Behavior of Ising Spin Glasses in a Magnetic Field
Thomas Jorg, Helmut G. Katzgraber, Florent Krzakala
We study the existence of a spin-glass phase in a field using Monte Carlo simulations performed along a nontrivial path in the field--temperature plane that must cross any putative…
Spin glasses and algorithm benchmarks: A one-dimensional view
Helmut G. Katzgraber
Spin glasses are paradigmatic models that deliver concepts relevant for a variety of systems. However, rigorous analytical results are difficult to obtain for spin-glass models, in…
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…
Finite versus zero-temperature hysteretic behavior of spin glasses: Experiment and theory
Helmut G. Katzgraber, D. Herisson, M. Oesth +3
We present experimental results attempting to fingerprint nonanalyticities in the magnetization curves of spin glasses found by Katzgraber et al. [Phys. Rev. Lett. 89, 257202 (2002…
