Collectively encoded Rydberg qubit (2021)
Journal Article
Spong, N. L., Jiao, Y., Hughes, O. D., Weatherill, K. J., Lesanovsky, I., & Adams, C. S. (2021). Collectively encoded Rydberg qubit. Physical Review Letters, 127(6), Article 063604. https://doi.org/10.1103/physrevlett.127.063604

We demonstrate a collectively-encoded qubit based on a single Rydberg excitation stored in an ensemble of N entangled atoms. Qubit rotations are performed by applying microwave fields that drive excitations between Rydberg states. Coherent read-out i... Read More about Collectively encoded Rydberg qubit.

An optimal non-linear method for simulating relic neutrinos (2021)
Journal Article
Elbers, W., Frenk, C. S., Jenkins, A., Li, B., & Pascoli, S. (2021). An optimal non-linear method for simulating relic neutrinos. Monthly Notices of the Royal Astronomical Society, 507(2), 2614-2631. https://doi.org/10.1093/mnras/stab2260

Cosmology places the strongest current limits on the sum of neutrino masses. Future observations will further improve the sensitivity and this will require accurate cosmological simulations to quantify possible systematic uncertainties and to make pr...

Collisional cooling of primordial and interstellar media by H2 (2021)
Journal Article
Flower, D., Pineau des Forêts, G., Hily-Blant, P., Faure, A., Lique, F., & González-Lezana, T. (2021). Collisional cooling of primordial and interstellar media by H2. Monthly Notices of the Royal Astronomical Society, 507(3), 3564-3571. https://doi.org/10.1093/mnras/stab2272

We have computed the rate of collisional cooling of a gas by H2 molecules under conditions appropriate to the primordial and interstellar media. We incorporated the results of recent calculations of the rate coefficients for collisional excitation of... Read More about Collisional cooling of primordial and interstellar media by H2.

DynDen: Assessing convergence of molecular dynamics simulations of interfaces (2021)
Journal Article
Degiacomi, M. T., Tian, S., Greenwell, H. C., & Erastova, V. (2021). DynDen: Assessing convergence of molecular dynamics simulations of interfaces. Computer Physics Communications, 269, Article 108126. https://doi.org/10.1016/j.cpc.2021.108126

Molecular dynamics is a simulation technique used to predict the physical properties of systems based on their chemical structure and evolution of their atomic constituents. For these predictions to be reliable, it is critical that the simulation has... Read More about DynDen: Assessing convergence of molecular dynamics simulations of interfaces.

Constraining cosmology with weak lensing voids (2021)
Journal Article
Davies, C. T., Cautun, M., Giblin, B., Li, B., Harnois-Déraps, J., & Cai, Y.-C. (2021). Constraining cosmology with weak lensing voids. Monthly Notices of the Royal Astronomical Society, 507(2), 2267-2282. https://doi.org/10.1093/mnras/stab2251

Upcoming surveys such as LSST and EUCLID will significantly improve the power of weak lensing as a cosmological probe. To maximize the information that can be extracted from these surveys, it is important to explore novel statistics that complement s... Read More about Constraining cosmology with weak lensing voids.

Topological defect-mediated skyrmion annihilation in three dimensions (2021)
Journal Article
Birch, M. T., Cortés-Ortuño, D., Khanh, N. D., Seki, S., Štefančič, A., Balakrishnan, G., Tokura, Y., & Hatton, P. D. (2021). Topological defect-mediated skyrmion annihilation in three dimensions. Communications Physics, 4(1), https://doi.org/10.1038/s42005-021-00675-4

The creation and annihilation of magnetic skyrmions are mediated by three-dimensional topological defects known as Bloch points. Investigation of such dynamical processes is important both for understanding the emergence of exotic topological spin te...

Aims. We investigate the contribution of shot-noise and sample variance to uncertainties in the cosmological parameter constraints inferred from cluster number counts, in the context of the Euclid survey. Methods. By analysing 1000 Euclid-like light... Read More about Euclid : Effects of sample covariance on the number counts of galaxy clusters.

Star formation histories of Coma cluster galaxies matched to simulated orbits hint at quenching around first pericenter (2021)

Context. The star formation in galaxies in present-day clusters has almost entirely been shut down, but the exact mechanism that quenched these galaxies is still uncertain. Aims. By tracing the orbital and star formation histories of galaxies within...

Capillary Interfacial Tension in Active Phase Separation (2021)
Journal Article

In passive fluid-fluid phase separation, a single interfacial tension sets both the capillary fluctuations of the interface and the rate of Ostwald ripening. We show that these phenomena are governed by two different tensions in active systems, and c... Read More about Capillary Interfacial Tension in Active Phase Separation.
