Pairing Instability of Bose Gas with Attractive Interaction
نویسندگان
چکیده
We study the Evans-Imry pairing phase of dilute homogeneous bose gas with attractive interaction. We find that it is generally unstable against fluctuations in pairing. Therefore in addition to the well-known mechanical collapse, the system can also collapse due to the pairing instability. Under certain conditions the critical temperature of pairing instability can be higher than that of mechanical collapse.

Pairing Instability and Mechanical Collapse of a Bose Gas with an Attractive Interaction
We study the system of a dilute homogeneous bose gas with an attractive interaction within the variational wave-function approach. We find that the pairing phase is unstable against fluctuations in pairing. The system can collapse due to this pairing instability in addition to the well-known mechanical collapse. The critical temperatures of pairing instability and mechanical collapse are higher...
متن کاملFinite Temperature Collapse of a Bose Gas with Attractive Interactions
We study the mechanical stability of the weakly interacting Bose gas with attractive interactions, and construct a unified picture of the collapse valid from the low temperature condensed regime to the high temperature classical regime. As we show, the non-condensed particles play a crucial role in determining the region of stability, even providing a mechanism for collapse in the non-condensed...
متن کاملAttractive Boson and the Gas-Liquid Condensation
We calculate a grand partition function of the attractive Bose gas in the infinite space within some approximations. Using the idea of the Yang-Lee zeros, it is proved that the gas-liquid condensation occurs before the conventional condition of the Bose-Einstein condensation is satisfied. Further, it is pointed out that Bosons with a zero momentum play a role of a trigger to this gas-liquid con...
متن کاملReply to a Comment on ”the Role of Dimensionality in the Stability of a Confined Condensed Bose Gas”
As pointed out by the authors of the comment quant-ph/9712046, in our paper quant-ph/9712030 we studied in detail the metastability of a Bose– Einstein Condensate (BEC) confined in an harmonic trap with zero–range interaction. As well known, the BEC with attractive zero–range interaction is not stable but can be metastable. In our paper we analyzed the role of dimensionality for the metastabili...
متن کاملBosons and Fermions near Feshbach resonances
Near Feshbach resonances, n|a|3 ≫ 1, systems of Bose and Fermi particles become strongly interacting/dense. In this unitary limit both bosons and fermions have very different properties than in a dilute gas, e.g., the energy per particle approach a value h̄n2/3/m times an universal many-body constant. Calculations based upon an approximate Jastrow wave function can quantitatively describe recent...
