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
the quantum damped harmonic oscillator 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...
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...
