Effective interactions in a quantum Bose-Bose mixture
O. I. Utesov, M. I. Baglay, S. V. Andreev
We generalize the Beliaev diagrammatic theory of an interacting spinless Bose-Einstein condensate to the case of a binary mixture. We derive a set of coupled Dyson equations and fi…

Cascades of phase transitions in spiral magnets caused by dipolar forces
O. I. Utesov, A. V. Syromyatnikov
We present a mean-field theory describing the influence of long-range dipolar forces on the temperature transition from the paramagnetic to ordered phases in frustrated Heisenberg…
