Multiple complex space-charge structures in unmagnetized low-temperature plasmas arise from ionization phenomena near additional negatively or positively biased electrodes or due to local constraints. Because of their usually spherical form, such structures are called fireballs. If they appear inside hollow grids, they are called inverted fireballs or plasma bubbles. The temporal evolution of such structures is often accompanied by strong plasma instabilities. The dynamics of complex space-charge structures have been investigated by using single spherical grid cathode with an orifice. Langmuir probe and optical emission spectroscopy were used to diagnose the structures. Measurements delivered the axial profiles of the plasma …

Four Derivations Of Schrödinger’S Time Dependent Equation, Sydney Swanson
Four Derivations Of Schrödinger’S Time Dependent Equation, Sydney Swanson
Essential Studies UNDergraduate Showcase
Physics and the natural world have been studied by humans since the first person wondered ‘Why?’ The Schrödinger equation is important because it attempts to describe a relatively new (to us) and unfamiliar part of our universe, behavior of subatomic particles, and helps modern scientists uncover secrets that have proven useful in technology and explaining our origins. The time dependent Schrödinger equation can be derived from various starting points in Classical such as the equation of a wave, the time independent Schrödinger equation, and Hamilton-Jacobi equations. Why Quantum mechanics exists, useful applications, and cases when it fails or is inaccurate …
Computational Techniques For Scattering Amplitudes, Juliano A. Everett
Computational Techniques For Scattering Amplitudes, Juliano A. Everett
Publications and Research
Scattering amplitudes in quantum field theory can be described as the probability of a scattering process to happen within a high energy particle interaction, as well as a bridge between experimental measurements and the prediction of the theory.
In this research project, we explore the Standard Model of Particle Theory, it’s representation in terms of Feynman diagrams and the algebraic formulas associated with each combination.
Using the FeynArts program as a tool for generating Feynman diagrams, we evaluate the expressions of a set of physical processes, and explain why these techniques become necessary to achieve this goal.

Attitude Of Secondary School Students Towards Physics Subject: A Case Of A Secondary School In Moshi Municipality, Erick Makange
Master of Education
This study examined Secondary School students’ attitude towards Physics subject by assessing the factors associated with such attitude. Qualitative research approach with case study design was adopted. The study had four questions; What are the positive factors that affect student’s attitude towards Physics? What are the negative factors that affect student’s attitude towards Physics? What are the effects of the negative attitudes of students towards Physics? To what extent are these factors affecting the attitude of the students towards Physics? The study sample size comprised of two teachers (academic teacher, and Physics teacher) who were purposively sampled; and 12 form …

Kawamoto, Eric, Cosette Holmes, Tiana Cope-Ferland
Querying the Past: LGBTQ Maine Oral History Project Collection
This interview with Eric Kawamoto reveals a journey of self-discovery in Chicago, L.A., Boston, and Portland; an intersection between being Asian American and being queer; and survival of AIDS as a result of reserve. Kawamoto places these personal themes among his account of the LGBTQ+ and Asian American communities’ overarching struggles, like the fight for domestic partnership benefits, representation of Asian American gay men, and spreading awareness about Japanese American internment in California.

This paper reports the measurement of polarized and unpolarized cross sections for the ep→e′p′γ reaction, which is composed of deeply virtual Compton scattering (DVCS) and Bethe-Heitler (BH) processes, at an electron beam energy of 5.88 GeV at the Thomas Jefferson National Accelerator Facility using the Large Acceptance Spectrometer CLAS. The unpolarized cross sections and polarized cross section differences have been measured over broad kinematics, 0.10 < xB < 0.58, 1.0 < Q2 <4.8 GeV2 and 0.09<−t <2.00 GeV2. The results are found to be consistent with previous CLAS data, and these new data are discussed in the framework of the generalized parton distribution approach. Calculations …
