      Localized magnetic fields in arbitrary directions using patterned nanomagnets 

      McNeil, R. P. G.; Schneble, R. J.; Kataoka, M.; Ford, C. J. B.; Kasama, T.; Dunin-Borkowski, R. E.; Feinberg, J. M.; Harrison, R. J.; Barnes, C. H. W.; Tse, D. H. Y.; Trypiniotis, Theodossis; Bland, J. A. C.; Anderson, D.; Jones, G. A. C.; Pepper, M. (2010)
      Control of the local magnetic fields desirable for spintronics and quantum information technology is not well developed. Existing methods produce either moderately small local fields or one field orientation. We present ...

      Novel nonlocal gauge functions in electrodynamics and their effect on quantum mechanical phases 

      Moulopoulos, Konstantinos (2011)
      We point to previously overlooked solutions of the standard gauge transformation equations of Electrodynamics: the generalized "gauge functions" go beyond the usual Dirac phase factors (spatial or temporal integrals of ...

      Spin current depolarization under high electric fields in undoped InGaAs 

      Okamoto, N.; Kurebayashi, H.; Harii, K.; Kajiwara, Y.; Beere, H.; Farrer, I.; Trypiniotis, Theodossis; Ando, K.; Ritchie, D. A.; Barnes, C. H. W.; Saitoh, E. (2011)
      Carrier spin polarization in In0.13Ga0.87 As under high electric fields has been investigated. The spin polarization was created by optical spin orientation techniques and the inverse spin-Hall effect was employed to measure ...

      Tunable excitons in gated graphene systems 

      Djotyan, Anahit P.; Avetisyan, A. A.; Moulopoulos, Konstantinos (SPIE, 2017)
      We develop a microscopic theory of a strong electromagnetic radiation interaction with bilayer graphene where an energy gap is opened by a static electric field perpendicular to graphene planes. We show that an adiabatic ...
