Fundamentals of Nano-Thermodynamics
M. Hartmann, G. Mahler, O. Hess
Recent progress in the synthesis and processing of nano-structured materials and systems calls for an improved understanding of thermal properties on small length scales. In this c…
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…
