If two black holes collide does it make a sound? (Gaurav Khanna)

Black hole coalescence− Study of

blackhole mergers and gravity waves using PS3 cluster

Loop Quantum Gravity

Loop Quantum Gravity New outlook on GUT

− Same goal as string theory and M-theory Many different consequences arise from this

theory.− Space and time not continuous− Black holes act like sponges− Old gravitational potential not valid

Divide and Conquer (Jay Wang) AMO Physics

− Ionization and Excitation of Rydberg Atoms due to strong laser pulses

Lambert-W function

Schrodinger Equation Analytical and Numerical Solutions Time dependent and independent Principle of Superpostion and Implications

This guy just keeps making waves.(Amit Tandon)

Experimental and Computational Fluid Dynamics

− Small scale turbulence to sub-mesoscale mixing layers and eddies

− Weather in a tank

Modeling Advection Diffusion Simple models

− Random walk simulates diffusion while a velocity field simulates advection

More Complicated model

− Advection Diffusion Equation

Most Complicate

− Lagrangian Coherent Structure

BOOM! (Robert Fisher) Supernova

− Primary interest− Great video

Physics of Interstellar Medium− GMC's

GMC shocks Question from last

time? Equations for

conservation

Quarky (Grant O'Rielly) Pion Photo-Production

− Charged Pion production

− Pion production from a polarized target

Pion Photo-Production Quarks

− Up, Down, Charm, Strange, bottom, Top

− And their anti counterpart

Quantum Chromodynamic Lagrangian
