Simple glass models and their quantum annealing.
We study first-order quantum phase transitions in mean-field spin glasses. We solve the quantum random energy model using elementary methods and show that at the transition the eigenstate suddenly projects onto the unperturbed ground state and that the gap between the lowest states is exponentially small in the system size. We argue that this is a generic feature of all "random first-order" mod...
متن کاملPlasmonic molecules via glass annealing in hydrogen
UNLABELLED Growth of self-assembled metal nanoislands on the surface of silver ion-exchanged glasses via their thermal processing in hydrogen followed by out-diffusion of neutral silver is studied. The combination of thermal poling of the ion-exchanged glass with structured electrode and silver out-diffusion was used for simple formation of separated groups of several metal nanoislands presenti...
متن کاملTheory of quantum annealing of an Ising spin glass.
Probing the lowest energy configuration of a complex system by quantum annealing was recently found to be more effective than its classical, thermal counterpart. By comparing classical and quantum Monte Carlo annealing protocols on the two-dimensional random Ising model (a prototype spin glass), we confirm the superiority of quantum annealing relative to classical annealing. We also propose a t...
متن کاملKnowledge-Based Simulation of a Glass Annealing Process: An AI Application in the Glass Industry
This paper describes a knowledge-based simulation system for a glass annealing process. The long ovens, known as lehrs, in which annealing takes place are not well understood by their operators. In fact, only a few experts can predict the effects of a change in the lehr controls. Attempts to simulate the behavior of the lehr using conventional methods have not been successful due to the size an...
