Thermal Ising transition in the spin-1/2 J1-J2 Heisenberg model
Olivier Gauthé, Frédéric Mila
Using an SU(2) invariant finite-temperature tensor network algorithm, we provide strong numerical evidence in favor of an Ising transition in the collinear phase of the spin-1/2 $J…
Quantum spin liquid phases in the bilinear-biquadratic two-SU(4)-fermion Hamiltonian on the square lattice
Olivier Gauthé, Sylvain Capponi, Matthieu Mambrini +1
We consider the phase diagram of the most general SU(4)-symmetric two-site Hamiltonian for a system of two fermions per site (ie self-conjugate representation) on the squar…
SU(4) topological RVB spin liquid on the square lattice
Olivier Gauthé, Sylvain Capponi, Didier Poilblanc
We generalize the construction of the spin-1/2 SU(2) Resonating Valence Bond (RVB) state to the case of the self-conjugate -representation of SU(4). As for the case of SU(2)…
Entanglement properties of the two-dimensional SU(3) AKLT state
Olivier Gauthé, Didier Poilblanc
Two-dimensional (spin-) Affleck-Kennedy-Lieb-Tasaki (AKLT) type valence bond solids on the square lattice are known to be symmetry protected topological (SPT) gapped spin liquid…
