Journal Article
Rivero-Rodríguez, J. F., McClements, K. G., Fitzgerald, M., Sharapov, S. E., Cecconello, M., Crocker, N. A., Dolby, I., Dreval, M., Fil, N., Galdón-Quiroga, J., García-Muñoz, M., Blackmore, S., Heidbrink, W., Henderson, S., Jackson, A., Kappatou, A., Keeling, D., Liu, D., Liu, Y. Q., Michael, C., …the MAST-U Team. (2024). Overview of fast particle experiments in the first MAST Upgrade experimental campaigns. Nuclear Fusion, 64(8), Article 086025. https://doi.org/10.1088/1741-4326/ad56a2

MAST-U is equipped with on-axis and off-axis neutral beam injectors (NBI), and these external sources of super-Alfvénic deuterium fast-ions provide opportunities for studying a wide range of phenomena relevant to the physics of alpha-particles in bur...

Large dynamic scissoring mode displacements coupled to band gap opening in the cubic phase of the methylammonium lead halide perovskites. (2024)
Journal Article
Bird, T. A., Chen, J., Songvilay, M., Stock, C., Wharmby, M. T., Bristowe, N. C., & Senn, M. S. (2024). Large dynamic scissoring mode displacements coupled to band gap opening in the cubic phase of the methylammonium lead halide perovskites. Journal of Physics: Condensed Matter, 36(41), Article 415402. https://doi.org/10.1088/1361-648X/ad5b44

Hybrid perovskites are a rapidly growing research area, having reached photovoltaic power conversion efficiencies of over 25 %. There is a increasing consensus that the structures of these materials, and hence their electronic structures, can not be...

Simultaneous multiband radio-frequency detection using high-orbital-angular-momentum states in a Rydberg-atom receiver (2024)
Journal Article
Allinson, G., Jamieson, M. J., Mackellar, A. R., Downes, L. A., Adams, C. S., & Weatherill, K. J. (2024). Simultaneous multiband radio-frequency detection using high-orbital-angular-momentum states in a Rydberg-atom receiver. Physical Review Research, 6(2), Article 023317. https://doi.org/10.1103/physrevresearch.6.023317

We demonstrate simultaneous detection of radio-frequency (rf) fields ranging from the very high-frequency (VHF) band (128 MHz) to terahertz frequencies (0.61 THz) using high-orbital-angular-momentum (ℓ) states in a caesium Rydberg-atom receiver. rf f...

MIDIS: Unveiling the Role of Strong Hα Emitters During the Epoch of Reionization with JWST (2024)
Journal Article
Rinaldi, P., Caputi, K. I., Iani, E., Costantin, L., Gillman, S., Perez Gonzalez, P. G., Östlin, G., Colina, L., Greve, T. R., Nørgard-Nielsen, H. U., Wright, G. S., Álvarez-Márquez, J., Eckart, A., García-Marín, M., Hjorth, J., Ilbert, O., Kendrew, S., Labiano, A., Le Fèvre, O., Pye, J., …Dayal, P. (2024). MIDIS: Unveiling the Role of Strong Hα Emitters During the Epoch of Reionization with JWST. Astrophysical Journal, 969(1), 12. https://doi.org/10.3847/1538-4357/ad4147

By using an ultradeep JWST/MIRI image at 5.6 μm in the Hubble eXtreme Deep Field, we constrain the role of strong Hα emitters (HAEs) during “cosmic reionization” at z ≃ 7-8. Our sample of HAEs is comprised of young (<35 Myr) galaxies, except for one...

Training neural networks with universal adiabatic quantum computing (2024)
Journal Article

Role of cosmological gravitational particle production in baryogenesis (2024)
Journal Article
Flores, M. M., & Perez-Gonzalez, Y. F. (2024). Role of cosmological gravitational particle production in baryogenesis. Physical Review D, 109(11), https://doi.org/10.1103/physrevd.109.115017

We investigate the generation of the baryon asymmetry within the framework of cosmological gravitational particle production, employing the Bogoliubov approach. We examine two well-known baryogenesis scenarios, namely baryogenesis in grand unified th... Read More about Role of cosmological gravitational particle production in baryogenesis.
