Oscillations toward the singularity of LRS Bianchi type IX cosmological models with Vlasov matter
Oscillations singularity of LRS Bianchi type IX cosmological models Vlasov matter
2010/12/20
We analyze the dynamics of a class of cosmological solutions of the Einstein-Vlasov equa-
tions. These equations describe an ensemble of collisionless particles (which represent galaxies or clusters ...
Breakup reaction models for two- and three-cluster projectiles
Breakup reaction models for two- three-cluster projectiles
2011/1/7
Breakup reactions are one of the main tools for the study of exotic nuclei,and in particular of their continuum. In order to get valuable information from measurements.
Unified Dark Matter scalar field models with fast transition
Unified Dark Matter scalar field fast transition
2010/12/22
We investigate the general properties of Unified Dark Matter (UDM) scalar
field models with Lagrangians with a non-canonical kinetic term, looking specifically for
models that can produce a fast tra...
Finite Quantum Models: Constructive Approach to Description of Quantum Behavior
Finite Quantum Models Constructive Approach Description Quantum Behavior
2010/11/11
Universality of quantum mechanics -- its applicability to physical systems of quite different nature and scales -- indicates that quantum behavior can be a manifestation of general mathematical proper...
The U(1) Lattice Gauge Theory Universally Connects All Classical Models with Continuous Variables, Including Background Gravity
Lattice gauge theory Statistical mechanics Quantum information
2010/11/4
We show that the partition function of many classical models with continuous degrees of freedom, e.g. abelian lattice gauge theories and statistical mechanical models, can be written as the partition...
Derivation of reduced two-dimensional fluid models via Dirac's theory of constrained Hamiltonian systems
two-dimensional fluid models Dirac's theory Hamiltonian systems
2010/4/1
We present a Hamiltonian derivation of a class of reduced plasma two-dimensional fluid models, an example being the Charney-Hasegawa-Mima equation. These models are obtained from the same parent Hamil...
Exact results for the criticality of quench dynamics in quantum Ising models
Exact results criticality of quench dynamics quantum Ising models
2010/4/12
Based on the obtained exact results we systematically study the quench dynamics of a one-dimensional spin-1/2 transverse field Ising model with zero- and finite-temperature initial states. We focus on...
Quantum models of classical mechanics: maximum entropy packets
Quantum classical mechanics maximum entropy packets
2010/4/7
In a previous paper, a project of constructing quantum models of classical properties has been started. The present paper concludes the project by turning to classical mechanics. The quantum states th...
Comment on "Dynamical reduction models" by A. Bassi and G.C. Ghirardi (arXiv:quant-ph/0302164)
Comment Dynamical reduction models A. Bassi and G.C. Ghirardi
2010/4/9
Bassi and Ghirardi have developed a new theory to address the measurement problem based upon non-linear and stochastic modifications of the Schroedinger equation, which has been given the name Quantum...
We demonstrate how to build a simulation of two dimensional physical theories describing topologically ordered systems whose excitations are in one to one correspondence with irreducible representatio...
Continuum states in generalized Swanson models
Swanson-type pseudo Hermitian Hamiltonian continuum states damped waves progressivewaves Poschl-Teller potential Morse potential
2010/4/7
A one-to-one correspondence is known to exist between the spectra of the discrete states of the non Hermitian Swanson-type Hamiltonian $ H = {\cal{A}}^{\dagger} {\cal{A}} + \alpha {\cal{A}} ^2 + \beta...

Superluminal Hidden Communication as the Underlying Mechanism for Quantum Correlations: Constraining Models
Superluminal Hidden Communication the Underlying Mechanism Quantum Correlations
2010/10/13
Since Bell’s theorem, it is known that quantum correlations cannot be described by local variables (LV) alone: if one does not want to abandon classical mechanisms for correlations, a superluminal for...
Quantum network architecture of tight-binding models with substitution sequences
Quantum network architecture of tight-binding models substitution sequences
2010/10/15
We study a two-spin quantum Turing architecture, in which discrete local rotations { m} of the Turing head spin alternate with quantum controlled NOT-operations.Substitution sequences are known to und...
