Ultrametric probe of the spin-glass state in a field

Helmut G. Katzgraber, Thomas Jorg, Florent Krzakala +1

We study the ultrametric structure of phase space of one-dimensional Ising spin glasses with random power-law interaction in an external random field. Although in zero field the mo…

The nature of the different zero-temperature phases in discrete two-dimensional spin glasses: Entropy, universality, chaos and cascades in the renormalization group flow

Thomas Jorg, Florent Krzakala

The properties of discrete two-dimensional spin glasses depend strongly on the way the zero-temperature limit is taken. We discuss this phenomenon in the context of the Migdal-Kada…

Energy gaps in quantum first-order mean-field-like transitions: The problems that quantum annealing cannot solve

T. Jorg, F. Krzakala, J. Kurchan +2

We study first-order quantum phase transitions in models where the mean-field traitment is exact, and the exponentially fast closure of the energy gap with the system size at the t…

First-order transitions and the performance of quantum algorithms in random optimization problems

T. Jorg, F. Krzakala, G. Semerjian +1

We present a study of the phase diagram of a random optimization problem in presence of quantum fluctuations. Our main result is the characterization of the nature of the phase tra…

Quantum Annealing of Hard Problems

Thomas Jorg, Florent Krzakala, Jorge Kurchan +1

Quantum annealing is analogous to simulated annealing with a tunneling mechanism substituting for thermal activation. Its performance has been tested in numerical simulation with m…

Overlap Interfaces in Hierarchical Spin-Glass models

Silvio Franz, T Jorg, Giorgio Parisi

We discuss interfaces in spin glasses. We present new theoretical results and a numerical method to characterize overlap interfaces and the stability of the spin-glass phase in ext…
