Interplay of bulk and interface effects in the electric-field driven transition in magnetite
A. A. Fursina, R. G. S. Sofin, I. V. Shvets +1
Contact effects in devices incorporating strongly-correlated electronic materials are comparatively unexplored. We have investigated the electrically-driven phase transition in mag…
Calculation of model Hamiltonian parameters for LaMnO_3 using maximally localized Wannier functions
Roman Kovacik, Claude Ederer
Maximally localized Wannier functions (MLWFs) based on Kohn-Sham band-structures provide a systematic way to construct realistic, materials specific tight-binding models for furthe…
Formal and finite order equivalences
Dmitri Zaitsev
We show that two families of germs of real-analytic subsets in are formally equivalent if and only if they are equivalent of any finite order. We further apply the same tec…
Integrable structures in LGTs near the deconfinement transition
M. Caselle, G. Delfino, P. Giudice +4
In this contribution we review some recent results about the emergence of 2D integrable systems in 3D Lattice Gauge Theories near the deconfinement transition. We focus on some con…
Finite momentum condensation in a pumped microcavity
R. T. Brierley, P. R. Eastham
We calculate the absorption spectra of a semiconductor microcavity into which a non-equilibrium exciton population has been pumped. We predict strong peaks in the spectrum correspo…
Integrability of invariant metrics on the diffeomorphism group of the circle
Adrian Constantin, Boris Kolev
Each H^k Sobolev inner product defines a Hamiltonian vector field X_k on the regular dual of the Lie algebra of the diffeomorphism group of the circle. We show that only X_0 and X_…
