The structure of the population inside the propagating front
Branch diffusion process of single particle particle
2015/9/25
We investigate the long-time and long-range behavior of branching diffusion processes (starting with a single particle) in two different situations: when the
branching potential has compact support a...
Tailoring population inversion in Landau-Zener-Stuckelberg interferometry of flux qubits
Tailoring population inversion Landau-Zener-Stuckelberg interferometry flux qubits
2012/2/27
We distinguish different mechanisms for population inversion in flux qubits driven by dc+ac magnetic fields. We show that for driving amplitudes such that there are Landau-Zener-St\"uckelberg interefe...
Population redistribution in optically trapped polar molecules
Population redistribution polar molecules Atomic Physics
2011/8/3
Abstract: We investigate the rovibrational population redistribution of polar molecules in the electronic ground state induced by spontaneous emission and blackbody radiation. As a model system we use...
Nuclear coherent population transfer with x-ray laser pulses
Nuclear coherent population transfer x-ray laser pulses
2010/12/27
Coherent population transfer in a nuclear three-level system via stimulated Raman adiabatic passage is studied. To compensate for the lack of $\gamma$-ray laser sources, we envisage accelerated nucle...
Population imbalance and pairing in the BCS-BEC crossover of three-component ultracold fermions
Population imbalance three-component ultracold fermions
2010/11/17
We investigate the phase diagram and the BCS-BEC crossover of a homogeneous three-component
ultracold Fermi gas with a U(3) invariant attractive interaction. We show that the system at
sufficiently ...
We study a complementarity game as a systematic tool for the investigation of the interplay between individual optimization and population effects and for the comparison of different strategy and lea...
The tragedy of the commons in a multi-population complementarity game
multi-population complementarity game Populations and Evolution
2010/11/18
We study a complementarity game with multiple populations whose members' offered contributions are put together towards some common aim. When the sum of the players' offers reaches or exceeds some th...
DC-switchable and single-nanocrystal-addressable coherent population transfer
DC-switchable single-nanocrystal-addressable coherent population transfer
2010/10/21
Achieving coherent population transfer in the solid-state is challenging compared to atomic systems due to closely spaced electronic states and fast decoherence. Here, within an atomistic pseudopotent...
First experience in operating the population of the condition databases for the CMS experiment
CMS experiment condition data
2010/3/15
Reliable population of the condition databases is critical for the correct operation of the online selection as well as of the offline reconstruction and analysis of data. We will describe here the sy...
Quantum phase diagram of fermion mixtures with population imbalance in one-dimensional optical lattices
Quantum phase diagram of fermion population imbalance one-dimensional optical lattices
2010/4/12
With a recently developed time evolving block decimation (TEBD) algorithm, we numerically study the ground state quantum phase diagram of fermi mixtures with attractive inter-species interactions load...
