Reorientational solitons in nematic liquid crystals with modulated alignment
Filip A. Sala, Noel F. Smyth, Urszula A. Laudyn +3
In uniaxial soft matter with a reorientational nonlinearity, such as nematic liquid crystals, a light beam in the extraordinary polarization walks off its wavevector due to birefri…
A Twisted -algebra formulation of Quantum Cosmology with application to the Bianchi I model
Marcos Rosenbaum, J. David Vergara, Román Juárez +1
A twisted - algebra of the extended (noncommutative) Heisenberg-Weyl group has been constructed which takes into account the Uncertainty Principle for coordina…
A chemotactic model for interaction of antagonistic microflora colonies: front asymptotics and numerical simulations
Carlos Malaga, Antonmaria Minzoni, Ramon G. Plaza +1
This paper studies a two-dimensional chemotactic model for two species in which one of them produces a chemo-repellent for the other. It is shown asymptotically and numerically how…
Lattice vortices induced by noncommutativity
A. A. Minzoni, L. R. Juarez, M. Rosenbaum
We show that the Moyal *-product on the algebra of fields induces an effective lattice structure on vortex dynamics which can be explicitly constructed using recent asymptotic resu…
Vector vortex solitons in nematic liquid crystals
Zhiyong Xu, Noel F. Smyth, Antonmaria A. Minzoni +1
We analyze the existence and stability of two-component vector solitons in nematic liquid crystals for which one of the components carries angular momentum and describes a vortex b…
Variational Approach to Gaussian Approximate Coherent States: Quantum Mechanics and Minisuperspace Field Theory
A. A. Minzoni, Marcos Rosenbaum, Michael P. Ryan
This paper has a dual purpose. One aim is to study the evolution of coherent states in ordinary quantum mechanics. This is done by means of a Hamiltonian approach to the evolution…
Quasi-Exactly-Solvable Many-Body Problems
A. Minzoni, M. Rosenbaum, A. Turbiner
Explicit examples of quasi-exactly-solvable -body problems on the line are presented. These are related to the hidden algebra , and they are of two types -- containing up…
