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…
Influence of classical resonances on chaotic tunnelling
Amaury Mouchet, Christopher Eltschka, Peter Schlagheck
Dynamical tunnelling between symmetry-related stable modes is studied in the periodically driven pendulum. We present strong evidence that the tunnelling process is governed by non…
Resonance-assisted decay of nondispersive wave packets
Sandro Wimberger, Peter Schlagheck, Christopher Eltschka +1
We present a quantitative semiclassical theory for the decay of nondispersive electronic wave packets in driven, ionizing Rydberg systems. Statistically robust quantities are extra…
Resonance- and chaos-assisted tunneling in mixed regular-chaotic systems
Christopher Eltschka, Peter Schlagheck
We present evidence that nonlinear resonances govern the tunneling process between symmetry-related islands of regular motion in mixed regular-chaotic systems.In a similar way as f…
