Unavoidable emergent biaxiality in chiral molecular-colloidal hybrid liquid crystals
Jin-Sheng Wu, Marina Torres Lazaro, Souvik Ghosh +3
Chiral nematic or cholesteric liquid crystals (LCs) are mesophases with long-ranged orientational order featuring a quasi-layered periodicity imparted by a helical configuration bu…
Nemato-elasticity of hybrid molecular-colloidal liquid crystals
B. Senyuk, H. Mundoor, I. I. Smalyukh +1
Colloidal rods immersed in a thermotropic liquid-crystalline solvent are at the basis of so-called hybrid liquid crystals which are characterized by tunable nematic fluidity with s…
Anisotropic electrostatic screening of charged colloids in nematic solvents
Jeffrey C. Everts, Bohdan Senyuk, Haridas Mundoor +2
The physical behaviour of anisotropic charged colloids is determined by their material dielectric anisotropy, affecting colloidal self-assembly, biological function and even out-of…
Self-organized nonlinear gratings for ultrafast nanophotonics
Daniel D. Hickstein, David R. Carlson, Haridas Mundoor +7
Modern nonlinear optical materials allow light of one wavelength be efficiently converted into light at another wavelength. However, designing nonlinear optical materials to operat…
Liquid crystal self-assembly of upconversion nanorods enriched by depletion forces for mesostructured material preparation
Yong Xie, Yuanyuan Li, Guoqing Wei +4
Monodisperse rod-like colloidal particles are known for spontaneously forming both nematic and smectic liquid crystal phases, but their self-assembly was typically exploited from t…
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…
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…
Electric Switching of Fluorescence Decay in Gold-Silica-Dye Nematic Nanocolloids Mediated by Surface Plasmons
Li Jiang, Haridas Mundoor, Qingkun Liu +1
Tunable composite materials with interesting physical behavior can be designed through integrating unique optical properties of solid nanostructures with the facile responses of so…
Imaging of director fields in liquid crystals using stimulated Raman scattering microscopy
Taewoo Lee, Haridas Mundoor, Derek G. Gann +2
We demonstrate an approach for background-free three-dimensional imaging of director fields in liquid crystals using stimulated Raman scattering microscopy. This imaging technique…
Mesostructured composite materials with electrically tunable upconversion properties
Haridas Mundoor, Ivan I Smalyukh
A promising approach of designing mesostructured materials with novel physical behavior is to combine unique optical and electronic properties of solid nanoparticles with long-rang…
Triclinic nematic colloidal crystals from competing elastic and electrostatic interactions
Haridas Mundoor, Bohdan Senyuk, Ivan I. Smalyukh
Self-assembly of nanoparticles can enable composites with pre-designed properties but remains challenged by reproducing structural diversity of atomic and molecular crystals. We co…
Optically and elastically assembled plasmonic nanoantennae for spatially resolved characterization of chemical composition in soft matter systems using surface enhanced spontaneous and stimulated Raman scattering
Haridas Mundoor, Taewoo Lee, Derek G. Gann +4
We present a method to locally probe spatially varying chemical composition of soft matter systems by use of optically controlled and elastically self-assembled plasmonic nanoanten…
