Majorana physics in a Luttinger liquid with attractive interactions
Francesco Debortoli, Nitya Cuzzuol, Luca Barbiero +1
Majorana zero modes are the hallmark of topological superconductivity. In one-dimensional systems, these zero modes are usually introduced in the context of gapped, mean-field mode…
Flux Magnetism in a Strongly Interacting Dipolar Lattice Supersolid under Tunable Gauge Fields
Michele Miotto, Pietro Lombardi, Giovanni Ferioli +4
Supersolidity and magnetism are fundamental phenomena characterizing strongly correlated matter. Here we unveil a mechanism that directly connects these two regimes and can be expe…
Geometrical frustration, power law tunneling and non-local gauge fields from scattered light
Pavel P. Popov, Joana Fraxanet, Luca Barbiero +1
Designing the amplitude and range of couplings in quantum systems is a fundamental tool for exploring a large variety of quantum mechanical effects. Here, we consider off-resonant…
Deconfined quantum critical points in fermionic systems with spin-charge separation
Niccolò Baldelli, Arianna Montorsi, Sergi Julià -Farré +3
Deconfined quantum critical points are intriguing transition points not predicted by the Landau-Ginzburg-Wilson symmetry-breaking paradigm which are usually identified by the appea…
Topology meets superconductivity in a one-dimensional model of magnetic atoms
Leonardo Bellinato Giacomelli, Thomas Bland, Louis Lafforgue +3
Strongly interacting fermions represent the key constituent of several intriguing phases of matter. However, due to the inherent complexity of these systems, important regimes are…
Correlated hopping induced topological order in an atomic mixture
Ashirbad Padhan, Luca Barbiero, Tapan Mishra
The large majority of topological phases in one dimensional many-body systems are known to inherit from the corresponding single-particle Hamiltonian. In this work, we go beyond th…
