The effect of Dzyaloshinskii-Moriya interactions on the phase diagram and magnetic excitations of SrCu2(BO3)2
Judit Romhanyi, Keisuke Totsuka, Karlo Penc
The orthogonal dimer structure in the SrCu2(BO3)2 spin-1/2 magnet provides a realization of the Shastry-Sutherland model. Using a dimer-product variational wave function, we map ou…

Dimer Smectic in Extended Quantum Dimer Model -approach from pseudo S=1 Hamiltonian-
Kouki Nakata, Keisuke Totsuka
We extend Quantum Dimer Model (QDM) introduced by Rokhsar and Kivelson in such a way that the model includes resonance processes on larger loops. The strategy is to first construct…
