Correlation amplitude and entanglement entropy in random spin chains
J. A. Hoyos, André P. Vieira, Nicolas Laflorencie +1
Using strong-disorder renormalization group, numerical exact diagonalization, and quantum Monte Carlo methods, we revisit the random antiferromagnetic XXZ spin-1/2 chain focusing o…
Dissipation effects in percolating quantum Ising magnets
J. A. Hoyos, Thomas Vojta
We study the effects of dissipation on a randomly dilute transverse-field Ising magnet at and close to the percolation threshold. For weak transverse fields, a novel percolation qu…
Ordered droplets in quantum magnets with long-range interactions
Thomas Vojta, Jose A Hoyos
A defect coupling to the square of the order parameter in a nearly quantum-critical magnet can nucleate an ordered droplet while the bulk system is in the paramagnetic phase. We st…
Random Antiferromagnetic SU(N) Spin Chains
J. A. Hoyos, E. Miranda
We analyze random isotropic antiferromagnetic SU(N) spin chains using the real space renormalization group. We find that they are governed at low energies by a universal infinite r…
Phase diagrams and universality classes of random antiferromagnetic spin ladders
J. A. Hoyos, E. Miranda
The random antiferromagnetic two-leg and zigzag spin-1/2 ladders are investigated using the real space renormalization group scheme and their complete phase diagrams are determined…
