Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…
Directed Motion of Liquid Crystal Skyrmions With Oscillating Fields
A. Duzgun, C. Nisoli, C. J. O. Reichhardt +1
Using continuum simulations, we show that under a sinusoidal electric field, liquid crystal skyrmions undergo periodic shape oscillations which produce controlled directed motion.…
Explicit Kink Solutions in Several One-Parameter Family of Higher Order Field Theory Models
Avinash Khare, Ayhan Duzgun, Avadh Saxena
We present several one-parameter family of higher order field theory models some of which admit explicit kink solutions with an exponential tail while others admit explicit kink so…
String Phase in an Artificial Spin Ice
Xiaoyu Zhang, Ayhan Duzgun, Yuyang Lao +13
One-dimensional strings of local excitations are a fascinating feature of the physical behavior of strongly correlated topological quantum matter. Here we study strings of local ex…
Alignment induced re-configurable walls for patterning and assembly of liquid crystal skyrmions
Ayhan Duzgun, Avadh Saxena, Jonathan V. Selinger
Skyrmions have attracted rapidly growing interest due to their topological properties and unique aspects for potential novel applications such as data storage and soft robotics. Th…
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…
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…
Active Brownian particles near straight or curved walls: Pressure and boundary layers
Ayhan Duzgun, Jonathan V. Selinger
Unlike equilibrium systems, active matter is not governed by the conventional laws of thermodynamics. Through a series of analytic calculations and Langevin dynamics simulations, w…
Comparing skyrmions and merons in chiral liquid crystals and magnets
Ayhan Duzgun, Jonathan V. Selinger, Avadh Saxena
When chiral liquid crystals or magnets are subjected to applied fields or other anisotropic environments, the competition between favored twist and anisotropy leads to the formatio…
Dynamic Theory of Polydomain Liquid-Crystal Elastomers
Ayhan Duzgun, Jonathan V. Selinger
When liquid-crystal elastomers are prepared without any alignment, disordered polydomain structures emerge as the materials are cooled into the nematic phase. These polydomain stru…
