Universal nonequilibrium properties of dissipative rydberg gases (2014)
Journal Article
Marcuzzi, M., Levi, E., Diehl, S., Garrahan, J. P., & Lesanovsky, I. (2014). Universal nonequilibrium properties of dissipative rydberg gases. Physical Review Letters, 113(21), Article 210401. https://doi.org/10.1103/PhysRevLett.113.210401

© 2014 American Physical Society. We investigate the out-of-equilibrium behavior of a dissipative gas of Rydberg atoms that features a dynamical transition between two stationary states characterized by different excitation densities. We determine th... Read More about Universal nonequilibrium properties of dissipative rydberg gases.

Critical assessment of the evidence for striped nanoparticles (2014)
Journal Article
Shankar, S. S., Stirling, J., Lekkas, I., Sweetman, A., Djuranovic, P., Guo, Q., …Moriarty, P. (2014). Critical assessment of the evidence for striped nanoparticles. PLoS ONE, 9(11), Article e108482. https://doi.org/10.1371/journal.pone.0108482

There is now a significant body of literature which reports that stripes form in the ligand shell of suitably functionalised Au nanoparticles. This stripe morphology has been proposed to strongly affect the physicochemical and biochemical properties... Read More about Critical assessment of the evidence for striped nanoparticles.

Effective dynamics of strongly dissipative Rydberg gases (2014)
Journal Article
Marcuzzi, M., Schick, J., Olmos, B., & Lesanovsky, I. (2014). Effective dynamics of strongly dissipative Rydberg gases. Journal of Physics A: Mathematical and Theoretical, 47(48), Article 482001. https://doi.org/10.1088/1751-8113/47/48/482001

We investigate the evolution of interacting Rydberg gases in the limit of strong noise and dissipation. Starting from a description in terms of a Markovian quantum master equation we derive effective equations of motion that govern the dynamics on a...

Constraining disformally coupled scalar fields (2014)
Journal Article
Brax, P., & Burrage, C. (2014). Constraining disformally coupled scalar fields. Physical Review D, D90(10), Article 104009. https://doi.org/10.1103/PhysRevD.90.104009

Light scalar fields can naturally couple disformally to matter fields. Static, nonrelativistic sources do not generate a classical field profile for a disformally coupled scalar, and so such scalars are free from the constraints on the existence of f...

Versatile cold atom source for multi-species experiments (2014)
Journal Article
Paris-Mandoki, A., Jones, M. D., Nute, J., Wu, J., Warriar, S., & Hackermüller, L. (2014). Versatile cold atom source for multi-species experiments. Review of Scientific Instruments, 85(11), Article 113103. https://doi.org/10.1063/1.4900577

We present a dual-species oven and Zeeman slower setup capable of producing slow, high-flux atomic beams for loading magneto-optical traps. Our compact and versatile system is based on electronic switching between different magnetic field profiles an... Read More about Versatile cold atom source for multi-species experiments.

Sussing merger trees: the impact of halo merger trees on galaxy properties in a semi-analytic model (2014)
Journal Article
Lee, J., Yi, S. K., Elahi, P. J., Thomas, P. A., Pearce, F. R., Behroozi, P., …Tweed, D. (2014). Sussing merger trees: the impact of halo merger trees on galaxy properties in a semi-analytic model. Monthly Notices of the Royal Astronomical Society, 445(4), https://doi.org/10.1093/mnras/stu2039

A halo merger tree forms the essential backbone of a semi-analytic model for galaxy formation and evolution. Recent studies have pointed out that extracting merger trees from numerical simulations of structure formation is non-trivial; different tree...
