Quantum Many-Body Phenomena in Coupled Cavity Arrays
Michael J. Hartmann, Fernando G. S. L. Brandao, Martin B. Plenio
The increasing level of experimental control over atomic and optical systems gained in the past years have paved the way for the exploration of new physical regimes in quantum opti…
Density Matrix Renormalization Group in the Heisenberg Picture
Michael J. Hartmann, Javier Prior, Stephen R. Clark +1
In some cases the state of a quantum system with a large number of subsystems can be approximated efficiently by the density matrix renormalization group, which makes use of redund…
Steady state entanglement in the mechanical vibrations of two dielectric membranes
Michael J. Hartmann, Martin B. Plenio
We consider two dielectric membranes suspended inside a Fabry-Perot-cavity, which are cooled to a steady state via a drive by suitable classical lasers. We show that the vibrations…
