Quantum corrections and multioccupancy in a semi-classical gas
Loris Ferrari
The quantum corrections to the behavior of a semi-classical gas can be expressed as a power series of the ratio between the cube of De Broglie's thermal wavelength and the sp…
Condensation phenomena of ions in an electrostatic logarithmic trap
Loris Ferrari
The effects of an electrostatic logarithmic trap (ELT) on an ionic gas confined in a cylindric chamber are studied in detail, with special reference to the effects of the ion-ion C…
Gas in external fields: the weird case of the logarithmic trap
Loris Ferrari
The effects of an attractive logarithmic potential on a gas of non interacting particles (Bosons or Fermions), in a box of volume , are studied in …
Boson thermodynamics in the gravity field
Loris Ferrari, Fabrizio Pavan
A uniform force like the weight has been shown to forbid Bose-Einstein condensation (BEC), due to the discreteness of the Airy spectrum, resulting from the weight. We show that BEC…
Why pushing a bell does not produce a sound
Loris Ferrari
The difference between "beating" and "pushing" results in the perception that a push just makes the object move as a whole, while a beat produces also a sound. Through a detailed a…
Quantum Parametric Resonance of a dissipative oscillator: fading and persistent memory in the long-time evolution
Loris Ferrari
The evolution of a quantum oscillator, with periodically varying frequency and damping, is studied in the two cases of parametric resonance (PR) producing a limited, or unlimited s…
Parametric Resonance in a dissipative system á la Kronig-Penney
Loris Ferrari
The competition between parametric resonance (PR) and dissipation is studied in the damped Kronig-Penney model, with time-dependent dissipation rate gamma(t). In the classical case…
Bogoliubov theory of interacting bosons: new insights from an old problem
Loris Ferrari
In a gas of interacting bosons, the Hamiltonian , obtained by dropping all the interaction terms between free bosons with moment , is diagona…
Exact diagonalization of the truncated Bogoliubov Hamiltonian
Loris Ferrari
The present short note is simply intended to communicate that I have analytically diagonalized the Bogoliubov truncated Hamiltonian ~\cite{Bogo1,Bogo2}, in an interacting boso…
Exact canonic eigenstates of the truncated Bogoliubov Hamiltonian in an interacting bosons gas
Loris Ferrari
In a gas of weakly interacting bosons \cite{Bogo1, Bogo2}, a truncated canonic Hamiltonian follows from dropping all the interaction terms between free bosons…
Boltzmann vs Gibbs: a finite-size match
Loris Ferrari
The long standing contrast between Boltzmann's and Gibbs' approach to statistical thermodynamics has been recently rekindled by Dunkel and Hilbert [1], who criticize the notion of…
Bound states and expansion dynamics of interacting bosons on a one-dimensional lattice
Cristian Degli Esposti Boschi, Elisa Ercolessi, Loris Ferrari +3
The expansion dynamics of bosonic gases in optical lattices has recently been the focus of increasing attention, both experimental and theoretical. We consider, by means of numeric…
Ab initio analysis of the x-ray absorption spectrum of the myoglobin-carbon monoxide complex: Structure and vibrations
G. Veronesi, C. Degli Esposti Boschi, L. Ferrari +4
We present a comparison between Fe K-edge x-ray absorption spectra of carbonmonoxy-myoglobin and its simulation based on density-functional theory determination of the structure an…
