We study many-body tunneling of a small Bose-Einstein condensate in a periodically modulated, tilted double-well potential. Periodic modulation of the trapping potential leads to an analog ofâ€¦ (More)

We present measurements of the near-field heat transfer between the tip of a thermal profiler and planar material surfaces under ultrahigh vacuum conditions. For tip-sample distances below 10(-8) m,â€¦ (More)

We present numerical solutions to the extended Doeringâ€“Constantin variational principle for upper bounds on the energy dissipation rate in turbulent plane Couette flow. Using the compound matrixâ€¦ (More)

We question the validity of the grand canonical ensemble for the description of Boseâ€“Einstein condensation of small ideal Bose gas samples in isolated harmonic traps. While the ground state fractionâ€¦ (More)

We study coherent dynamics of tight-binding systems interacting with static and oscillating external fields. We consider Bloch oscillations and WannierStark localization caused by dc fields, andâ€¦ (More)

The problem of radiative heat transfer between two dielectric bodies is analyzed from the point of view of elementary quantum electrodynamics. The dielectric properties of the bodies are assumed toâ€¦ (More)

The number partitioning problem can be interpreted physically in terms of a thermally isolated non-interacting Bose gas trapped in a one-dimensional harmonic oscillator potential. We exploit thisâ€¦ (More)

The application of the conventional saddle-point approximation to condensed Bose gases is thwarted by the approach of the saddle-point to the groundstate singularity of the grand canonical partitionâ€¦ (More)

We investigate the probability distribution that governs the number of ground-state particles in a partially condensed ideal Bose gas confined to a cubic volume within the canonical ensemble.â€¦ (More)

The effect of calcium phosphate-based microchannels on the growth and orientation of human osteoblast cells is investigated in this study. As substrates, hydroxyapatite-based microchannels with highâ€¦ (More)
