Experimental determination of a nonclassical Glauber-Sudarshan P function
T. Kiesel, W. Vogel, V. Parigi +2
A quantum state is nonclassical if its Glauber-Sudarshan P function fails to be interpreted as a probability density. This quantity is often highly singular, so that its reconstruc…
Towards quantum frequency combs: boosting the generation of highly nonclassical light states by cavity-enhanced parametric down-conversion at high repetition rates
Alessandro Zavatta, Valentina Parigi, Marco Bellini
We demonstrate the generation of multi-photon quantum states of light by cavity-enhanced parametric down-conversion in the high-repetition-rate pulsed regime. An external enhanceme…
Quantum decoherence reduction by increasing the thermal bath temperature
A. Montina, F. T. Arecchi
The well-known increase of the decoherence rate with the temperature, for a quantum system coupled to a linear thermal bath, holds no longer for a different bath dynamics. This is…
Spinning Particle with Anomalous Magnetic Moment in an External Plane Wave Field
A. Barducci, R. Giachetti
In this paper we study the interaction of a Dirac-Pauli particle with an electromagnetic plane wave, by using a previously given generalization of the pseudo-classical Lagrangian f…
