Collectivity-assisted ground state cooling of a nanomechanical resonator
K. Xia, J. Evers
We discuss cooling of a nanomechanical resonator to its mechanical ground state by coupling it to a collective system of two interacting flux qubits. We find that the collectivity…
Spontaneous emission interference in negative-refractive-index waveguides
G. X. Li, J. Evers, C. H. Keitel
The spontaneous decay of a V-type three-level atom placed in a negative-refractive-index waveguide is analyzed. We find that in thin waveguides, highly efficient surface guided mod…
Phase modulation induced by cooperative effects in electromagnetically induced transparency
R. Fleischhaker, T. N. Dey, J. Evers
We analyze the influence of dipole-dipole interactions in an electromagnetically induced transparency setup at high density. We show both analytically and numerically that the pola…
Sub-wavelength position measurements with running wave driving fields
J. Evers, S. Qamar
A scheme for sub-wavelength position measurements of quantum particles is discussed, which operates with running-wave laser fields as opposed to standing wave fields proposed in pr…
