Turbulent ‘stopping plumes’ and plume pinch-off in uniform surroundings (2014)
Journal Article
Kattimeri, A., & Scase, M. M. (2014). Turbulent ‘stopping plumes’ and plume pinch-off in uniform surroundings. Environmental Fluid Mechanics, 15(5), https://doi.org/10.1007/s10652-014-9387-7

Observations of turbulent convection in the environment are of variously sus- tained plume-like flows or intermittent thermal-like flows. At different times of the day the prevailing conditions may change and consequently the observed flow regimes ma...

Entanglement entropy in Fermi gases and Anderson's orthogonality catastrophe (2014)
Journal Article
Ossipov, A. (2014). Entanglement entropy in Fermi gases and Anderson's orthogonality catastrophe. Physical Review Letters, 113(13), Article 130402. https://doi.org/10.1103/PhysRevLett.113.130402

We study the ground-state entanglement entropy of a finite subsystem of size L of an infinite system of noninteracting fermions scattered by a potential of finite range a. We derive a general relation between the scattering matrix and the overlap mat... Read More about Entanglement entropy in Fermi gases and Anderson's orthogonality catastrophe.

Unruh-DeWitt detector response across a Rindler firewall is finite (2014)
Journal Article
Louko, J. (2014). Unruh-DeWitt detector response across a Rindler firewall is finite. Journal of High Energy Physics, 2014(9), https://doi.org/10.1007/JHEP09%282014%29142

We investigate a two-level Unruh-DeWitt detector coupled to a massless scalar field or its proper time derivative in (1 + 1)-dimensional Minkowski spacetime, in a quantum state whose correlation structure across the Rindler horizon mimics the station...

Impurities as a quantum thermometer for a Bose-Einstein condensate (2014)
Journal Article
Sabín, C., White, A., Hackermuller, L., & Fuentes, I. (2014). Impurities as a quantum thermometer for a Bose-Einstein condensate. Scientific Reports, 4, 1-6. https://doi.org/10.1038/srep06436

We introduce a primary thermometer which measures the temperature of a Bose-Einstein Condensate in the sub-nK regime. We show, using quantum Fisher information, that the precision of our technique improves the state-of-the-art in thermometry in the s...

Systematic analysis of the contributions of stochastic voltage gated channels to neuronal noise (2014)
Journal Article
O'Donnell, C., & van Rossum, M. C. (2014). Systematic analysis of the contributions of stochastic voltage gated channels to neuronal noise. Frontiers in Computational Neuroscience, 8, https://doi.org/10.3389/fncom.2014.00105

Electrical signaling in neurons is mediated by the opening and closing of large numbers of individual ion channels. The ion channels' state transitions are stochastic and introduce fluctuations in the macroscopic current through ion channel populatio...

Unruh-DeWitt detector response along static and circular-geodesic trajectories for Schwarzschild-anti-de Sitter black holes (2014)
Journal Article
Ng, K. K., Hodgkinson, L., Louko, J., Mann, R. B., & Martín-Martínez, E. (2014). Unruh-DeWitt detector response along static and circular-geodesic trajectories for Schwarzschild-anti-de Sitter black holes. Physical Review D - Particles, Fields, Gravitation and Cosmology, 90(6), Article 064003. https://doi.org/10.1103/PhysRevD.90.064003

© 2014 American Physical Society. We present novel methods to numerically address the problem of characterizing the response of particle detectors in curved spacetimes. These methods allow for the integration of the Wightman function, at least in pri...

No-activation theorem for Gaussian nonclassical correlations by Gaussian operations (2014)
Journal Article
Mišta, L., McNulty, D., & Adesso, G. (2014). No-activation theorem for Gaussian nonclassical correlations by Gaussian operations. Physical Review A, 90(2), https://doi.org/10.1103/PhysRevA.90.022328

We study general quantum correlations of continuous variable Gaussian states and their interplay with entanglement. Specifically, we investigate the existence of a quantum protocol activating all nonclassical correlations between the subsystems of an...

Cannabinoid-mediated short-term plasticity in hippocampus (2014)
Journal Article
Zachariou, M., & Thul, R. (2014). Cannabinoid-mediated short-term plasticity in hippocampus. Journal of Computational Neuroscience, 37(3), https://doi.org/10.1007/s10827-014-0518-4

Endocannabinoids modulate both excitatory and inhibitory neurotransmission in hippocampus via activation of pre-synaptic cannabinoid receptors. Here, we present a model for cannabinoid mediated short-term depression of excitation (DSE) based on our r... Read More about Cannabinoid-mediated short-term plasticity in hippocampus.
