Absence of critical scaling in the Schelling segregation model

Sam Rifaki

We find no evidence of critical scaling in the Schelling segregation model, in either the Moore neighborhood or its dense-spectrum extension to Chebyshev radii up to ($k…

Rare-event sampling for stochastic dynamics in network systems using cluster updates

Jiazheng Sun, James Moody, Thomas Barthel

Understanding the stochastic evolution in complex networks is a central challenge across physics, biology, engineering, social science, and finance. The most consequential macrosco…

Dynamic critical exponent of the Yang--Lee edge singularity at three loops

Loran Ts. Adzhemyan, Diana A. Davletbaeva, Daniil A. Evdokimov +1

We compute the dynamic critical exponent of the Yang--Lee edge singularity in relaxational dynamics using perturbative renormalization-group methods to the three-loop order. Th…

Information, order, complexity, and entropy in materials including biological systems: a thermodynamic theory based on state variables

Koun Shirai

Entropy plays a central role in thermodynamics, statistical mechanics, information theory, and biology. However, its interpretation becomes increasingly ambiguous when information-…

Critical couplings of two dimensional Ising model on various lattices

Sh. Khachatryan, A. Sedrakyan

We develop a unified fermionic-field formulation of the two-dimensional Ising model on several planar lattices using the Kac--Ward representation. Grassmann fields are associated w…

Nonequilibrium Maxwell-Demon NEMD simulations of transport: I. Extrapolating shear viscosity to the hydrodynamic limit

Hesam Arabzadeh, Brad Lee Holian

We present a Maxwell-Demon nonequilibrium molecular dynamics method for measuring the shear viscosity of a Lennard-Jones fluid. The simulation cell is divided into two regions of w…
