Commensurate Two-Component Bosons in an Optical Lattice: Ground State Phase Diagram
Bosons optical lattice superfluid quantum systems and quantum
2014/12/20
Two sorts of bosons in an optical lattice at commensurate filling factors can form five stable superfluid and insulating ground states with rich and nontrivial phase diagram. The structure of the grou...
Supersolid Phase of Hard-Core Bosons on a Triangular Lattice
Ultra stereo core bosons triangular lattice ising spin magnetic field
2014/12/20
We study properties of the supersolid phase observed for hard-core bosons on the triangular lattice near half-integer filling factor, and the phase diagram of the system at finite temperature. We find...

Fluctuations in optical lattice boson system monte carlo simulation and natural gas
2014/12/20
We study on-site occupation number fluctuations in a system of interacting bosons in an optical lattice. The ground-state distribution is obtained analytically in the limiting cases of strong and weak...
Sign-alternating interaction mediated by strongly correlated lattice bosons
Mechanism sign - alternating boson intersite grid core the model of the ground state phase diagram
2014/12/19
We reveal a generic mechanism of generating sign-alternating intersite interactions mediated by strongly correlated lattice bosons. The ground-state phase diagram of the two-component hard-core Bose–H...
Two-fermion composite quasi-bosons and deformed oscillators
Two-fermion composite quasi-bosons deformed oscillators Quantum Physics
2011/10/9
Abstract: The concept of quasi-bosons or composite bosons (like mesons, excitons etc.) has a wide range of potential physical applications. Even composed of two pure fermions, the quasi-boson creation...
Dissipation evidence for the quantum damped harmonic oscillator via pseudo-bosons

2011/7/26
Abstract: It is known that a self-adjoint, time-independent hamiltonian can be defined for the quantum damped harmonic oscillator. We show here that the two vacua naturally associated to this operator...
Simulating quantum statistics with entangled photons: a continuous transition from bosons to fermions
quantum statistics entangled photons bosons fermions
2011/9/9
In contrast to classical physics, quantum mechanics divides particles into two classes|bosons and fermions|whose exchange statistics dictate the dynamics of systems at a fundamental level . In two dim...
Abstract: In a series of recent papers the author has introduced the notion of (regular) pseudo-bosons showing, in particular, that two number-like operators, whose spectra are ${\Bbb N}_0:={\Bbb N}\c...
Abstract: In the past years several extensions of the canonical commutation relations have been proposed by different people in different contexts and some interesting physics and mathematics have bee...
Statistically induced Phase Transitions: Turning Bosons smoothly via Anyons into Fermions
Phase Transitions Fermions
2010/10/27
Anyons { particles carrying fractional statistics that interpolate between bosons and fermions { have been conjectured to exist in low dimensional systems. In the context of the fractional quantum Hal...
Ion-trap simulation of the quantum phase transition in an exactly solvable model of spins coupled to bosons

2010/3/10
It is known that arrays of trapped ions can be used to efficiently simulate a variety of many-body quantum systems. Here, we show how it is possible to build a model representing a spin chain interact...
