Extended regime of nematic order in an interacting monomer-dimer model of Heilmann and Lieb

Qidong He

We revisit a two-dimensional model of liquid crystals introduced by Heilmann--Lieb (1979), which consists of dimers on the square lattice at chemical potential , interacting via…

Liquid-vapor transition in a model of a continuum particle system with finite-range modified Kac pair potential

Qidong He, Ian Jauslin, Joel Lebowitz +1

We prove the existence of a phase transition in dimension in a continuum particle system interacting with a pair potential containing a modified attractive Kac potential of r…

Upper bounds for the connective constant of weighted self-avoiding walks

Qidong He

Building on a work by Alm, we consider a model of weighted self-avoiding walks on a lattice and develop a method for computing upper bounds on the corresponding weighted connective…
