Damped collective motion of many body systems: A variational approach to the quantal decay rate
Christian Rummel, Helmut Hofmann
We address the problem of collective motion across a barrier like encountered in fission. A formula for the quantal decay rate is derived which bases on a recently developed variat…
A variational approach to the partition function of an interacting many body system
Christian Rummel, Helmut Hofmann
For the calculation of the partition function of small, isolated and interacting many body systems an improvement with respect to previous formulations is presented.…
Damped collective motion of isolated many body systems within a variational approach to functional integrals
Christian Rummel, Helmut Hofmann
Two improvements with respect to previous formulations are presented for the calculation of the partition function of small, isolated and interacting many body system…
Nuclear quantum transport for barrier problems
Christian Rummel, Helmut Hofmann
A method is presented which allows one to introduce collective coordinates self-consistently, in distinction to the Caldeira-Leggett model. It is demonstrated how the partition fun…
Influence of microscopic transport coefficients on the formation probabilities for super-heavy elements
Christian Rummel, Helmut Hofmann
The formation probability is shown to increase by a few orders of magnitude if microscopic transport coefficients are used rather than those of the common macroscopic pictures. Qua…
Self-consistent quantal treatment of decay rates within the perturbed static path approximation
C. Rummel, H. Hofmann
The framework of the Perturbed Static Path Approximation (PSPA) is used to calculate the partition function of a finite Fermi system from a Hamiltonian with a separable two body in…
