Many-body magic via Pauli-Markov chains -- from criticality to gauge theories
Poetri Sonya Tarabunga, Emanuele Tirrito, Titas Chanda +1
We introduce a method to measure many-body magic in quantum systems based on a statistical exploration of Pauli strings via Markov chains. We demonstrate that sampling such Pauli-M…
Emergence of non-Abelian SU(2) invariance in Abelian frustrated fermionic ladders
Bachana Beradze, Mikheil Tsitsishvili, Emanuele Tirrito +3
We consider a system of interacting spinless fermions on a two-leg triangular ladder with magnetic flux per triangular plaquette. Microscopically, the system exhibits a U(1)…
Quantifying non-stabilizerness through entanglement spectrum flatness
Emanuele Tirrito, Poetri Sonya Tarabunga, Gugliemo Lami +6
Non-stabilizerness - also colloquially referred to as magic - is the a resource for advantage in quantum computing and lies in the access to non-Clifford operations. Developing a c…
Spectral properties of critical 1+1D Abelian-Higgs model
Titas Chanda, Marcello Dalmonte, Maciej Lewenstein +2
The presence of gauge symmetry in 1+1D is known to be redundant, since it does not imply the existence of dynamical gauge bosons. As a consequence, in the continuum, the Abelian-Hi…
Classification and emergence of quantum spin liquids in chiral Rydberg models
Poetri Sonya Tarabunga, Giuliano Giudici, Titas Chanda +1
We investigate the nature of quantum phases arising in chiral interacting Hamiltonians recently realized in Rydberg atom arrays. We classify all possible fermionic chiral spin liqu…
First-order photon condensation in magnetic cavities: A two-leg ladder model
Zeno Bacciconi, Gian Marcello Andolina, Titas Chanda +3
We consider a model of free fermions in a ladder geometry coupled to a nonuniform cavity mode via Peierls substitution. Since the cavity mode generates a magnetic field, no-go theo…
