Stochastic thermodynamics of a finite quantum system coupled to a heat bath
Heinz-Jürgen Schmidt, Jürgen Schnack, Jochen Gemmer
We consider a situation where an -level system (NLS) is coupled to a heat bath without being necessarily thermalized. For this situation we derive general Jarzinski-type equatio…
Theoretical formation of carbon nanomembranes under realistic conditions using classical molecular dynamics
J. Ehrens, F. Gayk, P. Vorndamme +6
Carbon nanomembranes made from aromatic precursor molecules are free standing nanometer thin materials of macroscopic lateral dimensions. Although produced in various versions for…
Rotational magnetocaloric effect of anisotropic giant spin systems
C. Beckmann, J. Ehrens, J. Schnack
The magnetocaloric effect, that consists of adiabatic temperature changes in a varying external magnetic field, appears not only when the amplitude is changed, but in cases of anis…
Classical molecular dynamics investigations of biphenyl-based carbon nano membranes
A. Mrugalla, J. Schnack
Free-standing carbon nanomembranes (CNM) with molecular thickness and macroscopic size are fascinating objects both for fundamental reasons and for applications in nanotechnology.…
Optimized implementation of the Lanczos method for magnetic systems
J. Schnack, P. Hage, H. -J. Schmidt
Numerically exact investigations of interacting spin systems provide a major tool for an understanding of their magnetic properties. For medium size systems the approximate Lanczos…
