Variational Polaron Equations Applied to the Anisotropic Fröhlich Model
Vasilii Vasilchenko, Andriy Zhugayevych, Xavier Gonze
Starting from recent advances in the first-principles modeling of polarons, variational polaron equations in the strong-coupling adiabatic approximation are formulated in Bloch spa…
Electronic structure and the glass transition in pnictide and chalcogenide semiconductor alloys. Part II: The intrinsic electronic midgap states
Andriy Zhugayevych, Vassiliy Lubchenko
We propose a structural model that treats in a unified fashion both the atomic motions and electronic excitations in quenched melts of pnictide and chalcogenide semiconductors. In…
Electronic structure and the glass transition in pnictide and chalcogenide semiconductor alloys. Part I: The formation of the -network
Andriy Zhugayevych, Vassiliy Lubchenko
Semiconductor glasses exhibit many unique optical and electronic anomalies. We have put forth a semi-phenomenological scenario (J. Chem. Phys. 132, 044508 (2010)) in which several…
Dynamic correlations in an ordered c(22) lattice gas
P. Argyrakis, M. Maragakis, O. Chumak +1
We obtain the dynamic correlation function of two-dimensional lattice gas with nearest-neighbor repulsion in ordered c(22) phase (antiferromagnetic ordering) under the cond…
Approximate calculation of operator semigroups by perturbation of generators
A. Yurachkivsky, A. Zhugayevych
Let be an operator semigroup with generator in a sequentially complete locally convex topological vector space . For a semigroup with generator , where is a bou…
