Curvature as a guiding field for patterns in thin block copolymer films
Giang Thi Vu, Anabella A. Abate, Leopoldo R. Gómez +4
Experimental data on thin films of cylinder-forming block copolymers (BC) -- free-standing BC membranes as well as supported BC films -- strongly suggest that the local orientation…
Thermal Properties of Vortices on Curved Surfaces
Leopoldo R. Gómez, Nicolás A. García, Daniel A. Vega +1
We use Monte Carlo simulations to study the finite temperature behavior of vortices in the XY- model for tangent vector order on curved backgrounds. Contrary to naive expectations,…
Pattern formation mechanisms in sphere-forming diblock copolymer thin films
Leopoldo R. Gómez, Nicolás A. García, Richard A. Register +1
The order-disorder transition of a sphere-forming block copolymer thin film was numerically studied through a Cahn-Hilliard model. Simulations show that the fundamental mechanisms…
Phase nucleation in curved space
Leopoldo R. Gomez, Nicolas A. Garcia, Vincenzo Vitelli +2
Nucleation and growth is the dominant relaxation mechanism driving first order phase transitions. In two-dimensional at systems nucleation has been applied to a wide range of probl…
Crystallization Dynamics on Curved Surfaces
Nicolas A. Garcia, Richard A. Register, Daniel A. Vega +1
We study the evolution from a liquid to a crystal phase in two-dimensional curved space. At early times, while crystal seeds grow preferentially in regions of low curvature, the la…
Soliton attenuation and emergent hydrodynamics in fragile matter
N. Upadhyaya, L. R. Gomez, V. Vitelli
Disordered packings of soft grains are fragile mechanical systems that loose rigidity upon lowering the external pressure towards zero. At zero pressure, we find that any infinites…
Uniform Shock Waves in Disordered Granular Matter
L. R. Gomez, A. M. Turner, V. Vitelli
The confining pressure is perhaps the most important parameter controlling the properties of granular matter. Strongly compressed granular media are, in many respects, simple s…
Shocks near Jamming
Leopoldo R. Gomez, Ari M. Turner, Martin van Hecke +1
Non-linear sound is an extreme phenomenon typically observed in solids after violent explosions. But granular media are different. Right when they jam, these fragile and disordered…
Amorphous Precursors of Crystallization during Spinodal Decomposition
Leopoldo R. Gomez, Daniel A. Vega
A general Landau's free energy functional is used to study the dynamics of crystallization during liquid-solid Spinodal Decomposition (SD). The strong length scale selectivity impo…
