Dimensional Crossover of the Dephasing Time in Disordered Mesoscopic Rings: From Diffusive through Ergodic to 0D Behavior
M. Treiber, O. M. Yevtushenko, F. Marquardt +2
We analyze dephasing by electron interactions in a small disordered quasi-one dimensional (1D) ring weakly coupled to leads, where we recently predicted a crossover for the dephasi…
Single-Atom Cavity QED and Opto-Micromechanics
M. Wallquist, K. Hammerer, P. Zoller +6
In a recent publication [K. Hammerer et al., Phys. Rev. Lett. 103, 063005 (2009)] we have shown the possibility to achieve strong coupling of the quantized motion of a micron-sized…
Entanglement of mechanical oscillators coupled to a non-equilibrium environment
Max Ludwig, K. Hammerer, Florian Marquardt
Recent experiments aim at cooling nanomechanical resonators to the ground state by coupling them to non-equilibrium environments in order to observe quantum effects such as entangl…
Dimensional Crossover of the Dephasing Time in Disordered Mesoscopic Rings
M. Treiber, O. M. Yevtushenko, F. Marquardt +2
We study dephasing by electron interactions in a small disordered quasi-one dimensional (1D) ring weakly coupled to leads. We use an influence functional for quantum Nyquist noise…
Strong coupling of a mechanical oscillator and a single atom
K. Hammerer, M. Wallquist, C. Genes +6
We propose and analyze a setup to achieve strong coupling between a single trapped atom and a mechanical oscillator. The interaction between the motion of the atom and the mechanic…
Mesoscopic Spin-Boson Models of Trapped Ions
D. Porras, F. Marquardt, J. von Delft +1
Trapped ions arranged in Coulomb crystals provide us with the elements to study the physics of a single spin coupled to a boson bath. In this work we show that optical forces allow…
