The Role of dimensionality in the stability of a confined Bose gas

Luca Salasnich

We study analytically the ground-state stability of a Bose-Einstein condensate (BEC) confined in an harmonic trap with repulsive or attractive zero-range interaction by minimizing…

Quantum State Reconstruction of a Bose-Einstein Condensate

Stefano Mancini, Paolo Tombesi

We propose a tomographic scheme to reconstruct the quantum state of a Bose-Einstein condensate, exploiting the radiation field as a probe and considering the atomic internal degree…

Interference effects in f-deformed fields

Stefano Mancini, Paolo Tombesi, Vladimir I. Man'ko

We show how the introduction of an algeabric field deformation affects the interference phenomena. We also give a physical interpretation of the developed theory.

On the Convergence of the WKB Series for the Angular Momentum Operator

Luca Salasnich, Fabio Sattin

In this paper we prove a recent conjecture [Robnik M and Salasnich L 1997 J. Phys. A: Math. Gen. 30 1719] about the convergence of the WKB series for the angular momentum operator.…

SWKB for the Angular Momentum

Luca Salasnich, Fabio Sattin

In this paper we solve the eigenvalue problem of the angular momentum operator by using the supersymmetric semiclassical quantum mechanics (SWKB), and show that it gives the correc…

Macroscopic Coherence for a Trapped Electron

Stefano Mancini, Paolo Tombesi

We investigate the possibility of generating quantum macroscopic coherence phenomena by means of relativistic effects on a trapped electron.

Measuring the Cyclotron State of a Trapped Electron

Stefano Mancini, Paolo Tombesi

We propose the cyclotron state retrieval of an electron trapped in a Penning trap by using different measurement schemes based on suitable modifications of the applied electromagne…
