Report

Autor: Campbell, David K., Bouche, Ian, Som, Abhishek, Bishop, David J.

Since its first description in 1948, the Casimir effect has been studied extensively. Standard arguments for its existence hinge on the elimination of certain modes of the electromagnetic field because of the boundary conditions in the Casimir cavity

The Rayleigh-Taylor instability in a binary quantum fluid

Autor: Geng, Yanda, Tao, Junheng, Zhao, Mingshu, Mukherjee, Shouvik, Eckel, Stephen, Campbell, Gretchen K., Spielman, Ian B.

Instabilities, where small fluctuations seed the formation of large-scale structures, govern dynamics in a variety of fluid systems. The Rayleigh-Taylor instability (RTI), present from tabletop to astronomical scales, is an iconic example characteriz

Large Language Models for Medical OSCE Assessment: A Novel Approach to Transcript Analysis

Autor: Shakur, Ameer Hamza, Holcomb, Michael J., Hein, David, Kang, Shinyoung, Dalton, Thomas O., Campbell, Krystle K., Scott, Daniel J., Jamieson, Andrew R.

Grading Objective Structured Clinical Examinations (OSCEs) is a time-consuming and expensive process, traditionally requiring extensive manual effort from human experts. In this study, we explore the potential of Large Language Models (LLMs) to asses

Zeptonewton and Attotesla per Centimeter Metrology With Coupled Oscillators

Autor: Bouche, Ian, Javor, Josh, Som, Abhishek, Campbell, David K., Bishop, David J.

We present the coupled oscillator: a new mechanism for signal amplification with widespread application in metrology. We introduce the mechanical theory of this framework, and support it by way of simulations. We present a particular implementation o

Zigzag materials: selective interchain couplings control the coexistence of one-dimensional physics and deviations from it

Autor: Carmelo, J. M. P., Sacramento, P. D., Stauber, T., Campbell, D. K.

Publikováno v: Physical Review Research 5, 043058 (2023)

The coexistence in the low-temperature spin-conducting phases of the zigzag materials BaCo2V2O8 and SrCo2V2O8 of one-dimensional (1D) physics with important deviations from it is not well understood. The studies of this paper account for an important

Grating magneto-optical traps with complicated level structures

Autor: Barker, D. S., Elgee, P. K., Sitaram, A., Norrgard, E. B., Klimov, N. N., Campbell, G. K., Eckel, S.

We study the forces and optical pumping within grating magneto-optical traps (MOTs) operating on transitions with non-trivial level structure. In contrast to the standard six-beam MOT configuration, rate equation modelling predicts that the asymmetri

Application of Generalized Periodic Anderson Hamiltonians to the Superconducting Nickelates

Autor: Som, Abhishek, Yirga, Nahom K., Campbell, David K.

We study the extent to which a three-dimensional dispersing Periodic Anderson Model (PAM) can explain the emergence of novel superconductivity in the Infinite-Layer Nickelate compounds. By going beyond frequently used 2D models, the 3D dispersing PAM
