Strong zero modes from geometric chirality in quasi-one-dimensional Mott insulators
Raul A. Santos, Benjamin Béri
Strong zero modes provide a paradigm for quantum many-body systems to encode local degrees of freedom that remain coherent far from the ground state. Example systems include $\math…
Multidimensional dark space and its underlying symmetries: towards dissipation-protected qubits
Raul A. Santos, Fernando Iemini, Alex Kamenev +1
Quantum systems are always subject to interactions with an environment, typically resulting in decoherence and distortion of quantum correlations. It has been recently shown that a…
Fractional topological insulator precursors in spin-orbit fermion ladders
Raul A. Santos, Benjamin Béri
We study precursor states of fractional topological insulators (FTIs) in interacting fermionic ladders with spin-orbit coupling. Within a microscopically motivated bosonization app…
Interplay between intrinsic and emergent topological protection on interacting helical modes
Raul A. Santos, D. B. Gutman, Sam T. Carr
The interplay between topology and interactions on the edge of a two dimensional topological insulator with time reversal symmetry is studied. We consider a simple non-interacting…
Supersymmetry in the Fractional Quantum Hall Regime
Eran Sagi, Raul A. Santos
Supersymmetry (SUSY) is a symmetry transforming bosons to fermions and vice versa. Indications of its existence have been extensively sought after in high-energy experiments. Howev…
