Abstract: We report on residual gas damping of the motion of a macroscopic test mass enclosed in a nearby housing in the molecular flow regime. The damping coefficient, and thus the associated thermal...
Fluid dynamics and noise in bacterial cell-cell and cell-surface scattering
Fluid dynamics noise bacterial cell-cell cell-surface scattering
2011/8/4
Abstract: Bacterial processes ranging from gene expression to motility and biofilm formation are constantly challenged by internal and external noise. While the importance of stochastic fluctuations h...
The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine state in which the atoms...
Laser phase noise effects on the dynamics of optomechanical resonators
optomechanical resonators laser phase noise Quantum Physics
2010/11/8
We investigate theoretically the influence of laser phase noise on the cooling and heating of a generic cavity optomechanical system. We derive the back-action damping and heating rates and the mechan...
Noise resilient quantum interface based on QND interaction
quantum interface Noise resilient quantum-non-demolition interactions
2010/3/10
We propose a quantum interface protocol based on two quantum-non-demolition interactions (QND) arranged either in sequence or in parallel. Since the QND coupling arises naturally in interactions betwe...
Capacities of lossy bosonic channel with correlated noise
lossy bosonic channel correlated noise
2010/4/12
We evaluate the information capacities of a lossy bosonic channel with correlated noise. The model generalizes the one recently discussed in [Phys. Rev. A 77, 052324 (2008)], where memory effects come...
Highly efficient energy excitation transfer in light-harvesting complexes: The fundamental role of noise-assisted transport
energy excitation light-harvesting complexes undamental role of noise-assisted transport
2010/4/9
Excitation transfer through interacting systems plays an important role in many areas of physics, chemistry, and biology. The uncontrollable interaction of the transmission network with a noisy enviro...
Noise effects in a three-player Prisoner's Dilemma quantum game
Prisoner＇s Dilemma Three-player Decoherenc Correlated Noise Dephasing Channel
2010/4/8
We study the three-player Prisoner's Dilemma game under the effect of decoherence and correlated noise. It is seen that the quantum player is always better off over the classical players. It is also s...
Non-commuting noises may give rise to entanglement sudden death. By considering the decoherence dynamics during establishment of the channel states and noisy recovery operations, we study further the ...
