Tuning and Switching a Plasmonic Quantum Dot Sandwich in a Nematic Line Defect
Haridas Mundoor, Ghadah. H. Sheetah, Sungoh Park +3
We study the quantum-mechanical effects arising in a single semiconductor core/shell quantum dot controllably sandwiched between two plasmonic nanorods. Control over the position a…
Collective behavior of active topological solitons, knotted streamlines, and transport of cargo in liquid crystals
Hayley R. O. Sohn, Paul J. Ackerman, Timothy J. Boyle +3
Active colloids and liquid crystals are capable of locally converting the macroscopically-supplied energy into directional motion and promise a host of new applications, ranging fr…
Liquid crystal Skyrmions can swim
Paul J. Ackerman, Timothy Boyle, Ivan I. Smalyukh
Topologically nontrivial field configurations called "baby skyrmions" behave like particles and give origins to the field of skyrmionics that promises racetrack memory and other te…
Diversity of knot solitons in liquid crystals manifested by linking of preimages in torons and hopfions
P. J. Ackerman, I. I. Smalyukh
Topological solitons are knots in continuous physical fields classified by non-zero Hopf index values. Despite arising in theories that span many branches of physics, from elementa…
Plasmon-Exciton Interactions Probed Using Spatial Coentrapment of Nanoparticles by Topological Singularities
P. J. Ackerman, Haridas Mundoor, I. I. Smalyukh +1
We study plasmon-exciton interaction by using topological singularities to spatially confine, selectively deliver, cotrap and optically probe colloidal semiconductor and plasmonic…
Reversal of Helicoidal Twist Handedness Near Point Defects of Confined Chiral Liquid Crystals
P. J. Ackerman, I. I. Smalyukh
Handedness of the director twist in cholesteric liquid crystals is commonly assumed to be the same throughout the medium, determined solely by the chirality of constituent molecule…
