Tunable quantum criticality in multicomponent Rydberg arrays
Natalia Chepiga
Arrays of Rydberg atoms have appeared as a remarkably rich playground to study quantum phase transitions in one dimension. One of the biggest puzzles that was brought forward in th…
Critical properties of the quantum Ashkin-Teller chain with chiral perturbations
Bernhard Lüscher, Frédéric Mila, Natalia Chepiga
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 di…
Resilient infinite randomness criticality for a disordered chain of interacting Majorana fermions
Natalia Chepiga, Nicolas Laflorencie
The quantum critical properties of interacting fermions in the presence of disorder are still not fully understood. While it is well known that for Dirac fermions, interactions are…
Emergent U(1) symmetry in non-particle-conserving one-dimensional models
Zakaria Jouini, Natalia Chepiga, Loic Herviou +1
The properties of stable Luttinger liquid phases in models with a non-conserved number of particles are investigated. We study the Luttinger liquid phases in one-dimensional models…
Critical properties of the Majorana chain with competing interactions
Natalia Chepiga
We study critical properties of a Majorana chain in the presence of two competing interactions of the shortest possible range. The obtained phase diagram is very rich and contains…
