Quantum Performance of Thermal Machines over Many Cycles
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +1
The performance of quantum heat engines is generally based on the analysis of a single cycle. We challenge this approach by showing that the total work performed by a quantum engin…
Non-destructive monitoring of Bloch oscillations in an optical cavity
H. Keßler, J. Klinder, B. P. Venkatesh +2
Bloch oscillations are a hallmark of coherent wave dynamics in periodic potentials. They occur as the response of quantum mechanical particles in a lattice if a weak force is appli…
Nonlinear Phenomena of Ultracold Atomic Gases in Optical Lattices: Emergence of Novel Features in Extended States
Gentaro Watanabe, B. Prasanna Venkatesh, Raka Dasgupta
The system of a cold atomic gas in an optical lattice is governed by two factors: nonlinearity originating from the interparticle interaction, and the periodicity of the system set…
Attraction-induced dynamical stability of a Bose-Einstein condensate in a nonlinear lattice
Raka Dasgupta, B. Prasanna Venkatesh, Gentaro Watanabe
We study multiple-period Bloch states of a Bose-Einstein condensate with spatially periodic interactomic interaction. Solving the Gross-Pitaevskii equation for the continuum model,…
On-chip quantum interference of a superconducting microsphere
H. Pino, J. Prat-Camps, K. Sinha +2
We propose and analyze an all-magnetic scheme to perform a Young's double slit experiment with a micron-sized superconducting sphere of mass amu. We show that i…
