Derivation of the Field Due to a Magnetic Dipole Without Use of the Vector Potential (2022)
Journal Article
Proctor, J. E., & Gould, H. T. (2023). Derivation of the Field Due to a Magnetic Dipole Without Use of the Vector Potential. Physics Teacher, 61(1), 40-42. https://doi.org/10.1119/5.0077127

The mathematical form of the magnetic field due to a current loop, and the fact that it is identical to the electric field due to an electric dipole in the far field, are fundamental to our understanding of electromagnetism. While undergraduate level... Read More about Derivation of the Field Due to a Magnetic Dipole Without Use of the Vector Potential.

Krypton and the fundamental flaw of the Lennard-Jones Potential (2022)
Journal Article
Pruteanu, C., Loveday, J., Ackland, G., & Proctor, J. (2022). Krypton and the fundamental flaw of the Lennard-Jones Potential. Journal of Physical Chemistry Letters, 13(35), 8284-8289. https://doi.org/10.1021/acs.jpclett.2c02004

We have performed a series of neutron scattering experiments on supercritical krypton. Our data and analysis allow us to characterize the Frenkel line crossover in this model monatomic fluid. The data from our measurements was analyzed using Empirica... Read More about Krypton and the fundamental flaw of the Lennard-Jones Potential.

Phase diagram of ethane above 300 K (2022)
Journal Article
Proctor, J., Spender, J., & Gould, H. (2022). Phase diagram of ethane above 300 K. Journal of Physical Chemistry C, 126(26), 10792-10799. https://doi.org/10.1021/acs.jpcc.2c00875

We have measured the melting curve of ethane from 300 to 450 K. Our results indicate that to describe all melting curve data above the triple point, it is necessary to account for a kink in the melting curve where the phase III–phase IV solid–solid t...

Characterization of the high-pressure and high-temperature phase diagram and equation of state of chromium. (2022)
Journal Article
Anzellini, S., Errandonea, D., Burakovsky, L., Proctor, J., Turnbull, R., & Beavers, C. (2022). Characterization of the high-pressure and high-temperature phase diagram and equation of state of chromium. Scientific reports, 12(1), 6727. https://doi.org/10.1038/s41598-022-10523-2

The high-pressure and high-temperature phase diagram of chromium has been investigated both experimentally (in situ), using a laser-heated diamond-anvil cell technique coupled with synchrotron powder X-ray diffraction, and theoretically, using ab ini...

High pressure photoluminescence of bismuth-doped yttria-alumina-silica glass (2022)
Journal Article
Hughes, M., McMaster, R., Proctor, J., Hewak, D., Suzuki, T., & Oshidi, Y. (2022). High pressure photoluminescence of bismuth-doped yttria-alumina-silica glass. High Pressure Research, https://doi.org/10.1080/08957959.2022.2044031

We report the effects of high pressure, up to 10.45 GPa, on the photoluminescence of Bi-doped yttria-alumina-silica (Bi:YAlSi) glass under 532 nm excitation. We identify three emission bands attributed to Bi3+, Bi+ and the controversial NIR emitting... Read More about High pressure photoluminescence of bismuth-doped yttria-alumina-silica glass.
