Superfluidity of dipolar excitons in a double layer of with a mass term
Oleg L. Berman, Godfrey Gumbs, Gabriel P. Martins +1
We predict Bose-Einstein condensation and superfluidity of dipolar excitons, formed by electron-hole pairs in spatially separated gapped hexagonal (GHAT3) layers. In the…
Dynamical optical conductivity for gapped materials with a curved "flat" band
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +1
We have calculated the dynamical optical conductivity for materials in the presence of a finite bandgap in their energy bandstructure. This is a special type of e…
Glyme-based electrolytes: suitable solutions for next-generation lithium batteries
Daniele Di Lecce, Vittorio Marangon, Hun-Gi Jung +3
The concept of green in a battery involves the chemical nature of electrodes and electrolytes as well as the economic sustainability of the cell. Although these aspects are typical…
Finite-temperature plasmons, damping and collective behavior for model
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +3
We have conducted a thorough theoretical and numerical investigation of the electronic susceptibility, polarizability, plasmons, their damping rates, as well as the static screenin…
Lattice thermal conductivity of pristine and doped (B,N) Graphene
Sarita Mann, Isha Mudahar, Hitesh Sharma +4
In this paper, the effect of B and N doping on the phonon induced thermal conductivity of graphene has been investigated. This study is important when one has to evaluate the usefu…
Geometry-diversified Coulomb excitations in trilayer AAB stacking graphene
Chiun-Yan Lin, Bor-Luen Huang, Godfrey Gumbs +1
The lower-symmetry trilayer AAB-stacked graphene exhibits rich electronic properties and thus diverse Coulomb excitations. Three pairs of unusual valence and conduction bands creat…
