Mechanisms for Spin-Supersolidity in S=1/2 Spin-Dimer Antiferromagnets
J. -D. Picon, A. F. Albuquerque, K. P. Schmidt +3
Using perturbative expansions and the contractor renormalization (CORE) algorithm, we obtain effective hard-core bosonic Hamiltonians describing the low-energy physics of s…
Quantum Phase Transition in a Heisenberg Antiferromagnet on a Square Lattice with Strong Plaquette Interactions
A. Fabricio Albuquerque, Matthias Troyer, Jaan Oitmaa
We present numerical results for an Heisenberg antiferromagnet on a inhomogeneous square lattice with tunable interaction between spins belonging to different plaquettes. E…
Engineering exotic phases for topologically-protected quantum computation by emulating quantum dimer models
A. Fabricio Albuquerque, Helmut G. Katzgraber, Matthias Troyer +1
We use a nonperturbative extended contractor renormalization (ENCORE) method for engineering quantum devices for the implementation of topologically protected quantum bits describe…
