Continuous photometric observations at ENEA base in Lampedusa to estimate precipitable water
water-vapour aerosols GPS sunphotometer NWP-model
2015/9/16
Water vapour is a variable component of the atmosphere both in space and time. It is one of the most important
components because of its effects in many fi elds: Meteorology, Climatology, Remote Sens...
Exact, complete, and universal continuous-time worldline Monte Carlo approach to the statistics of discrete quantum systems
Quantum monte carlo procedures discretization discrete Hilbert space green's function
2014/12/22
We show how the worldline quantum Monte Carlo procedure, which usually relies on an artificial time discretization, can be formulated directly in continuous time, rendering the scheme exact. For an ar...
Worm Algorithm for Continuous-Space Path Integral Monte Carlo Simulations
Integral monte carlo method the worm simulation lattice model the continuous spatial multibody system thermodynamics
2014/12/20
We present a new approach to path integral Monte Carlo (PIMC) simulations based on the worm algorithm, originally developed for lattice models and extended here to continuous-space many-body systems. ...

In this letter it is demonstrated that Bell's correlation can be ambiguous for continuously distributed local hidden variables.
Generation of continuous-variable quadripartite square cluster state and its entanglement improvement via quantum feedback
quantum optics continuous variable cluster state feedback
2011/12/15
In this paper, we investigate the generation of continuous-variable quadripartite square cluster state of optical fields and discuss the enhancement of the multipartite entanglement of the cluster sta...
Resolutions of identity for some non-Hermitian Hamiltonians I: exceptional point in continuous spectrum

2011/9/23
Abstract: Resolutions of identity for certain non-Hermitian Hamiltonians constructed from biorthogonal sets of their eigen- and associated functions are given for the spectral problem defined on entir...
Absolutely continuous spectrum of a one-paramentric family of Schrodinger operators
one-paramentric family Schrodinger operators Spectral Theory
2011/7/27
Abstract: We consider a family of operators $-\Delta+ t V$ with a slowly decaying and oscillating potential $V$. We prove that the absolutely continuous spectrum of this operator is essentially suppor...
Simulating quantum statistics with entangled photons: a continuous transition from bosons to fermions
quantum statistics entangled photons bosons fermions
2011/9/9
In contrast to classical physics, quantum mechanics divides particles into two classes|bosons and fermions|whose exchange statistics dictate the dynamics of systems at a fundamental level . In two dim...
Cross-Kerr nonlinearity between continuous-mode coherent states and single photons
Cross-Kerr nonlinearity continuous-mode coherent states single photons
2013/7/3
Weak cross-Kerr nonlinearities between single photons and coherent states are the basis for many applications in quantum-information processing. These nonlinearities have so far mainly been discussed ...

2010/11/23
In systems with a spontaneously broken continuous symmetry, the perturbative loop expansion
is plagued with infrared divergences due to the coupling between transverse and longitudinal fluctuations.A...

2010/11/8
We address continuous variable quantum key distribution (QKD) in non-Markovian lossy channels and show how the non-Markovian features may be exploited to enhance security and/or to detect the presence...
