Ground state sideband cooling of an ion in a room temperature trap with a sub-Hertz heating rate
Ground state sideband ion sub-Hertz heating rate Atomic Physics
2012/5/29
We demonstrate resolved sideband laser cooling of a single 40Ca+ ion in a macroscopic linear radio frequency trap with a radial diagonal electrode spacing of 7 mm and an rf drive frequency of just 3.7...
Spectrally narrow, long-term stable optical frequency reference based on a Eu$^{3+}$:Y$_{2}$SiO$_{5}$ crystal at cryogenic temperature
Spectrally narrow long-term stable optical frequency reference cryogenic temperature
2011/8/5
Abstract: Using an ultrastable continuous-wave laser at 580 nm we performed spectral hole burning of Eu$^{3+}$:Y$_{2}$SiO$_{5}$ at very high spectral resolution. Essential parameters determining the u...
Temperature (in)dependence of the Casimir-Polder potential of a particle near a metallic sphere
Casimir-Polder potential particle metallic sphere Temperature independence
2011/8/16
Abstract: It has recently been shown that the Casimir-Polder potential of a particle in an energy eigenstate near a conducting body can be virtually temperature independent, provided the separation be...
Mathematical model for positive feedback and temperature induced signal transduction and differential gene regulation in {\it Bordetella pertussis}}
Mathematical model positive feedback temperature induced signal
2011/9/9
Based on the phosphorelay kinetics operative within BvgAS two component system we propose a mathematical model for signal transduction and differential gene regulation in Bordetella pertussis. To unde...
Towards the N_f=2 deconfinement transition temperature with O(a) improved Wilson fermions: An update
Lattice QCD Quark-gluon plasma Deconfinement Phase transitions
2011/1/14
We give an update on our current project to determine the transition temperature and the order of the deconfinement transition in the chiral limit of two flavour QCD. We use nonperturbatively O(a) imp...
Dynamic Characteristics of the Low-Temperature Decomposition of the C20 Fullerene
the Low-Temperature Decomposition the C20 Fullerene
2010/11/17
A novel algorithm has been proposed for simulating thermal decomposition of atomic clusters at such low temperatures that the corresponding lifetimes are macroscopic and, hence, standard molecular dy...
Low-temperature thermodynamics of the unitary Fermi gas: superfluid fraction, first sound and second sound
Low-temperature thermodynamics unitary Fermi gas superfluid fraction
2010/11/25
We investigate the low-temperature thermodynamics of the unitary Fermi gas by introducing a
model based on the zero-temperature spectra of both bosonic collective modes and fermonic singleparticle ex...
Temperature Dependent Structure of Low Index Copper Surfaces Studied by Molecular Dynamics Simulation
Temperature Dependent Structure Low Index Copper Surfaces Molecular Dynamics Simulation
2010/10/19
The thermal behavior of the (010), (110) and (111) copper surfaces is studied by molecular dynamics simulation. We have used a many-body potential based on the tight-binding model in order to describe...

Incident-Energy Dependence the Effective Temperature Heavy-Ion Collisions
2010/10/19
We study, in a hydrodynamical approach, the energy dependence of the kaon mT spectra in central Pb+Pb (Au+Au) collisions. We show that the experimental data of the inverse slope parameter can be repro...
