Two-dimensional skyrmions and other solitonic structures in confinement-frustrated chiral nematics
Paul J. Ackerman, Rahul P. Trivedi, Bohdan Senyuk +2
We explore spatially localized solitonic configurations of a director field, generated using optical realignment and laser-induced heating, in frustrated chiral nematic liquid crys…
Reconfigurable interactions and three-dimensional patterning of colloidal particles and defects in lamellar soft media
Rahul P. Trivedi, Ivan I. Klevets, Bohdan Senyuk +2
Colloidal systems find important applications ranging from fabrication of photonic crystals to direct probing of phenomena typically encountered in atomic crystals and glasses. New…
Optical Microscopy of Soft Matter Systems
Taewoo Lee, Bohdan Senyuk, Rahul P. Trivedi +1
The fast-growing field of soft matter research requires increasingly sophisticated tools for experimental studies. One of the oldest and most widely used tools to study soft matter…
Three dimensional optical manipulation and structural imaging of soft materials by use of laser tweezers and multimodal nonlinear microscopy
Rahul P. Trivedi, Taewoo Lee, Kris A. Bertness +1
We develop an integrated system of holographic optical trapping and multimodal nonlinear microscopy and perform simultaneous three-dimensional optical manipulation and non-invasive…
Multimodal nonlinear optical polarizing microscopy of long-range molecular order in liquid crystals
Taewoo Lee, Rahul P. Trivedi, Ivan I. Smalyukh
We demonstrate orientation-sensitive multimodal nonlinear optical polarizing microscopy capable of probing orientational, polar, and biaxial features of mesomorphic ordering in sof…
