Testing Nonclassicality and Non-Gaussianity in Phase Space
Nonclassicality Non-Gaussianity Phase Space
2016/1/22
We theoretically propose and experimentally demonstrate a nonclassicality test of a single-mode field in phase space, which has an analogy with the nonlocality test proposed by Banaszek and Wódkiewicz...
Experimental phase-space-based optical amplification of scar modes
Experimental phase-space-based optical amplification scar modes Optics
2012/4/20
Waves billiard which are chaotic in the geometrical limit are known to support non-generic spatially localized modes called scar modes. The interaction of the scar modes with gain has been recently in...
Solitons in Maximally Entangled Two Qubit Phase Space
Maximally Entangled Two Qubit Phase Space Quantum Physics
2011/9/29
Abstract: Motivated by M\"obius transformation for symmetrical points under the generalized circle in complex plane, the system of symmetrical spin coherent states corresponding to antipodal qubit sta...
The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its phase dilemma. The c...
Forty-five years after the point de d\'epart [1] of density functional theory, its applications in chemistry and the study of electronic structures keep steadily growing. However, the precise form of...
Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy
Static isolated horizons invariant phase space quantization black hole entropy
2010/12/20
We study the classical field theoretical formulation of static generic isolated horizons in a man-ifestly SU(2) invariant formulation. We show that the usual classical description requires revision in...
Phase space barriers and dividing surfaces in the absence of critical points of the potential energy
Phase space dividing surfaces critical points the potential energy
2010/11/12
We consider the existence of invariant manifolds in phase space governing reaction dynamics in situations where there are no saddle points on the potential energy surface in the relevant regions of co...
Recent research has revealed several different techniques for nanoscopic gas nucleation on submerged surfaces, with findings seemingly in contradiction with each other. In response to this, we have s...
Tunable subpicosecond electron bunch train generation using a transverse-to-longitudinal phase space exchange technique
Tunable subpicosecond electron bunch train generation transverse-to-longitudinal phase space
2010/11/16
We report on the experimental generation of a train of subpicosecond electron bunches. The bunch train generation is accomplished using a beamline capable of exchanging the coordinates between the hor...
Phase space spinor amplitudes for spin 1/2 systems
Phase space spinor amplitudes spin 1/2 systems
2010/11/5
The concept of phase space amplitudes for systems with continuous degrees of freedom is generalized to finite-dimensional spin systems. Complex amplitudes are obtained on both a sphere and a finite la...
Nonlinear Landau-Zener tunneling in quantum phase space
Nonlinear tunneling quantum phase space
2010/10/29
We present a detailed analysis of the Landau-Zener problem for an interacting Bose-Einstein condensate in a time-varying double-well trap, especially focussing on the relation between the full many-p...
We show that the phase shift of 2 is crucial for the phase space translation covariance of the measured high-amplitude limit observable in eight-port homodyne detection. However, for an arbitrary pha...
Phase-space characterization of complexity in quantum many-body dynamics
Phase-space characterization complexity quantum many-body dynamics
2010/10/18
We propose a phase-space Wigner harmonics entropy measure for many-body quantum dynamical
complexity. This measure, which reduces to the well known measure of complexity in classical
systems and whi...

2010/10/21
The paper review and develop the alternative formulation of quantum mechanics known as the phase space quantum mechanics or deformation quantization. It is shown that the quantization naturally arises...
The semiclassical formula for the coherent-state propagator is written in terms of complex classical trajectories of an equivalent classical system. Depending on the parameters involved, more than one...
