New scenario for the emergence of non-conventional Bose-Einstein condensation. Beyond the notion of energy gap
Marco Corgini
A stable non ideal Bose system whose energy operator includes a perturbations depending on the square root of the number operator associated to the zero mode energy is analyzed, de…

Note on a Non Linear Perturbation of the Ideal Bose Gas
M. Corgini, R. Tabilo
In this work we show that the introduction of a U(1) symmetry breaking field in the energy operator of the boson-free gas, is equivalent, in the thermodynamic limit, to the inclusi…

Coexistence of Non-Conventional Condensates in Two-Level Bose Atom System
M. Corgini, C. Rojas-Molina, D. P. Sankovich
In the framework of the Bogolyubov approximation and using the Bogolyubov inequalities we give a simple proof of the coexistence of two non-conventional Bose-Einstein condensates i…
