Oscillating Quantum Droplets from the free expansion of Logarithmic One-Dimensional Bose Gases
Omar Abel Rodríguez-López, Elías Castellanos
We analyze some issues related to the stability and free expansion of a one-dimensional logarithmic Bose-Einstein condensate, particularly its eventual relation to the formation of…
Superfluids in Polymer Quantum Mechanics
Jasel Berra-Montiel, Elías Castellanos, Alberto Molgado +1
In this work, we analyze the corrections obtained on a homogeneous one-dimensional Bose gas within the high densities limit by means of the polymer quantization scheme. Thus, start…
Dark energy as generalised superfluid excitations
Elías Castellanos, Celia Escamilla-Rivera
In this paper we present a generic form of the cosmological Equation of State derived from the formalism of Statistical Mechanics, assuming that a cosmic acceleration scenario can…
Is a Bose-Einstein Condensate a good candidate for Dark Matter? A test with Galaxy Rotation Curves
Elías Castellanos, Celia Escamilla-Rivera, Jorge Mastache
We analyze the rotation curves that correspond to a Bose--Einstein Condensate (BEC) type halo surrounding a Schwarzschild--type black hole to confront predictions of the model upon…
Bose gas to Bose-Einstein Condensate by the Phase Transition of the Klein-Gordon equation
Tonatiuh Matos, Elías Castellanos
We rewrite the complex Klein-Gordon (KG) equation with a mexican-hat scalar field potential in a thermal bath with one loop contribution as a new Gross-Pitaevskii (GP)-like equatio…
