NONPERTURBATIVE DOUBLE SCALING LIMITS [PDF]
Recently, the author has proposed a generalization of the matrix and vector models approach to the theory of random surfaces and polymers. The idea is to replace the simple matrix or vector (path)-integrals by gauge theory or nonlinear σ model (path)-integrals. We explain how this solves one of the most fundamental limitations of the classic approach:

A recipe for cracking the quantum scaling limit with machine learned electron densities
A long-standing goal of science is to accurately simulate large molecular systems using quantum mechanics. The poor scaling of current quantum chemistry algorithms on classical computers, however, imposes an effective limit of about a few dozen atoms on ...

Scaling of Metabolic Scaling within Physical Limits [PDF]
Both the slope and elevation of scaling relationships between log metabolic rate and log body size vary taxonomically and in relation to physiological or developmental state, ecological lifestyle and environmental conditions. Here I discuss how the recently proposed metabolic-level boundaries hypothesis (MLBH) provides a useful conceptual framework for

LIMITS ON THE NON-COMMUTATIVITY SCALE [PDF]
A non-vanishing vacuum expectation value for an antisymmetric tensor field leads to the violation of Lorentz invariance, controlled by the dimension (-2) parameter, theta_{mu nu}. We assume that the zeroth order term in theta-expansion represents the Standard Model and study the effects induced by linear terms in theta_{mu nu}. If coupling to theta_{mu

Hydrodynamic scaling limit of continuum solid-on-solid model
A fourth-order nonlinear evolution equation is derived from a microscopic model for surface diffusion, namely, the continuum solid-on-solid model.

On multiple-particle continuous-time random walks
Scaling limits of continuous-time random walks are used in physics to model anomalous diffusion in which particles spread at a different rate than the classical Brownian motion.

On the scaling limits of planar percolation [PDF]
We prove Tsirelson's conjecture that any scaling limit of the critical planar percolation is a black noise. Our theorems apply to a number of percolation models, including site percolation on the triangular grid and any subsequential scaling limit of bond percolation on the square grid.

Scaling of fracture systems in geological media [PDF]
Scaling in fracture systems has become an active field of research in the last 25 years motivated by practical applications in hazardous waste disposal, hydrocarbon reservoir management, and earthquake hazard assessment.

The D 3 2 $$ {D}_3^{(2)} $$ spin chain and its finite-size spectrum
Using the analytic Bethe ansatz, we initiate a study of the scaling limit of the quasi-periodic D 3 2 $$ {D}_3^{(2)} $$ spin chain. Supported by a detailed symmetry analysis, we determine the effective scaling dimensions of a large class of states in the
