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…

Quantum Maxwell-Bloch equations for spontaneous emission in optical semiconductor devices
Ortwin Hess, Holger F. Hofmann
We present quantum Maxwell-Bloch equations (QMBE) for spatially inhomogeneous optical semiconductor devices taking into account the quantum noise effects which cause spontaneous em…

Quantum control of atomic systems by time-resolved homodyne detection of spontaneous emission
Holger F. Hofmann, Ortwin Hess, Guenter Mahler
We describe the light-matter interaction of a single two level atom with the electromagnetic vacuum in terms of field and dipole variables by considering homodyne detection of the…
