Exact plaquette singlet phases in an orthogonal-plaquette model
C. Boos, K. P. Schmidt
We introduce a quantum spin-1/2 model hosting two exact plaquette singlet ground states in extended parameter regimes. There is an exact phase transition between both phases, at wh…

Time-reversal symmetry breaking Abelian chiral spin liquid in Mott phases of three-component fermions on the triangular lattice
C. Boos, C. J. Ganahl, M. Lajkó +5
We provide numerical evidence in favor of spontaneous chiral symmetry breaking and the concomitant appearance of an Abelian chiral spin liquid for three-component fermions on the t…

Competition between intermediate plaquette phases in SrCu(BO) under pressure
C. Boos, S. P. G. Crone, I. A. Niesen +3
Building on the growing evidence based on NMR, magnetization, neutron scattering, ESR, and specific heat that, under pressure, SrCu(BO) has an intermediate phase betwee…
