Infinite Switch Simulated Tempering in Force (FISST)
Michael J. Hartmann, Yuvraj Singh, Eric Vanden-Eijnden +1
Many proteins in cells are capable of sensing and responding to piconewton scale forces, a regime in which conformational changes are small but significant for biological processes…
Minimal length scales for the existence of local temperature
Michael J Hartmann
We review a recent approach to determine the minimal spatial length scales on which local temperature exists. After mentioning an experiment where such considerations are of releva…
Global and local relaxation of a spin-chain under exact Schroedinger and master-equation dynamics
Markus J. Henrich, Mathias Michel, Michael Hartmann +2
We solve the Schroedinger equation for an interacting spin-chain locally coupled to a quantum environment with a specific degeneracy structure. The reduced dynamics of the whole sp…
On Which Length Scales Can Temperature Exist in Quantum Systems?
Michael Hartmann, Guenter Mahler, Ortwin Hess
We consider a regular chain of elementary quantum systems with nearest neighbor interactions and assume that the total system is in a canonical state with temperature . We analy…
Measurable Consequences of the Local Breakdown of the Concept of Temperature
Michael Hartmann, Guenther Mahler
Local temperature defined by a local canonical state of the respective subsystem, does not always exist in quantum many body systems. Here, we give some examples of how this breakd…
Spectral densities and partition functions of modular quantum systems as derived from a central limit theorem
Michael Hartmann, Guenter Mahler, Ortwin Hess
Using a central limit theorem for arrays of interacting quantum systems, we give analytical expressions for the density of states and the partition function at finite temperature o…
