What is the group of a quantum group? From to MPO representations of
Weronika Wiesiolek, Romain Couvreur, Dmitry Chernyak +2
Generalized symmetries realized by matrix product operators (MPOs) have so far been tied to discrete data leaving continuous symmetries outside the framework. Quantum groups fill t…
On truncations of the Chalker-Coddington model
Romain Couvreur, Eric Vernier, Jesper Lykke Jacobsen +1
The supersymmetric reformulation of physical observables in the Chalker-Coddington model (CC) for the plateau transition in the integer quantum Hall effect leads to a reformulation…
Observation of non-scalar and logarithmic correlations in 2D and 3D percolation
Xiaojun Tan, Romain Couvreur, Youjin Deng +1
Percolation, a paradigmatic geometric system in various branches of physical sciences, is known to possess logarithmic factors in its correlators. Starting from its definition, as…
Non-scalar operators for the Potts model in arbitrary dimension
Romain Couvreur, Jesper Lykke Jacobsen, Romain Vasseur
We investigate the operator content of the Q-state Potts model in arbitrary dimension, using the representation theory of the symmetric group. In particular we construct all possib…
Entanglement in non-unitary quantum critical spin chains
Romain Couvreur, Jesper Lykke Jacobsen, Hubert Saleur
Entanglement entropy has proven invaluable to our understanding of quantum criticality. It is natural to try to extend the concept to non-unitary quantum mechanics, which has seen…
Kac boundary conditions of the logarithmic minimal models
Paul A. Pearce, Elena Tartaglia, Romain Couvreur
We develop further the implementation and analysis of Kac boundary conditions in the general logarithmic minimal models with and coprime. Worki…
