Gibbs States and the Set of Solutions of Random Constraint Satisfaction Problems
Florent Krzakala, Andrea Montanari, Federico Ricci-Tersenghi +2
An instance of a random constraint satisfaction problem defines a random subset S (the set of solutions) of a large product space (the set of assignments). We consider two prototyp…
Spectroscopic evidences of quantum critical charge fluctuations in cuprates
M. Grilli, S. Caprara, C. Di Castro +1
We calculate the optical conductivity in a clean system of quasiparticles coupled to charge-ordering collective modes. The absorption induced by these modes may produce an anomalou…
Information-Disturbance Tradeoff in Quantum State Discrimination
Francesco Buscemi, Massimiliano F. Sacchi
When discriminating between two pure quantum states, there exists a quantitative tradeoff between the information retrieved by the measurement and the disturbance caused on the unk…
Phase behavior of polydisperse sticky hard spheres: analytical solutions and perturbation theory
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni
We discuss phase coexistence of polydisperse colloidal suspensions in the presence of adhesion forces. The combined effect of polydispersity and Baxter's sticky-hard-sphere (SHS) p…
Multicomponent adhesive hard sphere models and short-ranged attractive interactions in colloidal or micellar solutions
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni +1
We investigate the dependence of the stickiness parameters -- where the are the conventional Baxter parameters -- on the solute diameters and…
Entanglement of electrons in interacting molecules
Tina A. C. Maiolo, Fabio Della Sala, Luigi Martina +1
Quantum entanglement is a concept commonly used with reference to the existence of certain correlations in quantum systems that have no classical interpretation. It is a useful res…
Information-disturbance tradeoff for spin coherent state estimation
Massimiliano F. Sacchi
We show how to quantify the optimal tradeoff between the amount of information retrieved by a quantum measurement in estimating an unknown spin coherent state and the disturbance o…
Screening effects in Coulomb frustrated phase separation
C. Ortix, J. Lorenzana, M. Beccaria +1
We solve a model of phase separation among two competing phases frustrated by the long-range Coulomb interaction in two and three dimensions (2D/3D) taking into account finite comp…
One-Particle Anomalous Excitations of Gutzwiller Projected BCS Superconductors and Bogoliubov Quasi-Particle Characteristics
Seiji Yunoki
Low-lying one-particle anomalous excitations are studied for Gutzwiller projected strongly correlated BCS states. It is found that the one-particle anomalous excitations are highly…
Microwave Irradiation Effects on Random Telegraph Signal in a MOSFET
Enrico Prati, Marco Fanciulli, Alessandro Calderoni +2
We report on the change of the characteristic times of the random telegraph signal (RTS) in a MOSFET operated under microwave irradiation up to 40 GHz as the microwave field power…
Superbroadcasting of harmonic oscillators mixed states
G. M. D'Ariano, P. Perinotti, M. F. Sacchi
We consider the problem of broadcasting quantum information encoded in the displacement parameter for an harmonic oscillator, from N to M>N copies of a thermal state. We show the W…
The Quantum Cocktail Party
G. M. D'Ariano, R. Demkowicz-Dobrzanski, P. Perinotti +1
We consider the problem of decorrelating states of coupled quantum systems. The decorrelation can be seen as separation of quantum signals, in analogy to the classical problem of s…
Complete and Deterministic discrimination of polarization Bell state assisted by momentum entanglement
M. Barbieri, G. Vallone, P. Mataloni +1
A complete and deterministic Bell state measurement was realized by a simple linear optics experimental scheme which adopts 2-photon polarization-momentum hyperentanglement. The sc…
Optical state engineering, quantum communication, and robustness of entanglement promiscuity in three-mode Gaussian states
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We present a novel, detailed study on the usefulness of three-mode Gaussian states states for realistic processing of continuous-variable quantum information, with a particular emp…
Phase behavior of weakly polydisperse sticky hard spheres: Perturbation theory for the Percus-Yevick solution
Riccardo Fantoni, Domenico Gazzillo, Achille Giacometti +1
We study the effects of size polydispersity on the gas-liquid phase behaviour of mixtures of sticky hard spheres. To achieve this, the system of coupled quadratic equations for the…
Enhancing the Violation of the Einstein-Podolsky-Rosen Local Realism by Quantum Hyper-entanglement
Marco Barbieri, Francesco De Martini, Paolo Mataloni +2
Mermin's observation [Phys. Rev. Lett. {\bf 65}, 1838 (1990)] that the magnitude of the violation of local realism, defined as the ratio between the quantum prediction and the clas…
Stable Control of Pulse Speed in Parametric Three-Wave Solitons
Antonio Degasperis, Matteo Conforti, Fabio Baronio +1
We analyze the control of the propagation speed of three wave packets interacting in a medium with quadratic nonlinearity and dispersion. We found analytical expressions for mutual…
On Equilibrium Dynamics of Spin-Glass Systems
A. Crisanti, L. Leuzzi
We present a critical analysis of the Sompolinsky theory of equilibrium dynamics. By using the spherical spin glass model we test the asymptotic static limit of the Sompolins…
Quantum phase transition in spin systems studied through entanglement estimators
Andrea Fubini, Stephan Haas, Tommaso Roscilde +2
Entanglement represents a pure quantum effect involving two or more particles. Spin systems are good candidates for studying this effect and its relation with other collective phen…
Classical and quantum q-deformed physical systems
A. Lavagno, A. M. Scarfone, P. Narayana Swamy
On the basis of the non-commutative q-calculus, we investigate a q-deformation of the classical Poisson bracket in order to formulate a generalized q-deformed dynamics in the class…
The Generalized Lyapunov Theorem and its Application to Quantum Channels
Daniel Burgarth, Vittorio Giovannetti
We give a simple and physically intuitive necessary and sufficient condition for a map acting on a compact metric space to be mixing (i.e. infinitely many applications of the map t…
Regimes of stability of accelerator modes
Rebecca Hihinashvili, Tali Oliker, Yaniv S. Avizrats +3
The phase diagram of a simple area-preserving map, which was motivated by the quantum dynamics of cold atoms, is explored analytically and numerically. Periodic orbits of a given w…
