Collapse of Bose component in Bose-Fermi mixture with attraction between components
S. -T. Chui, V. N. Ryzhov, E. E. Tareyeva
An effective Hamiltonian for the Bose system in the mixture of ultracold atomic clouds of bosons and fermions is obtained by integrating out the Fermi degrees of freedom. An instab…
Orientational Phase Transition in solid C_60: Bifurcation Approach
Elena Tareyeva, Tatiana Schelkacheva
A simple model for the angular dependent interaction between C_60 molecules on the face-centered cubic lattice is proposed. The bifurcations of the solutions of the nonlinear integ…
Classical many-particle distribution functions: some new applications
Elena Tareyeva, Valentin Ryzhov
We present a new purely equilibrium microscopic approach to the description of liquid-glass transition in terms of space symmetry breaking of three- and four-particle distribution…
Freezing transition in three and two dimensions by the generalized density functional theory
Elena Tareyeva, Valentin Ryzhov
A brief introduction to conventional DFT of 3D freezing is given and some recent results are reviewed. The conventional DFT, however, can not be used in the 2D case, particularly,…
