Holey Random Walks: Optics of Heterogeneous Turbid Composites
Tomas Svensson, Kevin Vynck, Marco Grisi +3
We present a probabilistic theory of random walks in turbid media with non-scattering regions. It is shown that important characteristics such as diffusion constants, average step…
A novel technique for single-shot energy-resolved 2D X-ray imaging of plasmas relevant for the Inertial Confinement Fusion
L. Labate, P. Koester, T. Levato +1
A novel X-ray diagnostic of laser-fusion plasmas is described, allowing 2D monochromatic images of hot, dense plasmas to be obtained in any X-ray photon energy range, over a large…
A Multi-path Interferometer with Ultracold Atoms Trapped in an Optical Lattice
J. Chwedenczuk, F. Piazza, A. Smerzi
We study an ultra-cold gas of bosons trapped in a one dimensional -site optical lattice perturbed by a spatially dependent potential , where the unknown coupling…
Dynamics of self-generated, large amplitude magnetic fields following high-intensity laser matter interaction
G. Sarri, A. Macchi, C. A. Cecchetti +15
The dynamics of magnetic fields with amplitude of several tens of Megagauss, generated at both sides of a solid target irradiated with a high intensity (? 1019W/cm2) picosecond las…
Tomographic characterisation of correlations in a photonic tripartite state
A. Chiuri, L. Mazzola, M. Paternostro +1
Starting from a four-partite photonic hyper-entangled Dicke resource, we report the full tomographic characterization of three-, two-, and one-qubit states obtained by projecting o…
Experimental implementation of a Kochen-Specker set of quantum tests
Vincenzo D'Ambrosio, Isabelle Herbauts, Elias Amselem +4
The conflict between classical and quantum physics can be identified through a series of yes-no tests on quantum systems, without it being necessary that these systems be in specia…
TeraHz tuning of whispering gallery modes in a PDMS, stand-alone, stretchable microsphere
Ramgopal Madugani, Yong Yang, Jonathan M Ward +7
We report on tuning the optical whispering gallery modes in a poly dimethyl siloxane-based (PDMS) microsphere resonator by more than a THz. The PDMS microsphere system consists of…
Linear Optics Simulation of Non-Markovian Quantum Dynamics
Andrea Chiuri, Chiara Greganti, Laura Mazzola +2
The simulation of quantum processes is a key goal for the grand programme aiming at grounding quantum technologies as the way to explore complex phenomena that are inaccessible thr…
Direct evaporative cooling of 39K atoms to Bose-Einstein condensation
Manuele Landini, Sanjukta Roy, Giacomo Roati +4
We report the realization of Bose-Einstein condensates of 39K atoms without the aid of an additional atomic coolant. Our route to Bose-Einstein condensation comprises Sub Doppler l…
Ion acceleration in multispecies targets driven by intense laser radiation pressure
S. Kar, K. F. Kakolee, B. Qiao +15
The acceleration of ions from ultra-thin foils has been investigated using 250 TW, sub-ps laser pulses, focused on target at intensities up to $3\times10^{20} \Wcm2$. The ion spect…
Experimental achievement of the entanglement assisted capacity for the depolarizing channel
Andrea Chiuri, Sandro Giacomini, Chiara Macchiavello +1
We experimentally demonstrate the achievement of the entanglement assisted capacity for classical information transmission over a depolarizing channel. The implementation is based…
Metallo-dielectric hybrid antennas for ultrastrong enhancement of spontaneous emission
Xue-Wen Chen, Mario Agio, Vahid Sandoghdar
We devise new optical antennas that reduce the excited-state radiative lifetimes of emitters to the order of 100 femtoseconds while maintaining quantum efficiencies of about 80% at…
Twin matter waves for interferometry beyond the classical limit
Bernd Lücke, Manuel Scherer, Jens Kruse +10
Interferometers with atomic ensembles constitute an integral part of modern precision metrology. However, these interferometers are fundamentally restricted by the shot noise limit…
Engineering a C-Phase quantum gate: optical design and experimental realization
Andrea Chiuri, Chiara Greganti, Paolo Mataloni
A two qubit quantum gate, namely the C-Phase, has been realized by exploiting the longitudinal momentum (i.e. the optical path) degree of freedom of a single photon. The experiment…
Frequency metrology of helium around 1083 nm and determination of the nuclear charge radius
P. Cancio Pastor, L. Consolino, G. Giusfredi +4
We measure the absolute frequency of seven out of the nine allowed transitions between the 2{\it S} and 2{\it P} hyperfine manifolds in a metastable He beam by using an…
Quantum electrodynamic calculation of the hyperfine structure of 3He
K. Pachucki, V. A. Yerokhin, P. Cancio Pastor
The combined fine and hyperfine structure of the states in He is calculated within the framework of nonrelativistic quantum electrodynamics. The calculation accounts for…
