Exact SU() symmetry resolution of bosonic Hubbard models: general boson-fermion mappings and flat-band singlet-cluster states
Loïc Herviou
We show how to perform exact diagonalization of SU()-symmetric Bose-Hubbard models separately in each irreducible representation of SU(), by exploiting the Howe duality betwe…
symmetry breaking in SU(N) Fermi-Hubbard dots at zero and finite temperature
Loïc Herviou, Elodie Campan, Pierre Nataf
We address the SU(N) Fermi-Hubbard model on a chain, with the number of degenerate orbitals, or colors, for each fermion. In the limit of both large number of colors and pa…
Numerical investigation of the structure factors of the Read-Rezayi series
Loïc Herviou, Frédéric Mila
We numerically investigate the guiding center stucture factors of several states in the Read-Rezayi family. Using exact diagonalizations on the torus and density matrix renormaliza…
Even-odd effects in the SU() Heisenberg spin chain
Loïc Herviou, Sylvain Capponi, Philippe Lecheminant
The zero-temperature phase diagram of the SU() antiferromagnetic Heisenberg spin chain is investigated by means of complementary field theory and numerical approaches…
Possible restoration of particle-hole symmetry in the 5/2 Quantized Hall State at small magnetic field
Loïc Herviou, Frédéric Mila
Motivated by the experimental observation of a quantized 5/2 thermal conductance at filling , a result incompatible with both the Pfaffian and the Antipfaffian states, we ha…
Fractional Topology in Interacting 1D Superconductors
Frederick del Pozo, Loïc Herviou, Karyn Le Hur
We investigate the topological phases of two one-dimensional (1D) interacting superconducting wires and propose topological markers directly measurable from ground state correlatio…
Bipartite Fluctuations and Topology of Dirac and Weyl Systems
Loïc Herviou, Karyn Le Hur, Christophe Mora
Bipartite fluctuations can provide interesting information about entanglement properties and correlations in many-body quantum systems. We address such fluctuations in relation wit…
Bipartite charge fluctuations in one-dimensional superconductors and insulators
Loic Herviou, Christophe Mora, Karyn Le Hur
Bipartite charge fluctuations (BCF) have been introduced to provide an experimental indication of many-body entanglement. They have proved themselves to be a very efficient and use…
Driven dissipative dynamics and topology of quantum impurity systems
Karyn Le Hur, Loïc Henriet, Loïc Herviou +6
In this review, we provide an introduction and overview to some more recent advances in real-time dynamics of quantum impurity models and their realizations in quantum devices. We…
Phase Diagram and Entanglement of two interacting topological Kitaev chains
Loïc Herviou, Christophe Mora, Karyn Le Hur
A superconducting wire described by a p-wave pairing and a Kitaev Hamiltonian exhibits Majorana fermions at its edges and is topologically protected by symmetry. We consider two Ki…
