Critical number of atoms for attractive Bose-Einstein condensates with cylindrically symmetrical traps
A. Gammal, T. Frederico, Lauro Tomio
We calculated, within the Gross-Pitaevskii formalism, the critical number of atoms for Bose-Einstein condensates with two-body attractive interactions in cylindrical traps with dif…
Lower bound to the mass of a relativistic three-boson system in the light-cone
J. P. B. C. de Melo, A. E. A. Amorim, Lauro Tomio +1
The lower bound masses of the ground-state relativistic three-boson system in 1+1, 2+1 and 3+1 space-time dimensions are obtained. We have considered a reduction of the ladder Beth…
Stability of trapped Bose-Einstein condensates
F. Kh. Abdullaev, A. Gammal, Lauro Tomio +1
In three-dimensional trapped Bose-Einstein condensate (BEC), described by the time-dependent Gross-Pitaevskii-Ginzburg equation, we study the effect of initial conditions on stabil…
Fixed-Point Hamiltonians in Quantum Mechanics
T. Frederico, A. Delfino, Lauro Tomio +1
We show how to derive fixed-point Hamiltonians in quantum mechanics from a proposed renormalization group invariance approach that relies in a subtraction procedure at a given ener…
