Phoretic flow induced by asymmetric confinement
(Cambridge University PressJournal of Fluid Mechanics, 2016-06-28)
Internal phoretic flows due to the interactions of solid boundaries with local chemical gradients may be created using chemical patterning. Alternatively, we demonstrate here that internal flows might also be induced by ...
Integrable Abelian vortex-like solitons
(ElsevierPhysics Letters B, 2017-05-10)
We propose a modified version of the Ginzburg–Landau energy functional admitting static solitons and determine all the Painlevé-integrable cases of its Bogomolny equations of a given class of models. Explicit solutions are ...
Near-wall diffusion tensor of an axisymmetric colloidal particle
(AIPJournal of Chemical Physics, 2016-07-20)
Hydrodynamic interactions with confining boundaries often lead to drastic changes in the diffusive behaviour of microparticles in suspensions. For axially symmetric particles, earlier numerical studies have suggested a ...
End Point of the Ultraspinning Instability and Violation of Cosmic Censorship
(American Physical SocietyAmerican Physical SocietyPhysical Review Letters, 2017-04-14)
We determine the end point of the axisymmetric ultraspinning instability of asymptotically flat Myers-Perry black holes in D = 6 spacetime dimensions. In the nonlinear regime, this instability gives rise to a sequence of ...
Worldsheet methods for perturbative quantum field theory
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2015-10-01)
This thesis is divided into two parts. The first part concerns the study of the ambitwistor string and the scattering equations, while the second concerns the interplay of the symmetries of the asymptotic null boundary of ...
Dynamical tides in exoplanetary systems containing hot Jupiters: Confronting theory and observations
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-09-11)
We study the effect of dynamical tides associated with the excitation of gravity waves in an interior radiative region of the central star on orbital evolution in observed systems containing hot Jupiters. We consider ...
In situ accretion of gaseous envelopes on to planetary cores embedded in evolving protoplanetary discs
(Oxford University PressMONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2017-09-21)
The core accretion hypothesis posits that planets with significant gaseous envelopes accreted them from their protoplanetary discs after the formation of rocky/icy cores. Observations indicate that such exoplanets exist ...
Quantum conditional query complexity
(Rinton PressQuantum Information and Computationhttp://www.rintonpress.com/journals/qicabstracts/qicabstracts17-78.html, 2017-06-01)
We define and study a new type of quantum oracle, the quantum conditional oracle, which provides oracle access to the conditional probabilities associated with an underlying distribution. Amongst other properties, we (a) ...
A two-fluid model for locomotion under self-confinement
(American Physical SocietyPhysical Review Fluids, 2017-09-01)
The bacterium Helicobacter pylori causes ulcers in the stomach of humans by invading mucus layers protecting epithelial cells. It does so by chemically changing the rheological properties of the mucus from a high-viscosity ...
A Yellow Polariton Condensate in a Dye Filled Microcavity
(WileyAdvanced Optical Materials, 2017-09-18)
Polariton condensation in the yellow part of the visible spectrum from a planar organic semiconductor microcavity containing the molecular dye bromine-substituted boron-dipyrromethene is observed. This study provides ...
