Stability of the symmetry-protected topological phase and Ising transitions in a disordered U(1) quantum link model on a ladder
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We revisit the U(1) quantum link model in a ladder geometry, finding, by finite-size scaling, that the critical exponent and the central charge are consistent with th…
Two-dimensional - clock model: Enhanced symmetries, emergent orders, and Landau-incompatible transitions
Vishnu Pulloor Kuttanikkad, Abhishodh Prakash, Rajesh Narayanan +1
We present a comprehensive study on the frustrated - classical -state clock model with even on a two-dimensional square lattice, revealing a rich ensemble of pha…
Chiral Gravitons on the Lattice
Hernan B. Xavier, Zeno Bacciconi, Titas Chanda +2
Chiral graviton modes are elusive excitations arising from the hidden quantum geometry of fractional quantum Hall states. It remains unclear, however, whether this picture extends…
Theory of fractional quantum Hall liquids coupled to quantum light and emergent graviton-polaritons
Zeno Bacciconi, Hernan Xavier, Iacopo Carusotto +2
Recent breakthrough experiments have demonstrated how it is now possible to explore the dynamics of quantum Hall states interacting with quantum electromagnetic cavity fields. Whil…
Gapless deconfined phase in a symmetric Hamiltonian created in a cold-atom setup
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We investigate a quasi-two-dimensional system consisting of two species of alkali atoms confined in a specific optical lattice potential [Phys. Rev. A 95, 053608 (2017)]. In the lo…
