Global minimality of the degree-one Ginzburg-Landau vortex solution in the unit ball in dimensions
Radu Ignat, Luc Nguyen
We consider the problem of minimizing the Ginzburg-Landau functional among -valued maps from the unit ball with vortex boundary condition $u(…
Mountain pass for the Ginzburg-Landau energy in a strip: solitons and solitonic vortices
Amandine Aftalion, Luc Nguyen
Motivated by recent experiments, we study critical points of the Ginzburg-Landau energy in an infinite strip where phase imprinting is applied to half of the domain. We prove that…
Zero-homogeneous and -equivariant critical points of the Oseen-Frank energy with multiple Frank constants
Luc Nguyen
We give an existence and classification result for zero-homogeneous and -equivariant critical points of the Oseen-Frank energy with multiple Frank constants. These critical p…
Minimality of vortex solutions to Ginzburg--Landau type systems for gradient fields in the unit ball in dimension
Radu Ignat, Mickael Nahon, Luc Nguyen
We prove that the degree-one vortex solution is the unique minimizer for the Ginzburg--Landau functional for gradient fields (that is, the Aviles--Giga model) in the unit ball $B^N…
