Nematostriction in frustrated two-dimensional Heisenberg models
Olav F. Syljuåsen, Jens Paaske
We investigate the nematic phase transition in the Heisenberg --model on square and triangular lattices, accounting for finite lattice compressibility and bond-length-dep…

Dynamical instability in a Floquet-Driven Dissipative System
Takuya Okugawa, Jens Paaske, Martin Eckstein +3
We analyse the magnon spectrum and distribution function of the antiferromagnetic phase of the Floquet-driven Hubbard model. Above a critical drive strength, we find a dynamical in…
