Light-shift-induced photonic nonlinearities
Fernando G. S. L. Brandao, Michael J. Hartmann, Martin B. Plenio
We propose a new method to produce self- and cross-Kerr photonic nonlinearities, using light-induced Stark shifts due to the interaction of a cavity mode with atoms. The proposed e…
Quantum phase transitions with Photons and Polaritons
Fernando G. S. L. Brandao, Michael J. Hartmann, Martin B. Plenio
We show that a system of polaritons - combined atom and photon excitations - in an array of coupled cavities, under an experimental set-up usually considered in electromagnetically…
Existence of temperature on the nanoscale
Michael Hartmann, Guenter Mahler, Ortwin Hess
We consider a regular chain of quantum particles with nearest neighbour interactions in a canonical state with temperature . We analyse the conditions under which the state fact…
