On the contrary, the genuine static nonlinear susceptibility diverges everywhere on the critical boundary with unusual violation of the universal scaling by the double logarithms at the zero-temperature critical point. Implications for experiments on quantum dipolar spin glasses are also noted. This talk was rescheduled from its original date of May 12. We establish that an often-invoked local linear analysis is inappropriate for predicting the linear stability of these patterns. Using a fully nonuniform analysis, we explore the pattern formation as a function of two control parameters, and compare with existing experimental results.
Oscillations are ubiquitous in neural systems and have been the focus of several recent studies.
We propose a simple model of this partial synchronization phenomenon which allows to determine its main characteristics. Ultrathin films of metals quench condensed onto cold substrates have been employed in numerous investigations of fundamental problems in two dimensional electron physics. These include the phenomena of weak localization, the superconductor to insulator transition, and disorder induced electron correlation effects. Despite their importance, very little is known about their structure or how their structure forms. Technological challenges have impeded direct measurements of quench condensed film morphology.
