Pauli-Lubanski, supertwistors, and the superspinning particle
(Springer NatureJournal of High Energy Physics, 2017-06-28)
We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics. We ...
Rough surface scattering via two-way parabolic integral equation
(EMW PublishingProgress In Electromagnetics Research M, 2017-04-23)
This paper extends the parabolic integral equation method, which is very effective for forward scattering from one-dimensional rough surfaces, to include backscatter. This is done by applying left-right splitting to a ...
Impact of dynamical charm quarks
(Proceedings of ScienceProceedings of Sciencehttps://pos.sissa.it/256/126/, 2017-01-17)
We compute and compare the continuum limits of several quantities in QCD with and without a dynamical charm quark. We consider both low energy quantities, like the hadronic scales r0 and t 0 , and high energy quantities, ...
BPS Approaches to Anyons, Quantum Hall States and Quantum Gravity
(University of CambridgeDAMTP (Mathematics)Trinity College, 2017-10-03)
We study three types of theories, using supersymmetry and ideas from string theory as tools to gain understanding of systems of more general interest.
Firstly, we introduce non-relativistic Chern-Simons-matter field ...
Statistical analysis of neuronal data: Development of quantitative frameworks and application to microelectrode array analysis and cell type classification
(University of CambridgeDAMTPTrinity, 2017-10-01)
With increasing amounts of data being collected in various fields of neuroscience, there is a growing need for robust techniques for the analysis of this information. This thesis focuses on the evaluation and development ...
Spatiotemporal Self-Organization of Fluctuating Bacterial Colonies.
(APSPhysical review letters, 2017-11-03)
We model an enclosed system of bacteria, whose motility-induced phase separation is coupled to slow population
dynamics. Without noise, the system shows both static phase separation and a limit cycle, in which a
rising ...
Mode Selection in Compressible Active Flow Networks.
(Physical review letters, 2017-07-14)
Coherent, large-scale dynamics in many nonequilibrium physical, biological, or information transport networks are driven by small-scale local energy input. Here, we introduce and explore an analytically tractable nonlinear ...
Linear Waves in the Interior of Extremal Black Holes II
(Springer NatureAnnales Henri Poincare, 2017-12-01)
We consider solutions to the linear wave equation in the interior region of extremal Kerr black holes. We show that axisymmetric solutions can be extended continuously beyond the Cauchy horizon and moreover that, if we ...
Does a Growing Static Length Scale Control the Glass Transition?
(Physical review letters, 2017-11-09)
Several theories of the glass transition propose that the structural relaxation time is controlled
by a growing static length scale that is determined by the free energy landscape but not by
the local dynamical rules ...
Inferring condition specific regulatory networks with small sample sizes: a case study in bacillus subtilis and infection of mus musculus by the parasite Toxoplasma gondii
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsDowning College, 2017-10-23)
Modelling interactions between genes and their regulators is fundamental to understanding how, for example a disease progresses, or the impact of inserting a synthetic circuit into a cell. We use an existing method to infer ...
