Journal Article
Soldatos, K. P. (2018). A complete set of independent and physically meaningful invariants in the mechanics of solids reinforced by two families of fibres. Mechanics Research Communications, 94, (49-52). doi:10.1016/j.mechrescom.2018.09.001. ISSN 0093-6413

It has recently been shown [2, 3] that only seven of the classical deformation invariants employed in hyperelasticity of solids reinforced by two families of unidirectional fibres are independent. This short communication demonstrates a manner in whi...

The total photoionization cross section of planar helium has been calculated up to the single ionization threshold I22 of triple P states. The cross section shows chaotic fluctuations as the energy E approaches the double ionization threshold E=0. By...

Individual preventive social distancing during an epidemic may have negative population-level outcomes (2018)
Journal Article
Leung, K. Y., Ball, F., Sirl, D., & Britton, T. (2018). Individual preventive social distancing during an epidemic may have negative population-level outcomes. Interface, 15, doi:10.1098/rsif.2018.0296. ISSN 1742-5662

The outbreak of an infectious disease in a human population can lead to individuals responding with preventive measures in an attempt to avoid getting infected. This leads to changes in contact patterns. However, as we show in this paper, rational be...

Probabilistic distillation of quantum coherence (2018)

The ability to distill quantum coherence is pivotal for optimizing the performance of quantum technologies; however, such a task cannot always be accomplished with certainty. Here we develop a general framework of probabilistic distillation of quantu... Read More about Probabilistic distillation of quantum coherence.

Scattering approach to Anderson localization (2018)

We develop a novel approach to the Anderson localization problem in a d-dimensional disordered sample of dimension L×Md−1. Attaching a perfect lead with the cross section Md−1 to one side of the sample, we derive evolution equations for the scatterin... Read More about Scattering approach to Anderson localization.

Noisy frequency estimation with noisy probes (2018)
Journal Article

We consider frequency estimation in a noisy environment with noisy probes. This builds on previous studies, most of which assume that the initial probe state is pure, while the encoding process is noisy, or that the initial probe state is mixed, whil...

Quantum propagation across cosmological singularities (2017)

The initial singularity is the most troubling feature of the standard cosmology, which quantum effects are hoped to resolve. In this paper, we study quantum cosmology with conformal (Weyl) invariant matter. We show that it is natural to extend the sc...

Journal Article
Gielen, S. (2015). Identifying cosmological perturbations in group field theory condensates. Journal of High Energy Physics, 2015(8), doi:10.1007/jhep08(2015)010

One proposal for deriving effective cosmological models from theories of quantum gravity is to view the former as a mean-field (hydrodynamic) description of the latter, which describes a universe formed by a ‘condensate’ of quanta of geometry. This i... Read More about Identifying cosmological perturbations in group field theory condensates.
