ternary surface alloys
2010/11/19
Recently, a giant spin splitting has been observed in surface alloys on noble metal (111) surfaces as a result of a strong structural modification at the surface as well as the large atomic spin-orbit...
Helical Edge Modes near Transition to Topological Insulator with Indirect Gap
topological insulator edge mode indirect gap particle-hole symmetry semimetal annihilator
2010/11/19
Helical edge modes are characteristic of topological insulators in two dimensions. This paper
demonstrates that helical edge modes remain across transitions to ordinary insulators or to semimetals un...

2010/11/19
We calculate the rst order perturbation correction to the ground state energy and chemical
potential of a harmonically trapped boson gas with contact interactions about the in nite repulsion Tonks-G...
Shear bands in a continuum model of foams: how a 3D homogeneous material may seem inhomogeneous in 2D
Shear bands continuum model of foams
2010/11/17
We describe possible conditions for stationnary inhomogeneous flow behaviour (sheared and
blocked bands) in a continuous mechanical model of a soft visco-elasto-plastic material such as
a foam or a ...
Note and calculations concerning elastic dilatancy in 2D glass-glass liquid foams
Note calculations
2010/11/17
When deformed, liquid foams tend to raise their liquid contents like immersed granular materials,a phenomenon called dilatancy. We have aready described a geometrical interpretation of elastic dilatan...

Magnetotransport spin dynamics oxide interfaces
2010/11/23
We investigate the spin-dependent transport properties of a two-dimensional electron gas formed
at oxides’ interface in the presence of a magnetic field. We consider several scenarios for the oxides’...
