Effective de Sitter-Schwarzschild Metrics
Moorad Alexanian
An earlier work that replaced the de Sitter-Schwarzschild metric for a cosmological constant Lambda <=0 by an effective anti-de Sitter black hole analytic at Lambda = 0 is here ext…
Parametrized Version of the Generalized Aubry-André Model
Moorad Alexanian
A recently introduced recurrence-relation ansatz applied to the Bose-Hubbard model is here used in the generalized Aubry-Andre model. The resulting modified Aubry-Andre model allow…
Symmetric and Asymmetric Quantum Rabi Model
Moorad Alexanian
We introduce a modified Jaynes-Cummings model with single-photon cavity radiation field but with the atomic system instead of exchanging a single photon as in the Jaynes-Cummings m…
Ansatz for the Two-Dimensional Ising Model in an External Magnetic Field
Moorad Alexanian
An ansatz applied to the two-dimensional Ising model in an external magnetic field h gives rise to an exactly soluble model. The singularity in the magnetization found by Onsager d…
A Soluble Modified Fermi-Hubbard Model
Moorad Alexanian
A recently introduced recurrence-relation ansatz applied to the Bose-Hubbard model is here used in the Fermi-Hubbard model. The resulting modified Fermi-Hubbard model is soluble an…
Thermodynamics of a Modified Fermi-Hubbard Model
Moorad Alexanian
A recently introduced recurrence-relation ansatz applied to the Fermi-Hubbard model gives rise to a soluble model and here is used to calculate several thermodynamic observables. T…
Quantum Phase Transition in a Modified Jaynes-Cummings Model
Moorad Alexanian
We introduce a modified Jaynes-Cummings model with single-photon cavity radiation field but with the atomic system instead of exchanging a single photon as in the Jaynes-Cummings m…
Nonlocal Potentials and Crystalline Order in One and Two Dimensions
Moorad Alexanian
We revisit the seminal 1968 proof of the absence of crystalline order in two dimensions and analyze the importance played in the quantum theorem by the assumption of local pair pot…
Nearest-Neighbor Tunneling Ansatz in the Bose-Hubbard Mode
Moorad Alexanian
A recently introduced recurrence-relation ansatz applied to the Jaynes-Cummings-Hubbard model is here applied to the Bose-Hubbard model that reduced the model to an easily soluble…
Particle-Hole Ansatz in the Jaynes-Cummings-Hubbard Model
Moorad Alexanian
A recurrence relation ansatz between annihilation operators applied to the hopping interaction term of the Jaynes-Cummings-Hubbard model (JCHM) reduces the JCHM to that of the ordi…
One-dimensional Dynamics for a Discontinuous Singular Map and the Routes to Chaos
Moorad Alexanian
We visit a previously proposed discontinuous, two-parameter generalization of the continuous, one-parameter logistic map and present exhaustive numerical studies of the behavior fo…
The Dynamics of a Modified Jaynes-Cummings Model
Moorad Alexanian
We introduce a dynamical system that instead of exchanging a single photon as in the atomic system of the usual Jaynes-Cummings model (JCM), it exchanges instead a squeezed coheren…
Collapse and revival of -photon coherent states and -photon squeezed coherent states
Moorad Alexanian
We introduce the set of -photon coherent states and the set of -photon squeezed coherent states and study their collapse and revival and compare their behavior with the colla…
Angular distributions and polarization correlations of the two-photon spherical states
Moorad Alexanian, Vanik E. Mkrtchian
We have analyzed in detail the angular polarization properties in the center of mass reference frame of Landau's two-photon spherical states in momentum space. The angular distribu…
Bose-Einstein Condensation and quasicrystals
Moorad Alexanian, Vanik E. Mkrtchian
We consider interacting Bose particles in an external local potential. It is shown that large class of external quasicrystal potentials cannot sustain any type of Bose-Einstein con…
Conflicts Between Science and Religion: Epistemology to the Rescue
Moorad Alexanian
Both Albert Einstein and Erwin Schrödinger have defined what science is. Einstein includes not only physics, but also all natural sciences dealing with both organic and inorganic p…
Characteristic function and quasi-probability distribution of photons and of squeezed coherent photons
Moorad Alexanian
We consider the p-ordered characteristic function and its Fourier transform, the quasidistribution function, of squeezed coherent photons in a thermal state of photons and calculat…
Bose-Einstein Condensation and Supersolids
Moorad Alexanian, Vanik E. Mkrtchian
We consider interacting Bose particles in an external potential. It is shown that a Bose-Einstein condensate is possible at finite temperatures that describes a supersolid in three…
Mean Number and Number Variance of Squeezed Coherent Photons In a Thermal State of Photons
Moorad Alexanian
We consider the equilibrium thermal state of photons and determine the mean number and number variance of squeezed coherent photons. We use an integral representation for electro-m…
Quantum Rabi oscillations in coherent and squeezed coherent states via one- and two-photon transitions
Moorad Alexanian
We determine the Rabi oscillations for coherent and squeezed coherent states via one- and two-photon atomic transitions in two- and three-level atoms, respectively. The effect of s…
Statistical Entropy of a Schwarzschild-anti-de Sitter Black Hole
Moorad Alexanian
We calculate the intrinsic entropy of a Schwarzschild black hole in an asymptotically antide Sitter space. The statistical calculation of the entropy is based on a model for partic…
Integral representation of the cosmic microwave background spectrum
Moorad Alexanian
We use an integral representation for nonthermal radiation, which is bounded from below and above, to describe the spectrum of the cosmic microwave background (CMB). The upper boun…
Anti-Diffusion in Continuous Opinion Dynamics
Moorad Alexanian, Dylan McNamara
Considerable effort using techniques developed in statistical physics has been aimed at numerical simulations of agent-based opinion models and analysis of their results. Such work…
Quantum entropy and polarization measurements of the two-photon system
Moorad Alexanian, Vanik E. Mkrtchian
We consider the bipartite state of a two-photon polarization system and obtain the exact analytical expression for the von Neumann entropy in the particular case of a 5-parameter p…
