      The exciton and biexciton confinement regimes in strongly anisotropic epitaxial InAs nanostructures called quantum dashes (QDashes) embedded in an In0.53Ga0.23Al0.24As matrix, which is lattice-matched to InP(001) substrate, ...
    • Editing Cavendish : Maxwell and The Electrical Researches of Henry Cavendish 

      Falconer, Isobel (Living Edition/STARNA, 2017) - Conference item
      During the last five years of his life, 1874-79, James Clerk Maxwell was absorbed in editing the electrical researches of Henry Cavendish, performed 100 years earlier. This endeavour is often assumed to be a work of duty ...
    • Evaluating galactic habitability using high-resolution cosmological simulations of galaxy formation 

      Forgan, Duncan; Dayal, Pratika; Cockell, Charles; Libeskind, Noam (2017-01) - Journal article
      We present the first model that couples high-resolution simulations of the formation of local group galaxies with calculations of the galactic habitable zone (GHZ), a region of space which has sufficient metallicity to ...

      Exciton spin and related optical polarization in self-assembled InAs/In0.53Ga0.23Al0.24As/InP(001) quantum dashes emitting at 1.55 μm are investigated by means of polarization- and time-resolved photoluminescence, as well ...
    • Exoplanet transits as the foundation of an interstellar communications network 

      Forgan, Duncan H. (2018-03-12) - Journal article
      Two fundamental problems for extraterrestrial intelligences (ETIs) attempting to establish interstellar communication are timing and energy consumption. Humanity's study of exoplanets via their transit across the host star ...
    • The Galactic Club or Galactic Cliques? Exploring the limits of interstellar hegemony and the Zoo hypothesis 

      Forgan, Duncan H. (2017-10) - Journal article
      The Zoo solution to Fermi's Paradox proposes that extraterrestrial intelligences (ETIs) have agreed to not contact the Earth. The strength of this solution depends on the ability for ETIs to come to agreement, and ...
    • Hybrid reflections from multiple x-ray scattering in epitaxial oxide films 

      Smith, Eva H.; King, Phil D. C.; Soukiassian, Arsen; Ast, Dieter G.; Schlom, Darrell G. (2017-09-29) - Journal article
      In numerous symmetric θ-2θ scans of phase-pure epitaxial complex oxide thin films grown on single-crystal substrates, we observe x-ray diffraction peaks that correspond to neither the film nor the substrate crystal structure. ...
    • Irreversible magnetization switching at the onset of superconductivity in a superconductor ferromagnet hybrid 

      Curran, P. J.; Kim, J.; Satchell, N.; Witt, J. D. S.; Burnell, G.; Flokstra, M. G.; Lee, S. L.; Cooper, J. F. K.; Kinane, C. J.; Langridge, S.; Isidori, A.; Pugach, N.; Eschrig, M.; Bending, S. J. (2015-12-30) - Journal article
      We demonstrate that the magnetic state of a superconducting spin valve, that is normally controlled with an external magnetic field, can also be manipulated by varying the temperature which increases the functionality and ...
    • Phases of physics in J.D. Forbes’ Dissertation Sixth for the Encyclopaedia Britannica (1856) 

      Falconer, Isobel Jessie (2018-12-03) - Journal article
      This paper takes James David Forbes’ Encyclopaedia Britannica entry, Dissertation Sixth, as a lens to examine physics as a cognitive, practical, and social, enterprise. Forbes wrote this survey of eighteenth- and ...
    • Planetary science and exploration in the deep subsurface : results from the MINAR Program, Boulby Mine, UK 

      Payler, Samuel J.; Biddle, Jennifer F.; Coates, Andrew J.; Cousins, Claire R.; Cross, Rachel E.; Cullen, David C.; Downs, Michael T.; Direito, Susana O.

      The subsurface exploration of other planetary bodies can be used to unravel their geological history and assess their habitability. On Mars in particular, present-day habitable conditions may be restricted to the subsurface. ...
