Use of Lambert's Theorem for the n-Dimensional Coulomb Problem
Vassiliki Kanellopoulos, Manfred Kleber, Tobias Kramer
We present the analytical solution in closed form for the semiclassical limit of the quantum mechanical Coulomb Green function in position space in n dimensions. We utilize a proje…
Quasiperiodic propagation in time of some classical/quantum systems: Nielsen's conserved quantity and Floquet properties
Peter Kramer, Tobias Kramer, Vladimir I. Man'ko
We consider classical and quantum propagators for two different time intervals. If these propagators follow one another in a Fibonacci sequence we get a discrete quasiperiodic syst…
Dissipative dynamics of a biased qubit coupled to a harmonic oscillator: Analytical results beyond the rotating wave approximation
Johannes Hausinger, Milena Grifoni
We study the dissipative dynamics of a biased two-level system (TLS) coupled to a harmonic oscillator (HO), the latter interacting with an Ohmic environment. Using Van-Vleck pertur…
Decoherence, Entanglement and Irreversibility in Quantum Dynamical Systems with Few Degrees of Freedom
Ph. Jacquod, C. Petitjean
This review summarizes and amplifies on recent investigations of coupled quantum dynamical systems in the short wavelength limit. We formulate and attempt to answer three fundament…
Three-tangle for mixtures of generalized GHZ and generalized W states
Christopher Eltschka, Andreas Osterloh, Jens Siewert +1
We give a complete solution for the three-tangle of mixed three-qubit states composed of a generalized GHZ state, a|000>+b|111>, and a generalized W state, c|001>+d|010>+f|100>. Us…
Tangles of superpositions and the convex-roof extension
Andreas Osterloh, Jens Siewert, Armin Uhlmann
We discuss aspects of the convex-roof extension of multipartite entanglement measures, that is, $SL(2,\CC)$ invariant tangles. We highlight two key concepts that contain valuable i…
