Dyon condensation in topological Mott insulators
We consider quantum phase transitions out of topological Mott insulators in which the ground state of the fractionalized excitations (fermionic spinons) is topologically non-trivial. The spinons in topological Mott insulators are coupled to an emergent compact U (1) gauge field with a so-called ‘axion’ term. We study the confinement transitions from the topological Mott insulator to broken symm...

متن کاملEffective field theory approach to Bose–Einstein condensation
We consider the low-energy collective excitations at finite temperature of Bose– Einstein condensed gases (and liquids as well). A most general model-independent effective Lagrangian is written down according to a prescription obtained from the breakdown of the global symmetry U(1). To show how the theory predicts easily, we derive the momentum and temperature dependence of the damping of excit...
