Optimal control of time-dependent targets
I. Serban, J. Werschnik, E. K. U. Gross
In this work, we investigate how and to which extent a quantum system can be driven along a prescribed path in Hilbert space by a suitably shaped laser pulse. To calculate the opti…

Path Integral Approach to 't Hooft's Derivation of Quantum from Classical Physics
Massimo Blasone, Petr Jizba, Hagen Kleinert
We present a path-integral formulation of 't Hooft's derivation of quantum from classical physics. The crucial ingredient of this formulation is Gozzi et al.'s supersymmetric path…

Recursive Calculation of Effective Potential and Variational Resummation
Sebastian F. Brandt, Hagen Kleinert, Axel Pelster
We set up a method for a recursive calculation of the effective potential which is applied to a cubic potential with imaginary coupling. The result is resummed using variational pe…
