One-dimensional Van Hove polaritons
K. B. Arnardottir, O. Kyriienko, M. E. Portnoi +1
We study the light-matter coupling of microcavity photons and an interband transition in a one-dimensional (1D) nanowire. Due to the Van Hove singularity in the density of states,…
Can habitable planets form in clustered environments?
M. de Juan Ovelar, J. M. D. Kruijssen, E. Bressert +3
We present observational evidence of environmental effects on the formation and evolution of planetary systems. We combine catalogues of resolved protoplanetary discs (PPDs) and yo…
The mode of host-parasite interaction shapes coevolutionary dynamics and the fate of host cooperation
Benjamin J. Z. Quigley, Diana García López, Angus Buckling +2
Antagonistic coevolution between hosts and parasites can have a major impact on host population structures, and hence on the evolution of social traits. Using stochastic modelling…
Nilpotent and abelian Hopf-Galois structures on field extensions
Nigel P. Byott
Let be a finite Galois extension of fields with group . When is nilpotent, we show that the problem of enumerating all nilpotent Hopf-Galois structures on can be…
Radiation hydrodynamics simulations of massive star formation using Monte Carlo radiation transfer
Tim J. Harries, Tom J. Haworth, David Acreman
We present a radiation hydrodynamics simulation of the formation of a massive star using a Monte Carlo treatment for the radiation field. We find that strong, high speed bipolar ca…
Dirac-like plasmons in honeycomb lattices of metallic nanoparticles
Guillaume Weick, Claire Woollacott, William L. Barnes +2
We consider a two-dimensional honeycomb lattice of metallic nanoparticles, each supporting a localized surface plasmon, and study the quantum properties of the collective plasmons…
