Topological superfluidity with repulsive alkaline-earth atoms in optical lattices
L. Isaev, A. Kaufman, G. Ortiz +1
Topological superfluids are of technological relevance since they are believed to host Majorana bound states, a powerful resource for quantum computation and memory. Here we propos…
Spin mixing and protection of ferromagnetism in a spinor dipolar condensate
S. Lepoutre, K. Kechadi, B. Naylor +7
We study spin mixing dynamics in a chromium dipolar Bose-Einstein Condensate, after tilting the atomic spins by an angle with respect to the magnetic field. Spin mixing is trig…
Spin-orbit coupled correlated metal phase in Kondo lattices: an implementation with alkaline-earth atoms
L. Isaev, J. Schachenmayer, A. M. Rey
We show that an interplay between quantum effects, strong on-site ferromagnetic exchange interaction and antiferromagnetic correlations in Kondo lattices can give rise to an exotic…
Heavy-fermion valence-bond liquids in ultracold atoms: Cooperation of Kondo effect and geometric frustration
L. Isaev, A. M. Rey
We analyze a microscopic mechanism behind coexistence of a heavy Fermi liquid and geometric frustration in Kondo lattices. We consider a geometrically frustrated periodic Anderson…
Heavy antiferromagnetic phases in Kondo lattices
L. Isaev, I. Vekhter
We propose a microscopic physical mechanism that stabilizes coexistence of the Kondo effect and antiferromagnetism in heavy-fermion systems. We consider a two-dimensional quantum K…
Frustrated magnets and quantum paramagnetic phases at finite temperature
L. Isaev, G. Ortiz
We develop a general framework, which combines exact diagonalization in small clusters with a density matrix variational principle, to study frustrated magnets at finite temperatur…
