The synergy between experiment, theory, and simulations enables a microscopic analysis of spin-glass dynamics in a magnetic field in the vicinity of and below the spin-glass transition temperature T g. The spin-glass correlation length, ξ(t, t w; T), is analysed both in experiments and in simulations in terms of the waiting time t w after the spin glass has been cooled down to a stabilised measuring temperature T < T g and of the time t after the magnetic field is changed. This correlation…

Amorphous Order and Nonlinear Susceptibilities in Glassy Materials.

- MedicineThe journal of physical chemistry. B

It is argued that an anomalous growth of the peak value of nonlinear susceptibilities is a signature of growing "amorphous order" in the system, with spin-glasses as a case in point.

Droplet-scaling versus replica symmetry breaking debate in spin glasses revisited.

The droplet-scaling picture is used to show that the apparent nonzero value of α when L<L^{*} should be 2θ, where θ is the domain wall energy scaling exponent, in reasonable agreement with the reported values of α.

Slow growth of magnetic domains helps fast evolution routes for out-of-equilibrium dynamics.

It is shown that the slow growth of magnetic domains shortens the overall time that the system takes to reach a final desired state in the two-dimensional Ising model.

Effect of Resource Dynamics on Species Packing in Diverse Ecosystems.

- Business, MedicinePhysical review letters

A generalized consumer resource model with externally supplied resources is analyzed and shows that-in contrast to self-renewing resources-species can occupy only half of all available environmental niches, which motivates a new schema for classifying ecosystems based on species packing properties.

One-step replica-symmetry-breaking phase below the de Almeida-Thouless line in low-dimensional spin glasses.

It is argued that the quasi-first-order transition could persist down to arbitrarily small nonzero fields, with a transition to full RSB still expected at lower temperature, and may explain the reported absence of a diverging correlation length in the presence of a magnetic field in low-dimensional spin glasses in some simulations and in high-temperature series expansions.

Scaling Law Describes the Spin-Glass Response in Theory, Experiments, and Simulations.

- Physics, MedicinePhysical review letters
- 2020

The correlation length ξ, a key quantity in glassy dynamics, can now be precisely measured for spin glasses both in experiments and in simulations by introducing a scaling law that takes into account both the magnetic field and the time-dependent spin-glass correlation length.
