Critical bifurcation and deconfined quantum criticality in an interacting cluster Ising chain
Sourabh, Bachana Beradze, Mikheil Tsitsishvili +2
We investigate the cluster Ising chain with an additional nearest-neighbor interaction using tensor-network methods and a weak-coupling field theory. Without the interaction, the J…
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…
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…

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…

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…
