Fermi gas with attractive potential and arbitrary spin in one-dimensional trap
Fermi gas attractive potential arbitrary spin one-dimensional trap
2011/8/18
Abstract: A gas of ultracold $^6$Li atoms (effective spin 1/2) confined to an elongated trap with one-dimensional properties is a candidate to display three different phases: (i) fermions bound in Coo...
Long timescale dynamics of spin textures in a degenerate F=1 $^{87}$ Rb spinor Bose gas
Long timescale dynamics spin textures Rb spinor Bose gas
2011/8/17
Abstract: We investigate the long-term dynamics of spin textures prepared by cooling unmagnetized spinor gases of F=1 $^{87}$Rb to quantum degeneracy, observing domain coarsening and a strong dependen...
Simulation of spin-polarized scanning tunneling microscopy on complex magnetic surfaces: The case of a Cr monolayer on Ag(111)

2011/8/17
Abstract: We propose an atom-superposition-based method for simulating spin-polarized scanning tunneling microscopy (SP-STM) from first principles. Our approach provides bias dependent STM images in h...
Coherent manipulation of spin wave vector for polarization of photons in an atomic ensemble

2011/8/3
Abstract: We experimentally demonstrate the manipulation of two-orthogonal components of a spin wave in an atomic ensemble. Based on Raman two-photon transition and Larmor spin precession induced by m...

Orientation-to-alignment conversion spin squeezing
2011/9/2
The relationship between orientation-to-alignment conversion (a form of atomic polarization evolution induced by an electric eld) and the phenomenon of spin squeezing is demonstrated. A \stretched" s...
Ultracold spin-polarized mixtures of 2Sigma molecules with S-state atoms: Collisional stability and implications for sympathetic cooling
S-state atoms physics and chemistry molecular
2011/8/31
The prospects of sympathetic cooling of polar molecules with magnetically co-trapped alkalimetal atoms are generally considered poor due to strongly anisotropic atom-molecule interactions leading to l...
Prefect Transfer of Quantum States on Spin Chain with Dzyaloshinskii- Moriya interaction in inhomogeneous Magnetic field
XY Spin-Chain Teleportation Dzyaloshinskii-Moriya interaction
2010/10/29
In this work, we use the Hamiltonian of a modified Dzyaloshinskii-Moriya model and investigate the perfect transfer of the quantum state on the spin networks. In this paper, we calculate fidelity in w...

Spin-squeezed atoms interferometry atomic clocks
2010/4/15
Physicists in Germany are the first to use "spin-squeezed" atoms to boost the precision of an interferometer based on interacting atoms. Their work involves entangling several hundred atoms in a way t...
Periodic spin textures in a degenerate F=1 $^{87}$Rb spinor Bose gas
Periodic spin textures degenerate F=1 $^{87}$Rb spinor Bose gas
2010/4/13
We report on the spin textures produced by cooling unmagnetized $^{87}$Rb F=1 spinor gases into the regime of quantum degeneracy. At low temperatures, magnetized textures form that break translational...

Skyrme force spin-orbit interaction exotic nuclei sulfur isotopes
2009/8/14
The effects of the spin-orbit interaction in exotic nuclei are investigated by studying the binding energies and deformations of Si, S and Ar isotopes. The calculations were obtained by Skyrme-Hartree...

2010/10/19
We review recently developed decomposition algorithms for molecular dynamics and spin dynamics simulations of many-body systems. These methods are time reversible, symplectic, and the error in the tot...
