Anomalous dynamics in tracer-particle motions in an electrohydrodynamically driven oil-in-oil system
Somayeh Khajehpour Tadavani, Anand Yethiraj
We characterize the super-diffusive dynamics of tracer particles in an electrohydrodynamically driven emulsion of oil droplets in an immiscible oil medium, where the amplitude and…
Dynamics and complex formation in charged and uncharged Ficoll70 solutions
Swomitra Palit, Anand Yethiraj
We apply pulsed-field-gradient NMR (PFG NMR) technique to measure the translational diffusion for both uncharged and charged polysaccharide (Ficoll70) in water. Analysis of the dat…
Contrasting the dynamics of elastic and non-elastic deformations across an experimental colloidal Martensitic transition
Saswati Ganguly, Priti S. Mohanty, Peter Schurtenberger +2
We present a framework to segregate the roles of elastic and non-elastic deformations in the examination of real-space experiments of solid-solid Martensitic transitions. The Marte…
Electric-field-induced turbulent energy cascade in an oil-in-oil emulsion
Atul Varshney, Mayur Sathe, Shankar Ghosh +3
We observe electro-hydrodynamically driven turbulent flows at low Reynolds numbers in a two-fluid emulsion consisting of micron-scale droplets. In the presence of electric fields,…
Clusters in sedimentation equilibrium for an experimental hard-sphere-plus-dipolar Brownian colloidal system
Hugh D. Newman, Anand Yethiraj
In this work, we use structure and dynamics in sedimentation equilibrium, in the presence of gravity, to examine, confocal microscopy, a Brownian colloidal system in the pres…
Dynamics, crystallization and structures in colloid spin coating
Moorthi Pichumani, Payam Bagheri, Kristin M. Poduska +2
Spin coating is an out-of-equilibrium technique for producing polymer films and colloidal crystals quickly and reproducibly. In this review, we present an overview of theoretical a…
Diffusion NMR study of complex formation in membrane-associated peptides
Suliman Barhoum, Valerie Booth, Anand Yethiraj
Pulsed-field-gradient nuclear magnetic resonance (PFG-NMR) is used to obtain the true hydrodynamic size of complexes of peptides with sodium dodecyl sulfate SDS micelles. The pepti…
Effect of order-parameter fluctuations on the Halperin-Lubensky-Ma first-order transition in superconductors and liquid crystals
Igor F. Herbut, Anand Yethiraj, John Bechhoefer
We show that order-parameter fluctuations in a good type-I superconductor or a liquid crystal always increase the size of the first-order transition. This behavior is eventually ch…
External-field-induced tricritical point in a fluctuation-driven nematic-smectic-A transition
Ranjan Mukhopadhyay, Anand Yethiraj, John Bechhoefer
We study theoretically the effect of an external field on the nematic-smectic-A (NA) transition close to the tricritical point, where fluctuation effects govern the qualitative beh…
