Using the Goodman Spectrograph (SOAR 4m telescope) buffer concentration. At intermediate salt concentrations (15 - 60 and the SMARTS 0.9m telescope, we were able to collect time-series mM), the system formed spherically-shaped micelles, exhibiting a photometry and spectra for four of the EREBOS targets. We wrote steady growth in the hydrodynamic radius (Rh) from 10 to 21 nm, with photometry and spectral analysis code in Python to extract light increasing PBS concentration. Interestingly, higher salt concentrations curves and orbital velocities.

We start by forming a magneto-optical in AdS(4)/CFT(3) trap (MOT), which consists of a high-density, low-kinetic energy Scattering amplitudes are observables that help us probe our theories sample of atoms, in this case 85Rb. We then perform an optical toss of fundamental particle interactions in high energy physics. Gluons, on the MOT while probing the sample with another laser beam, the being the exchange particles associated with the strong nuclear Raman laser beam. A sequence of Raman laser pulses creates an force, which holds quarks together to form protons, are abundant atom interferometer. The interference represents a high-precision byproducts of proton-proton collisions. Thus, knowing how to measurement of the magnetic splitting of the atomic energy levels, calculate gluon scattering amplitudes for large gluon assemblies is which can be used to measure the magnetic field gradient. We especially useful for identifying the byproducts of collisions at proton- also magnetically shield the experiment to reduce magnetic noise, proton colliders, like the Large Hadron Collider. Traditionally, Feynman implement a phase lock for the Raman laser frequency, improve diagrams have been used to calculate such scattering amplitudes the loading time of the MOT, and show two Raman spectra taken by summing over all the possible ways a certain particle assembly simultaneously via a dark spot MOT experiment. The current can interact. However, the number of Feynman diagrams one has overarching goal for the experiment is to be able to take data with to consider increases faster than factorially with the total number T^3 sensitivity instead of the T^2 sensitivity found in current atom of particles in the assembly. Fortunately, recursion relations have interferometers. recently simplified these calculations significantly.

We use recursion to useful tools for probing matter to better understand its fundamental properties governed by the strong interaction. As the spectroscopy of 2 2016 Quadrennial Physics Congress (PhysCon) Poster Abstracts the excited states of nucleons enters a new era of precision ushered For example, if strong enough coupling is attained with the spin in by improved experiments at Jefferson Lab and other facilities ensemble in a ruby crystal that has a small enough linewidth, this around the world, traditional partial-wave analysis methods must system could serve in a quantum computer as a quantum memory. be adjusted accordingly. In this poster, we present a rigorous set of Previous research has shown strong coupling to spin ensembles, statistical tools and techniques that we implemented; most notably, but achieving a smaller spin linewidth is required to create quantum the LASSO method, which serves for the selection of the simplest memory devices. This study examines the coupling between a spin model, allowing us to avoid over fitting. In the case of establishing the ensemble and a double post reentrant three dimensional copper spectrum of exited baryons, it avoids overpopulation of the spectrum cavity, which could take advantage of its higher mode volume and thus the occurrence of false-positives. This is a prerequisite and a more constant magnetic field through the ruby volume to to reliably compare theories like lattice QCD or quark models to achieve higher coupling and a smaller spin linewidth. Measuring the experiments.Here, we demonstrate the principle by simultaneously transmittance through the cavity, the change in quality factor, Q, and fitting three observables in neutral pion photo-production, such as resonant frequency of the cavity indicate coupling
