Inverse Design Schemes for Light Propagation in Synthetic Media with Self-Induced Response

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: The traditional approach to realizing a device typically relies on familiar materials and geometries, guided by some derivative notions about the underlying physical mechanisms. Recently, the confluence of additive manufacturing, computer numerical control (CNC) machining and advanced computational paradigms such as inverse design is poised … Read more

Electronic Feedback Loop Sustaining Magnetic Resonance

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Resonance is a phenomenon where amplitude increases when the frequency of a periodic external applied force is close to the natural frequency of a system. The driving force adds energy into the system increasing the amplitude indefinitely unless there is damming, like friction, removing energy … Read more

Molecular Simulation of DNA Packaging into the Phi29 Bacteriophage

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Viruses exist as a protein shell called a capsid. It encloses single or double stranded DNA which codes for the virus elements. In order to reproduce and survive, a virus tightly packages its genetic material then ejects it into a host cell. The infected cell, … Read more

Effects of Chain Length on the Structure and Dynamics of Polymer Composites

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: We use molecular dynamics simulations to study the effect of chain length on the properties of polymer-nanoparticle (NP) composites. We show that polymers slightly elongate near the NP interface and chains tend to align their longest axis with the NP interface. The effect of NP … Read more

Effects of Star-Polymer Confirmations on Polymer Dynamics

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Polymers and polymer-nanocomposites are ubiquitous in the world of material science. Polymeric materials often exhibit properties that make them ideal for a broad range of applications, from cosmetics, to transportation and healthcare. One of the most important properties for processing polymer materials is the glass … Read more

Thermalization Process in a Multimode Nonlinear Photonic Network

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: The thermalization process and the nature of the equilibrium state of an optical beam launched in a multimode nonlinear photonic network is a problem with far-reaching technological applications. Examples range from the design of high-power multimode sources, to beam self-cleaning (condensation) effects in fiber optics. … Read more

Determining the Recombination Rates of Solar Cell Materials

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: A major goal in the field of solar technology is to find semiconductors that can be used to make solar panels that are cheaper or more efficient than solar panels on the market. One of the properties of a material that indicates whether the semiconductor … Read more

Clustering of Rigid Fibers in a Conical Taylor-Couette Flow

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Suspensions of non-spherical particles in fluid flows are present in a number of natural and industrial processes, including blood flow in the human vascular system, ice crystal motion in atmospheric clouds, and the optimization of pulp- and paper-making techniques. However, a more fundamental theoretical framework … Read more

Three-Body Collisions of Binary Stars with Field Stars

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: The present work seeks to gain an understanding of the topology of the planar gravitational three-body problem for equal masses and to apply the results to its molecular equivalent. The three-body problem is notorious for its complexity of solutions that provide insight into the motion … Read more

The Levi-Civita Transform in Two and Three Bodies

by

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: The Gravitational N-Body problem is a problem in physics to predict the motions of N particles interacting gravitationally. For N<3, there exist exact solutions which are easy to compute for all time, given initial conditions. However, for N>2, such solutions do not exist. To quickly … Read more
