Kavli Affiliate: Natalia Chepiga | First 5 Authors: Bernhard Lüscher, Frédéric Mila, Natalia Chepiga, , | Summary: We investigate the nature of the phase transitions in the quantum Ashkin-Teller chain in the presence of chiral perturbations. We locate the Lifshitz line separating a region of direct chiral transitions from the region where the transition is […]
