Ultracold fermions with repulsive interactions
An ultracold Fermi gas with repulsive interaction has been studied. For weak interactions, the atomic gas is metastable, and the interactions were characterized by obtaining the isothermal compressibility from atomic density profiles. For stronger interactions (kFa 1), rapid conversion into Feshbach molecules is observed. When the conversion rate becomes comparable to the Fermi energy divided...
متن کاملSpinless Fermions with Repulsive Interactions
In this paper, we discuss the mean-field treatment of fermionic systems and the critical properties near the phase transitions at zero and finite temperature, respectively. Specifically, we consider the spinless fermion hopping on a square lattice, with nearest-neighbor repulsive interactions. We found that at intermediate repulsion strength there is a second-order phase transition from the Fer...
متن کاملStructure and phase behavior of a two-dimensional system with core-softened and long-range repulsive interactions.
The structure and phase behavior of a two-dimensional system with purely repulsive core-softened and long-range interactions are studied using Monte Carlo computer simulations. The pair interactions are of the form, u(r)=4epsilon[(sigma/r)(12)-(sigma/r)(6)]+epsilon(')(sigma/r)(3), with the energy parameter, epsilon(')=(8sqrt[6]/9)epsilon chosen to give a stationary point of inflection in the pa...
متن کاملDynamics of interactions involving deformable drops: hydrodynamic dimpling under attractive and repulsive electrical double layer interactions.
A model developed previously to analyze force measurements between two deformable droplets in the atomic force microscope [Langmuir 2005, 21, 2912-2922] is used to model the drainage of an aqueous film between a mica plate and a deformable mercury drop for both repulsive and attractive electrical double-layer interactions between the mica and the mercury. The predictions of the model are compar...
متن کاملHigh-temperature water–rock interactions and hydrothermal environments in the chondrite-like core of Enceladus
It has been suggested that Saturn's moon Enceladus possesses a subsurface ocean. The recent discovery of silica nanoparticles derived from Enceladus shows the presence of ongoing hydrothermal reactions in the interior. Here, we report results from detailed laboratory experiments to constrain the reaction conditions. To sustain the formation of silica nanoparticles, the composition of Enceladus'...
