Collective modes in a quantum solid
Snir Gazit, Daniel Podolsky, Heloise Nonne +2
We provide a theoretical explanation for the optical modes observed in inelastic neutron scattering (INS) on the bcc solid phase of helium 4 [T. Markovich, E. Polturak, J. Bossy, a…
Competing Valence Bond States of Spin-3/2 Fermions on a Strongly Coupled Ladder
Edina Szirmai, Heloise Nonne
We study the possible ground state configurations of two strongly coupled chains of charge neutral spin-3/2 fermionic atoms interacting via short range van der Waals interaction. T…
Symmetry-protected topological phases of alkaline-earth cold fermionic atoms in one dimension
H. Nonne, M. Moliner, S. Capponi +2
We investigate the existence of symmetry-protected topological phases in one-dimensional alkaline-earth cold fermionic atoms with general half-integer nuclear spin I at half fillin…
Quantum criticality in the SO(5) bilinear-biquadratic Heisenberg chain
F. Alet, S. Capponi, H. Nonne +2
The zero-temperature properties of the SO(5) bilinear-biquadratic Heisenberg spin chain are investigated by means of a low-energy approach and large scale numerical calculations. I…
Competing orders in the generalized Hund chain model at half-filling
H. Nonne, E. Boulat, S. Capponi +1
By using a combination of several non-perturbative techniques -- a one-dimensional field theoretical approach together with numerical simulations using density matrix renormalizati…
Haldane charge conjecture in one-dimensional multicomponent fermionic cold atoms
H. Nonne, P. Lecheminant, S. Capponi +2
A Haldane conjecture is revealed for spin-singlet charge modes in 2N-component fermionic cold atoms loaded into a one-dimensional optical lattice. By means of a low-energy approach…
