Commensurate States and Pattern Switching via Liquid Crystal Skyrmions Trapped in a Square Lattice
A. Duzgun, C. Nisoli, C. J. O. Reichhardt +1
Using continuum based simulations we show that a rich variety of skyrmion liquid crystal states can be realized in the presence of a periodic obstacle array. As a function of the n…
Understanding Thermal Annealing of Artificial Spin Ice
Xiaoyu Zhang, Yuyang Lao, Joseph Sklenar +6
We have performed a detailed study of thermal annealing of the moment configuration in artificial spin ice. Permalloy (NiFe) artificial spin ice samples were examined…
Ice Rule and Emergent Frustration in Particle Ice and Beyond
Antonio Ortiz-Ambriz, Cristiano Nisoli, Charles Reichhardt +2
Geometric frustration and the ice rule are two concepts that are intimately connected and widespread across condensed matter. The first refers to the inability of a system to satis…
Artificial Spin Ice Phase-Change Memory Resistors
Francesco Caravelli, Gia-Wei Chern, Cristiano Nisoli
We study the implications of the anisotropic magnetic resistance on permalloy nanowires, and in particular on the property of the resistance depending on the type of lattice. We di…
Quenched Dynamics of Artificial Spin Ice: Coarsening versus Kibble-Zurek
A. Libal, A. del Campo, C. Nisoli +2
Artificial spin ices are ideal frustrated model systems in which to explore or design emergent phenomena with unprecedented characterization of the constituent degrees of freedom.…
Skyrmion Spin Ice in Liquid Crystals
Ayhan Duzgun, Cristiano Nisoli
We propose the first Skyrmion Spin Ice, realized via confined, interacting liquid crystal skyrmions. Skyrmions in a chiral nematic liquid crystal behave as quasi-particles that can…
