Freezing colloidal suspensions: periodic ice lenses and compaction
(CUP, 2014-10-14)
Recent directional solidification experiments with aqueous suspensions of alumina particles (Anderson & Worster 2012) motivate a model for freezing colloidal suspensions that builds upon a theoretical framework developed ...
Cleaning of Viscous Droplets on an Inclined Planar Surface Using Film Flows
(Australian Fluids Mechanics SocietyProceedings of the Nineteenth Australasian Fluid Mechanics Conference, 2014)
We investigate the fluid mechanics of cleaning viscous drops
attached to a flat inclined surface using thin gravity-driven film
flows. We focus on the case where the drop cannot be detached
from the surface by the mechanical ...
Modelling of partially-resolved oceanic symmetric instability
(ElsevierOcean Modelling, 2014-08-04)
A series of idealized numerical models have been developed to investigate the effects of partially resolved
symmetric instability (SI) in oceanic general circulation models. An analysis of the energetics of symmetric
instability ...
Birational geometry of hypersurfaces in products of projective spaces
(SpringerMathematische Zeitschrift, 2015)
We study the birational properties of hypersurfaces in products of projective spaces. In the case of hypersurfaces in Pm x Pn, we describe their nef, movable and e ective cones and determine when they are Mori dream ...
Post-inflationary non-Gaussianities on the cosmic microwave background
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity Hall, 2015-06-30)
The cosmic microwave background (CMB) provides unprecedented details about the history of our universe and helps to establish the standard model in modern cosmology. With the ongoing and future CMB observations, higher ...
Self-organisation of confined active matter
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2015-06-09)
Active matter theory studies the collective behaviour of self-propelled organisms or objects. Although the field has made great progress in the past decade, little is known of the role played by confinement and surfaces. ...
Complexity Classification of Local Hamiltonian Problems
(IEEEIEEE Symposium on Foundations of Computer Science, 2015-10-22)
The calculation of ground-state energies of physical systems can be formalised as the k-local Hamiltonian problem, which is the natural quantum analogue of classical constraint satisfaction problems. One way of making the ...
Unbounded number of channel uses may be required to detect quantum capacity
(NPGNature Communications, 2015-03-31)
Transmitting data reliably over noisy communication channels is one of the most important applications of information theory, and is well understood for channels modelled by classical physics. However, when quantum effects ...
Stability of local quantum dissipative systems
(SpringerCommunications in Mathematical Physics, 2015-04-07)
Open quantum systems weakly coupled to the environment are modeled
by completely positive, trace preserving semigroups of linear maps. The
generators of such evolutions are called Lindbladians. In the setting of ...
The relationship between a strip Wiener--Hopf problem and a line Riemann--Hilbert problem
(OUPIMA Journal of Applied Mathematics, 2015-03-31)
In this paper, the Wiener–Hopf factorization problem is presented in a unified framework with the
Riemann–Hilbert factorization. This allows to establish the exact relationship between the two types
of factorization. In ...
