Phase transitions in low dimensional systems via spontaneous symmetry breaking and topology
Toniolo, Daniele (Doctoral thesis at NTNU;2015:271, Doctoral thesis, 2015)In nature there exists a fundamental distinction among particles regarding their statistics. Let us consider an isolated systems of two particles: two bosons are allowed to stay in the same physical state while two fermions ... -
Superfluidity breakdown and multiple roton gaps in spin-orbit-coupled Bose-Einstein condensates in an optical lattice
Toniolo, Daniele; Linder, Jacob (Journal article, 2014)We investigate the superfluid phases of a Rashba spin-orbit-coupled Bose-Einstein condensate residing on a two-dimensional square optical lattice in the presence of an effective Zeeman field Ω. At a critical value Ω=Ωc, ...
