Highly Anisotropic Scaling Limits [PDF]
Journal of Statistical Physics, 2015 We consider a highly anisotropic $d=2$ Ising spin model whose precise definition can be found at the beginning of Section 2. In this model the spins on a same horizontal line (layer) interact via a $d=1$ Kac potential while the vertical interaction is between nearest neighbors, both interactions being ferromagnetic.

Nuclear Physics B, 2022 Using the saddle point method, we give an explicit form of the planar free energy and Wilson loops of unitary matrix models in the one-cut regime. The multi-critical unitary matrix models are shown to undergo third-order phase transitions at two points ...

Optimal scaling and diffusion limits for the Langevin algorithm in high dimensions [PDF]
, 2011 The Metropolis-adjusted Langevin (MALA) algorithm is a sampling algorithm which makes local moves by incorporating information about the gradient of the target density. In this paper we study the efficiency of MALA on a natural class of target measures

Earth’s Complexity Is Non-Computable: The Limits of Scaling Laws, Nonlinearity and Chaos
Entropy, 2021 Current physics commonly qualifies the Earth system as ‘complex’ because it includes numerous different processes operating over a large range of spatial scales, often modelled as exhibiting non-linear chaotic response dynamics and power scaling laws ...

LIMITS ON THE NON-COMMUTATIVITY SCALE [PDF]
CPT and Lorentz Symmetry, 2002 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

Scaling limits of dS vacua and the swampland
Journal of High Energy Physics, 2019 We discuss the properties of massive type IIA flux compactifications. In particular, we investigate in which case one can obtain dS vacua at large volume and small coupling.

Theoretical limits of scaling-down internal combustion engines [PDF]
, 2010 Small-scale energy conversion devices are being developed for a variety of applications; these include propulsion units for micro aerial vehicles (MAV). The high specific energy of hydrocarbon and hydrogen fuels, as compared to other energy storing means,

Kibble-Zurek scaling in quantum speed limits for shortcuts to adiabaticity
Physical Review Research, 2020 Geometric quantum speed limits quantify the tradeoff between the rate at which quantum states can change and the resources that are expended during the evolution. Counterdiabatic driving is a unique tool from shortcuts to adiabaticity to speed up quantum
