Observation of Rydberg blockade due to the charge-dipole interaction between an atom and a polar molecule (2023)
Journal Article
Guttridge, A., Ruttley, D., Baldock, A., González-Férez, R., Sadeghpour, H., Adams, C., & Cornish, S. (2023). Observation of Rydberg blockade due to the charge-dipole interaction between an atom and a polar molecule. Physical Review Letters, 131(1), Article 013401. https://doi.org/10.1103/PhysRevLett.131.013401

We demonstrate Rydberg blockade due to the charge-dipole interaction between a single Rb atom and a single RbCs molecule confined in optical tweezers. The molecule is formed by magnetoassociation of a Rb+Cs atom pair and subsequently transferred to t...

Formation of Ultracold Molecules by Merging Optical Tweezers (2023)
Journal Article
Ruttley, D. K., Guttridge, A., Spence, S., Bird, R. C., Le Sueur, C. R., Hutson, J. M., & Cornish, S. L. (2023). Formation of Ultracold Molecules by Merging Optical Tweezers. Physical Review Letters, 130(22), https://doi.org/10.1103/physrevlett.130.223401

We demonstrate the formation of a single RbCs molecule during the merging of two optical tweezers, one containing a single Rb atom and the other a single Cs atom. Both atoms are initially predominantly in the motional ground states of their respectiv... Read More about Formation of Ultracold Molecules by Merging Optical Tweezers.

Gravitational waves and dark matter from classical scale invariance (2023)
Journal Article
Khoze, V. V., & Milne, D. L. (2023). Gravitational waves and dark matter from classical scale invariance. Physical Review D, 107(9), Article 095012. https://doi.org/10.1103/physrevd.107.095012

In this paper we consider a minimal classically conformal U(1) model of fermionic dark matter. We calculate the one loop effective potential which generates the mass scale quantum mechanically via dimensional transmutation in the spirit of Gildener a...

Searches for QCD instantons with forward proton tagging (2023)
Journal Article
Tasevsky, M., Khoze, V., Milne, D., & Ryskin, M. (2023). Searches for QCD instantons with forward proton tagging. The European Physical Journal C, 83, Article 35. https://doi.org/10.1140/epjc/s10052-023-11178-7

We study the possibility to observe heavy (Minst>60 GeV) QCD instantons at the LHC in events with one or two tagged leading protons including fast simulation of detector and pile-up effects. We show that the expected instanton signal in a single-tagg... Read More about Searches for QCD instantons with forward proton tagging.
