Life-time and hierarchy of memory in the dissipative quantum model of brain
Eleonora Alfinito, Giuseppe Vitiello
Some recent developments of the dissipative quantum model of brain are reported. In particular, the time-dependent frequency case is considered with its implications on the differe…
Schwarzschild Field with Maximal Acceleration Corrections
A. Feoli, G. Lambiase, G. Papini +1
We consider a model in which accelerated particles experience line--elements with maximal acceleration corrections. When applied to the Schwarzschild metric, the effective field ex…
Higher-Order Corrections to the Effective Gravitational Action from Noether Symmetry Approach
S. Capozziello, G. Lambiase
Higher-order corrections of Einstein-Hilbert action of general relativity can be recovered by imposing the existence of a Noether symmetry to a class of theories of gravity where R…
Selection Rules in Minisuperspace Quantum Cosmology
S. Capozziello, G. Lambiase
The existence of a Noether symmetry for a given minisuperspace cosmological model is a sort of selection rule to recover classical behaviours in cosmic evolution since oscillatory…
Quantum dissipation and neural net dynamics
Eliano Pessa, Giuseppe Vitiello
Inspired by the dissipative quantum model of brain, we model the states of neural nets in terms of collective modes by the help of the formalism of Quantum Field Theory. We exhibit…
Low-energy behavior of the spin-tube and spin-orbital models
E. Orignac, R. Citro, N. Andrei
The low-energy effective Hamiltonian of three coupled spin chains with periodic boundary conditions (spin tube) is expressed, in the limit of strong interchain coupling, in terms o…
Casimir energy of a dilute dielectric ball in the mode summation method
G. Lambiase, G. Scarpetta, V. V. Nesterenko
In the --approximation the Casimir energy of a dilute dielectric ball is derived using a simple and clear method of the mode summation. The addition theorem for the Be…
Casimir energy of a non-uniform string
L. Hadasz, G. Lambiase, V. V. Nesterenko
The Casimir energy of a non-uniform string built up from two pieces with different speed of sound is calculated. A standard procedure of subtracting the energy of an infinite unifo…
Exact properties of the chemical potential-density relation at finite temperature in the Hubbard model
Sze-Shiang Feng, Ferdinando Mancini
We draw some rigorous conclusions about the functional properties of the relation in the Hubbard model based on symmetry considerations and unitary transformations. It is sho…
Enhancement of structural rearrangement in glassy systems under shear flow
F. Corberi, G. Gonnella, D. Suppa
We extend the analysis of the mean field schematic model recently introduced for the description of glass forming liquids to the case of a supercooled fluid subjected to a shear fl…
The Conductivity Tensor for the Hubbard Model
F. Mancini, D. Villani
A new theoretical analysis of the current-charge and charge-charge propagators is presented for the Hubbard model, using the static approximation for the Composite Operator Method.…
Quantum Field Theory of Topological Defects as Inhomogeneous Condensates
Massimo Blasone, Petr Jizba
In the framework of the Closed-Time-Path formalism, we show how topological defects may arise in Quantum Field Theory as result of a localized (inhomogeneous) condensation of parti…
Controlled quantum evolutions and transitions
N. Cufaro Petroni, S. De Martino, S. De Siena +1
We study the nonstationary solutions of Fokker-Planck equations associated to either stationary or nonstationary quantum states. In particular we discuss the stationary states of q…
Neutrino Oscillations in Brans-Dicke Theory of Gravity
S. Capozziello, G. Lambiase
Flavor oscillations of neutrinos are analyzed in the framework of Brans-Dicke theory of gravity. We find a shift of quantum mechanical phase of neutrino proportional to a…
Generalized Uncertainty Principle from Quantum Geometry
S. Capozziello, G. Lambiase, G. Scarpetta
The generalized uncertainty principle of string theory is derived in the framework of Quantum Geometry by taking into account the existence of an upper limit on the acceleration of…
Inertial Effects on Neutrino Oscillations
S. Capozziello, G. Lambiase
The inertial effects on neutrino oscillations induced by the acceleration and angular velocity of a reference frame are calculated. Such effects have been analyzed in the framework…
Single and Multi-Photon Events with Missing Energy in e+e- Collisions at \sqrt{s} = 189 GeV
L3 Collaboration
Single and multi-photon events with missing energy are analysed using data collected with the L3 detector at LEP at a centre-of-mass energy of 189 GeV, for a total of 176 pb^{-1} o…
Quantum Computation using Decoherence-Free States of the Physical Operator Algebra
Sergio De Filippo
The states of the physical algebra, namely the algebra generated by the operators involved in encoding and processing qubits, are considered instead of those of the whole system-al…
Caustics in special multiple lenses
V. Bozza
Despite its mathematical complexity, the multiple gravitational lens can be studied in detail in every situation where a perturbative approach is possible. In this paper, we examin…
Quantum Backlund transformation for the integrable DST model
V. B. Kuznetsov, M. Salerno, E. K. Sklyanin
For the integrable case of the discrete self-trapping (DST) model we construct a Backlund transformation. The dual Lax matrix and the corresponding dual Backlund transformation are…
Thermodynamic identities and particle number fluctuations in weakly interacting Bose--Einstein condensates
Fabrizio Illuminati, Patrick Navez, Martin Wilkens
We derive exact thermodynamic identities relating the average number of condensed atoms and the root-mean-square fluctuations determined in different statistical ensembles for the…
Remarks on the neutrino oscillation formula
Massimo Blasone, Giuseppe Vitiello
We show that the neutrino oscillation formula recently derived in the quantum field theory framework holds true despite the arbitrariness in the mass parameter for the flavor field…
