The mixed spherical models were recently found to violate long-held assumptions about mean-field glassy dynamics. In particular, the threshold energy, where most stationary points are marginal and that in the simpler pure models attracts long-time dy

We study the saddle points of the p-spin model—the best understood example of a “complex” (rugged) landscape—when its N variables are complex. These points are the solutions to a system of N random equations of degree p−1. We solve for N[ov

We show that the predicted probability distributions for any N-parameter statistical model taking the form of an exponential family can be explicitly and analytically embedded isometrically in a N+N-dimensional Minkowski space. That is, the model pre

In this paper we follow up the study of ‘complex complex landscapes’ (Kent-Dobias and Kurchan 2021 Phys. Rev. Res. 3 023064), rugged landscapes of many complex variables. Unlike real landscapes, the classification of saddles by index is trivial.

We develop a phenomenological mean-field theory describing the hidden-order phase in $\mathrm{U}{\mathrm{Ru}}_{2}{\mathrm{Si}}_{2}$ as a nematic of the ${B}_{1g}$ representation staggered along the $c$ axis. Several experimental features are reproduc

We show that the predicted probability distributions for any $N$-parameter statistical model taking the form of an exponential family can be explicitly and analytically embedded isometrically in a $N{+}N$-dimensional Minkowski space. That is, the mod

We introduce a new toy model for the study of glasses: the hard-matrix model (HMM). This may be viewed as a single particle moving on $\mathrm{SO}(N)$, where there is a potential proportional to the 1-norm of the matrix. The ground states of the mode

We introduce a natural way to extend celebrated spin-cluster Monte Carlo algorithms for fast thermal lattice simulations at criticality, like Wolff, to systems in arbitrary fields, be they linear magnetic vector fields or nonlinear anisotropic ones.

The results of the renormalization group are commonly advertised as the existence of power law singularities near critical points. The classic predictions are often violated and logarithmic and exponential corrections are treated on a case-by-case ba
