Molecular dynamics investigations on a quantum system in a thermostat | | J. Schnack
; | | Date: |
16 Dec 1997 | | Journal: | Physica A 259 (1998) 49-58 | | Subject: | Statistical Mechanics | cond-mat.stat-mech | | Affiliation: | U. of Osnabrueck | | Abstract: | The model quantum system of fermions in a one dimensional harmonic oscillator potential is investigated by a molecular dynamics method at constant temperature. Although in quantum mechanics the equipartition theorem cannot be used like in the Nose-Hoover-thermostat it is possible to couple an additional degree of freedom to the system which acts as a thermometer and drives the system towards the desired temperature via complex time steps. | | Source: | arXiv, cond-mat/9712188 | | Services: | Forum | Review | PDF | Favorites | |
