Smoothed asymptotics: from number theory to QFT (2024)
Journal Article
Padilla, A., & Smith, R. G. C. (2024). Smoothed asymptotics: from number theory to QFT. Physical Review D, 110(2), Article 025010. https://doi.org/10.1103/PhysRevD.110.025010

Inspired by the method of smoothed asymptotics developed by Terence Tao, we introduce a new ultraviolet regularisation scheme for loop integrals in quantum field theory which we call η regularisation. This reveals a connection between the elimination... Read More about Smoothed asymptotics: from number theory to QFT.

Rydberg superatoms: An artificial quantum system for quantum information processing and quantum optics (2024)
Journal Article
Shao, X.-Q., Su, S.-L., Li, L., Nath, R., Wu, J.-H., & Li, W. (in press). Rydberg superatoms: An artificial quantum system for quantum information processing and quantum optics. Applied Physics Reviews,

Dense atom ensembles with Rydberg excitations display intriguing collective effects mediated by their strong, long-range dipole-dipole interactions. These collective effects, often modeled using Rydberg superatoms, have gained significant attention a...

Damping Wing-Like Features in the Stacked Ly𝛼 Forest: Potential Neutral Hydrogen Islands at 𝑧 < 6 (2024)
Journal Article

Monthly Notices of the Royal Astronomical Society: Letters, 533(1), L49–L56. https://doi.org/10.1093/mnrasl/slae061

Recent quasar absorption line observations suggest that reionization may end as late as z ≈ 5.3. As a means to search for large neutral hydrogen islands at z &amp;lt; 6, we revisit long dark gaps in the Lyβ forest in VLT/X-Shooter and Keck/ESI quasar...

We have estimated the mass of metals in the molecular gas in 13 dusty star-forming galaxies at z ∼ 4 in which the gas, based on previous observations, lies in a cold rotating disk. We estimated the metal masses using either the submillimetre line or... Read More about Metal factories in the early universe.

Stellar and black hole feedback heat and disperse surrounding cold gas clouds, launching gas flows off circumnuclear and galactic disks, producing a dynamic interstellar medium. On large scales bordering the cosmic web, feedback drives enriched gas o...

Reconsidering the dynamical states of galaxy clusters using PCA and UMAP (2024)
Journal Article

Numerous metrics exist to quantify the dynamical state of galaxy clusters, both observationally and within simulations. Many of these correlate strongly with one another, but it is not clear whether all of these measures probe the same intrinsic prop...

Monthly Notices of the Royal Astronomical Society, 532(2), 1646–1658. https://doi.org/10.1093/mnras/stae1530

Spectra of the highest redshift galaxies taken with JWST are now allowing us to see into the heart of the reionization epoch. Many of these observed galaxies exhibit strong damping wing absorption redward of their Lyman-α emission. These observations...

Shock wave generation and propagation in dissipative and nonlocal nonlinear Rydberg media (2024)
Journal Article
Qin, L., Hang, C., Huang, G., & Li, W. (in press). Shock wave generation and propagation in dissipative and nonlocal nonlinear Rydberg media. Physical Review A,

We investigate the generation of optical shock waves in strongly interacting Rydberg atomic gases with a spatially homogeneous dissipative potential. The Rydberg atom interaction induces an optical nonlocal nonlinearity. We focus on local nonlinear (...
