Effect of the Triplet State on the Random Telegraph Signal in Si n-MOSFETs
Enrico Prati, Marco Fanciulli, Giorgio Ferrari +1
We report on the static magnetic field dependence of the random telegraph signal (RTS) in a submicrometer silicon n-metal-oxide-semiconductor field-effect transistor. Using intense…
Physics of Solid and Liquid Alkali Halide Surfaces Near the Melting Point
T. Zykova-Timan, D. Ceresoli, U. Tartaglino +1
This paper presents a broad theoretical and simulation study of the high temperature behavior of crystalline alkali halide surfaces typified by NaCl(100), of the liquid NaCl surfac…
Optical properties of small polarons from dynamical mean-field theory
S. Fratini, S. Ciuchi
The optical properties of polarons are studied in the framework of the Holstein model by applying the dynamical mean-field theory. This approach allows to enlighten important quant…
Effects of neutron irradiation on polycrystalline Mg11B2
C. Tarantini, H. U. Aebersold, V. Braccini +13
We studied the influence of the disorder introduced in polycrystalline MgB2 samples by neutron irradiation. To circumvent self shielding effects due to the strong interaction betwe…
Finite-Temperature Renormalization Group Analysis of Interaction Effects in 2D Lattices of Bose-Einstein Condensates
A. Smerzi, P. Sodano, A. Trombettoni
By using a renormalization group analysis, we study the effect of interparticle interactions on the critical temperature at which the Berezinskii-Kosterlitz-Thouless (BKT) transiti…
Seeing zeros of random polynomials: quantized vortices in the ideal Bose gas
Yvan Castin, Zoran Hadzibabic, Sabine Stock +2
We propose a physical system allowing one to experimentally observe the distribution of the complex zeros of a random polynomial. We consider a degenerate, rotating, quasi-ideal at…
Critical and tricritical singularities of the three-dimensional random-bond Potts model for large
M. T. Mercaldo, J-Ch. Anglès d'Auriac, F. Iglói
We study the effect of varying strength, , of bond randomness on the phase transition of the three-dimensional Potts model for large . The cooperative behavior of the system…
Phase Sensitivity of a Mach-Zehnder Interferometer
Luca Pezze', Augusto Smerzi
The best performance of a Mach-Zehnder interferometer is achieved with the input state |N_T/2 + 1>|N_T/2-1 > + |N_T/2 - 1>|N_T/2+1>, being N_T the total number of atoms/photons. Th…
Electron spin echo relaxation and envelope modulation of phosphorus shallow donors in silicon
A. Ferretti, M. Fanciulli, A. Ponti +1
Spins of single donor atoms are attractive candidates for large scale quantum information processing in silicon, since quantum computation can be realized through the manipulation…
Legendre structure of the thermostatistics theory based on the Sharma-Taneja-Mittal entropy
A. M. Scarfone
The statistical proprieties of complex systems can differ deeply for those of classical systems governed by Boltzmann-Gibbs entropy. In particular, the probability distribution fun…
Critical behaviour of thin films with quenched impurities
L. Craco, L. De Cesare, I. Rabuffo +2
The critical behaviour of thin films containing quenched random impurities and inhomogeneities is investigated by the renormalization-group method. The finite-size crossover in imp…
Two generalizations of the Boltzmann equation
T. S. Biro, G. Kaniadakis
We connect two different generalizations of Boltzmann's kinetic theory by requiring the same stationary solution. Non-extensive statistics can be produced by either using correspon…
Unusual polymerization in the Li4C60 fulleride
M. Ricco, T. Shiroka, M. Belli +6
Li4C60, one of the best representatives of lithium intercalated fullerides, features a novel type of 2D polymerization. Extensive investigations, including laboratory x-ray and syn…

A. Lavagno, A. M. Scarfone, P. Narayana Swamy
On the basis of the quantum q-oscillator algebra in the framework of quantum groups and non-commutative q-differential calculus, we investigate a possible q-deformation of the clas…
Canonical partition function for anomalous systems described by the -entropy
A. M. Scarfone, T. Wada
Starting from the -distribution function, obtained by applying the maximal entropy principle to the -entropy [G. Kaniadakis, Phys. Rev. E 66 (2002), 056125], we derive the ex…
Quantum-transport theory for semiconductor nanostructures: A density-matrix formulation
Rita Claudia Iotti, Emanuele Ciancio, Fausto Rossi
A general density-matrix formulation of quantum-transport phenomena in semiconductor nanostructures is presented. More specifically, contrary to the conventional single-particle co…

Francesco De Martini, Fabio Sciarrino, Veronica Secondi
We report the realization of an entangled quantum superposition of M=12 photons by a high gain, quantum-injected optical parametric amplification. The system is found so highly res…
Excitons in boron nitride nanotubes: dimensionality effects
Ludger Wirtz, Andrea Marini, Angel Rubio
We show that the optical absorption spectra of boron nitride (BN) nanotubes are dominated by strongly bound excitons. Our first-principles calculations indicate that the binding en…
