Quantum Entropies and Decoherence for the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
I study the scaling behavior in the physical parameters of dynamical entropies, classical and quantum, in a specifically devised model of collision-induced decoherence in a chaotic…
Behavior of correlation functions in the dynamics of the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
The multi-particle Arnol'd cat is a generalization of the Hamiltonian system, both classical and quantum, whose period evolution operator is the renown map that bears its name. It…
A Scale-Dependent Distance Functional between Past Light Cones in Cosmology
Mauro Carfora, Francesca Familiari
We discuss a rigorous procedure for quantifying the difference between our past lightcone and the past lightcone of the fiducial Friedmann-Lemaitre-Robertson-Walker spacetime model…
Ricci curvature and quantum geometry
Mauro Carfora, Francesca Familiari
We describe a few elementary aspects of the circle of ideas associated with a quantum field theory (QFT) approach to Riemannian Geometry, a theme related to how Riemannian structur…
On Forms, Cohomology, and BV Laplacians in Odd Symplectic Geometry
R. Catenacci, C. A. Cremonini, P. A. Grassi +1
We study the cohomology of the complexes of differential, integral and pseudo forms on odd symplectic manifolds taking the wedge product with the symplectic form as differential. W…
Regularities in the transformation of the oscillating decay rate in moving unstable quantum systems
Filippo Giraldi
Decay laws of moving unstable quantum systems with oscillating decay rates are analyzed over intermediate times. The transformations of the decay laws at rest and of the intermedia…
-Algebra from Supermanifolds
Roberto Catenacci, Pietro Antonio Grassi, Simone Noja
Inspired by the analogy between different types of differential forms on supermanifolds and string fields in superstring theory, we construct new multilinear non-associative produc…
Generalized dimensions, large deviations and the distribution of rare events
Théophile Caby, Davide Faranda, Giorgio Mantica +2
Generalized dimensions of multifractal measures are usually seen as static objects, related to the scaling properties of suitable partition functions, or moments of measures of cel…
Wess-Zumino and Super Yang-Mills Theories in D=4 Integral Superspace
L. Castellani, R. Catenacci, P. A. Grassi
We reconstruct the action of Wess-Zumino and super-Yang-Mills theories, using integral top forms on the supermanifold . Choosing differen…
Super Quantum Mechanics in the Integral Form Formalism
L. Castellani, R. Catenacci, P. A. Grassi
We reformulate Super Quantum Mechanics in the context of integral forms. This framework allows to interpolate between different actions for the same theory, connected by different…
Neural Networks retrieving Boolean patterns in a sea of Gaussian ones
Elena Agliari, Adriano Barra, Chiara Longo +1
Restricted Boltzmann Machines are key tools in Machine Learning and are described by the energy function of bipartite spin-glasses. From a statistical mechanical perspective, they…
Regular patterns in the information flow of local dephasing channels
Filippo Giraldi
Consider local dephasing processes of a qubit that interacts with a structured reservoir of frequency modes or a thermal bath, with Ohmic-like spectral density (SD). It is known th…
Palatini formulation of non-local gravity
F. Briscese, M. L. Pucheu
We derive the dynamical equations for a non-local gravity model in the Palatini formalism and we discuss some of the properties of this model. We have shown that, in some specific…
Hodge Dualities on Supermanifolds
Leonardo Castellani, Roberto Catenacci, Pietro Antonio Grassi
We discuss the cohomology of superforms and integral forms from a new perspective based on a recently proposed Hodge dual operator. We show how the superspace constraints (a.k.a. r…
The Geometry of Supermanifolds and New Supersymmetric Actions
L. Castellani, R. Catenacci, P. A. Grassi
We construct the Hodge dual for supermanifolds by means of the Grassmannian Fourier transform of superforms. In the case of supermanifolds it is known that the superforms are not s…
Open system approach to the internal dynamics of a model multilevel molecule
Filippo Giraldi, Francesco Petruccione
A model multilevel molecule described by two sets of rotational internal energy levels of different parity and degenerate ground states, coupled by a constant interaction, is consi…
Equilibrium statistical mechanics on correlated random graphs
Adriano Barra, Elena Agliari
Biological and social networks have recently attracted enormous attention between physicists. Among several, two main aspects may be stressed: A non trivial topology of the graph d…
A Hebbian approach to complex network generation
Elena Agliari, Adriano Barra
Through a redefinition of patterns in an Hopfield-like model, we introduce and develop an approach to model discrete systems made up of many, interacting components with inner degr…
Entanglement entropy and the determination of an unknown quantum state
Gerardo Aquino, Filippo Giraldi
An initial unknown quantum state can be determined with a single measurement apparatus by letting it interact with an auxiliary, "Ancilla", system as proposed by Allahverdyan, Bali…
Stochastic Self-Similar and Fractal Universe
G. Iovane, E. Laserra, F. S. Tortoriello
The structures formation of the Universe appears as if it were a classically self-similar random process at all astrophysical scales. An agreement is demonstrated for the present h…
MEDEA: a real time imaging pipeline for pixel lensing
G. Iovane, S. Capozziello, G. Longo
Pixel lensing is a technique used to search for baryonic components of dark matter (MACHOs) and allows to detect microlensing events even when the target galaxies are not resolved…
