Journal Article
Ruttley, D. K., Guttridge, A., Hepworth, T. R., & Cornish, S. L. (2024). Enhanced Quantum Control of Individual Ultracold Molecules Using Optical Tweezer Arrays. PRX Quantum, 5(2), Article 020333. https://doi.org/10.1103/prxquantum.5.020333

Control over the quantum states of individual molecules is crucial in the quest to harness their rich internal structure and dipolar interactions for applications in quantum science. In this paper, we develop a toolbox of techniques for the control a... Read More about Enhanced Quantum Control of Individual Ultracold Molecules Using Optical Tweezer Arrays.

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.

Preparation of 87Rb and 133Cs in the motional ground state of a single optical tweezer (2022)
Journal Article
Spence, S., Brooks, R., Ruttley, D., Guttridge, A., & Cornish, S. (2022). Preparation of 87Rb and 133Cs in the motional ground state of a single optical tweezer. New Journal of Physics, 24, https://doi.org/10.1088/1367-2630/ac95b9

We report simultaneous Raman sideband cooling of a single 87Rb atom and a single 133Cs atom held in separate optical tweezers at 814 nm and 938 nm, respectively. Starting from outside the Lamb-Dicke regime, after 45 ms of cooling we measure probabili... Read More about Preparation of 87Rb and 133Cs in the motional ground state of a single optical tweezer.

Optical effects of domain walls (2022)
Journal Article

Domain walls arise in theories where there is spontaneous symmetry breaking of a discrete symmetry such as ZN and are a feature of many BSM models. In this work we consider the possibility of detecting domain walls through their optical effects and s... Read More about Optical effects of domain walls.

Central instanton production (2022)
Journal Article

We study the central production of QCD instantons at hadron colliders in events with two large rapidity gaps. These gaps in rapidity are formed by either Pomeron or photon exchanges or a combination of the two. The kT-factorization formalism is used... Read More about Central instanton production.

Hunting for QCD instantons at the LHC in events with large rapidity gaps (2021)
Journal Article

We outline a strategy of how to search for QCD instantons of invariant mass 20–60 GeVin diffractive events in low-luminosity runs at the LHC. We show that, by imposing appropriate selection criteria on the final states, one can select the kinematic r...

QCD instantons are arguably the best motivated yet unobserved nonperturbative effects predicted by the Standard Model. A discovery and detailed study of instanton-generated processes at colliders would provide a new window into the phenomenological e... Read More about Searching for QCD instantons at hadron colliders.
