Long range transport of ultra cold atoms in a far-detuned 1D optical lattice
Long range transport ultra cold atoms far-detuned 1D optical lattice Atomic Physics
2012/4/27
We present a novel method to transport ultra cold atoms in a focused optical lattice over macroscopic distances of many Rayleigh ranges. With this method ultra cold atoms were transported over 5 cm in...

2011/9/16
Abstract: For various one-dimensional quantum liquids in the framework of the Luttinger model (bosonization) we establish the relations between the coefficients before the power-law asymptotics of the...

2011/7/25
Abstract: We study the 1D extended Hubbard model with a weak repulsive short-range interaction in the non-half-filled band case, using non-perturbative Renormalization Group methods and Ward Identitie...
Possible 2S and 1D charmed and charmed-strange mesons 。
运用准经典轨线法结合Peterson 从头计算势能面, 在碰撞能为0.22 eV 时对O(1D) +DBr(v=0, j=0) → OD+Br 反应进行了细致的立体动力学性质研究. 极化微分反应截面(PDDCSs)给出了反应产物的散射方向. 反映k 与j′ 两矢量相关的函数P(θr)的分布表明产物分子的转动角动量j′在垂直于反应物相对速度矢量k 的方向上有强烈的取向分布; 反映k, k′与j′三矢...
Mapping out the quasi-condensate transition through the 1D-3D dimensional crossover
quasi-condensate transition 1D-3D dimensional crossover
2010/11/23
By measuring the density fluctuations in a highly elongated weakly interacting Bose gas, we observe and quantify the transition from the ideal gas to a quasi-condensate regime throughout the dimension...
Coulomb interaction effects and electron spin relaxation in the 1d Kondo lattice model
Ludwig-Maximilians-Universit¨at M¨unchen University of Queensland
2010/11/23
We study the effects of the Coulomb interaction in the one dimensional Kondo lattice model on
the phase diagram, the static magnetic susceptibility and electron spin relaxation. We show that onsite C...

2010/11/25
The transition metal carbide Sc3CoC4 consists of a quasi-one-dimensional (1D)structure with [CoC4]1 polyanionic chains embedded in a scandium matrix. At ambient temperatures Sc3CoC4 displays metallic ...
On the possibility of obtaining MOSFET-like performance and sub-60 mV/decade swing in 1D broken-gap tunnel transistors
obtaining MOSFET-like performance sub-60 mV/decade
2010/11/25
Tunneling field-effect transistors (TFETs) have gained a great deal of recent interest due to their potential to reduce power dissipation in integrated circuits. One major challenge for TFETs so far h...
Stochastic quantum dynamics in 1D and lattice systems
Stochastic quantum dynamics 1D lattice systems
2010/10/21
We show that stochastic phase-space methods within the truncated Wigner approximation can be used to solve non-equilibrium dynamics of bosonic atoms in 1d traps. We consider systems both with and with...

Confinement limit Dirac particles scalar 1D potentials
2010/4/9
We present a general proof that Dirac particles cannot be localized below their Compton length by symmetric but otherwise arbitrary scalar potentials. This proof does not invoke the Heisenberg uncerta...
