Bose-Einstein condensation in the presence of an impurity
Paola Giacconi, Fabio Maltoni, Roberto Soldati
It is shown that Bose-Einstein condensation occurs for an ideal gas in two spatial dimensions in the presence of one impurity which is described quantum mechanically in terms of a…
Non-trivial Behaviour of the Scattering Amplitude of Contact-interacting Anyons
P. Giacconi, F. Maltoni, R. Soldati
It is shown that the scattering amplitude for contact-interacting anyons does exhibit a genuine non-perturbative sector. This means that the corresponding perturbative field theore…
On the scattering amplitude in the Aharonov-Bohm gauge field
Paola Giacconi, Fabio Maltoni, Roberto Soldati
A general expression for the scattering amplitude of nonrelativistic spinless particles in the Aharonov-Bohm gauge potential is obtained within the time independent formalism. The…
Anomaly and Thermodynamics for 2D Spinors in the Aharonov--Bohm Gauge Field
P. Giacconi, F. Maltoni, R. Soldati
The axial anomaly is computed for Euclidean Dirac fermions on the plane. The dependence upon the self-adjoint extensions of the Dirac operator is investigated and its relevance con…
