Dynamical properties of the random Heisenberg chain
Yu-Rong Shu, Maxime Dupont, Dao-Xin Yao +2
We use numerical techniques to study dynamical properties at finite temperature () of the Heisenberg spin chain with random exchange couplings, which realizes the random singlet…
"Haldane" phases with ultracold fermionic atoms in double-well optical lattices
P. Fromholz, S. Capponi, P. Lecheminant +2
We propose to realize one-dimensional topological phases protected by SU() symmetry using alkali or alkaline-earth atoms loaded into a bichromatic optical lattice. We derive a r…
Nearly deconfined spinon excitations in the square-lattice spin-1/2 Heisenberg antiferromagnet
Hui Shao, Yan Qi Qin, Sylvain Capponi +3
We study the dynamic spin structure factor of the spin- square-lattice Heisenberg antiferromagnet and of the - model (with 4-spin interactions and Heisenberg exchang…
Competing Bose-Glass physics with disorder-induced Bose-Einstein condensation in the doped antiferromagnet Ni(ClBr)-4SC(NH) at high magnetic fields
Maxime Dupont, Sylvain Capponi, Mladen Horvatić +1
We study the interplay between disorder and interactions for emergent bosonic degrees of freedom induced by an external magnetic field in the Br-doped spin-gapped antiferromagnetic…
Weak Versus Strong Disorder Superfluid-Bose Glass Transition in One Dimension
Elmer V. H. Doggen, Gabriel Lemarié, Sylvain Capponi +1
Using large-scale simulations based on matrix product state and quantum Monte Carlo techniques, we study the superfluid to Bose glass-transition for one-dimensional attractive hard…
