Ultrapure Multilayer Graphene in Bromine Intercalated Graphite
J. Hwang, J. P. Carbotte, S. Tongay +2
We investigate the optical properties of bromine intercalated highly orientated pyrolytic graphite (Br-HOPG) and provide a novel interpretation of the data. We observe new absorpti…
Supermetallic conductivity in bromine-intercalated graphite
S. Tongay, J. Hwang, D. B. Tanner +3
Exposure of highly oriented pyrolytic graphite to bromine vapor gives rise to in-plane charge conductivities which increase monotonically with intercalation time toward values (for…
Classical evolution and quantum generation in generalized gravity theories including string corrections and tachyon: Unified analyses
J. Hwang, H. Noh
We present cosmological perturbation theory based on generalized gravity theories including string theory correction terms and a tachyonic complication. The classical evolution as…
Second order perturbations of a zero-pressure cosmological medium: Proofs of the relativistic-Newtonian correspondence
J. Hwang, H. Noh
The dynamic world model and its linear perturbations were first studied in Einstein's gravity. In the system without pressure the relativistic equations coincide exactly with the l…
COBE-DMR constraints on a inflation model with non-minimal scalar field
J. Hwang, H. Noh
We derive the power spectra of the scalar- and tensor-type structures generated in a chaotic-type inflation model based on non-minimally coupled scalar field with a self interactio…
Relativistic cosmological hydrodynamics
J. Hwang, H. Noh
We investigate the relativistic cosmological hydrodynamic perturbations. We present the general large scale solutions of the perturbation variables valid for the general sign of th…
