The finite-temperature chiral transition in QCD with adjoint fermions
, 2004 We study the nature of the finite-temperature chiral transition in QCD with N_f light quarks in the adjoint representation (aQCD). Renormalization-group arguments show that the transition can be continuous if a stable fixed point exists in the ...

Landau levels in quasicrystals
, 2018 Two-dimensional tight-binding models for quasicrystals made of plaquettes with commensurate areas are considered. Their energy spectrum is computed as a function of an applied perpendicular magnetic field.

Krylov subspace approximations for the exponential Euler method: error estimates and the harmonic Ritz approximant [PDF]
, 2011 We study Krylov subspace methods for approximating the matrix-function vector product φ(tA)b where φ(z) = [exp(z) - 1]/z. This product arises in the numerical integration of large stiff systems of differential equations by the Exponential Euler Method ...

An acoustic study on monophthongs in Central Australian Aboriginal English
World Englishes, EarlyView.Abstract We present an acoustic analysis of monophthongal vowel production in Central Australian Aboriginal English (CAAE), providing one of the first systematic examinations of this variety spoken by English‐as‐a‐first‐language (L1) speakers in Mparntwe/Alice Springs, Australia.

Dimer models and conformal structures
Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

Quadrature-Based Vector Fitting: Implications For H2 System Approximation
, 2014 Vector Fitting is a popular method of constructing rational approximants designed to fit given frequency response measurements. The original method, which we refer to as VF, is based on a least-squares fit to the measurements by a rational function ...

The intersection of two halfspaces has high threshold degree [PDF]
, 2009 The threshold degree of a Boolean function f:{0,1}^n->{-1,+1} is the least degree of a real polynomial p such that f(x)=sgn p(x). We construct two halfspaces on {0,1}^n whose intersection has threshold degree Theta(sqrt n), an exponential improvement on ...

Predictability Affects Spoken Phonological Systems Indirectly
Language and Linguistics Compass, Volume 20, Issue 1, January/February 2026.ABSTRACT The last three decades have seen a large increase in attempts to explain phonetic and phonological patterns using information theoretic properties such as frequency and predictability. One recurring theme is the attempt to explain phonetic and phonological weakening as following directly from low information content. I argue that the actuation

Computing with functions in spherical and polar geometries II. The disk
, 2017 A collection of algorithms is described for numerically computing with smooth functions defined on the unit disk. Low rank approximations to functions in polar geometries are formed by synthesizing the disk analogue of the double Fourier sphere method ...

Computational Modeling of Reticular Materials: The Past, the Present, and the Future
Advanced Materials, Volume 37, Issue 52, December 29, 2025.Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...
