Dirac Strings and Magnetic Monopoles in Spin Ice Dy2Ti2O7
D. J. P. Morris, D. A. Tennant, S. A. Grigera +11
While sources of magnetic fields - magnetic monopoles - have so far proven elusive as elementary particles, several scenarios have been proposed recently in condensed matter physic…
Unconventional magnetization processes and thermal runaway in spin-ice DyTiO
D. Slobinsky, C. Castelnovo, R. A. Borzi +4
We investigate the non-equilibrium behavior of the spin-ice material DyTiO by studying its magnetization as a function of the rate at which an external field is swept.…
Interplay of Topological Order and Spin Glassiness in the Toric Code under Random Magnetic Fields
D. I. Tsomokos, T. J. Osborne, C. Castelnovo
We analyze the toric code model in the presence of quenched disorder, which is introduced via different types of random magnetic fields. In general, close to a quantum phase transi…
Quantum mechanical and information theoretic view on classical glass transitions
Claudio Castelnovo, Claudio Chamon, David Sherrington
Using the mapping of the Fokker-Planck description of classical stochastic dynamics onto a quantum Hamiltonian, we argue that a dynamical glass transition in the former must have a…
