ENTROPY – Volume: 15; Issue: 9; Pages: 3931-3940; DOI: 10.3390/e15093931
We investigate solutions of a generalized diffusion equation that contains nonlinear terms in the presence of external forces and reaction terms. The solutions found here can have a compact or long tail behavior and can […]

APPLIED PHYSICS LETTERS – Volume: 102; Issue: 23; Article Number: 231903; DOI: 10.1063/1.4809924
The surface displacement produced by radiation pressure and electrostriction forces is investigated considering the commonly accepted theories proposed by Minkowski and Abraham for the energy-momentum tensor. The contributions are […]

PHYSICAL REVIEW LETTERS – Volume: 110; Issue: 5; Article Number: 057801; DOI: 10.1103/PhysRevLett.110.057801
We study the pattern formation of a chiral nematic liquid crystal under a wetting transition. In the isotropic-liquid crystal transition, a surface-enhanced effect happens and a thin liquid crystal layer forms at the […]
