Complex symmetric weighted composition operators on Dirichlet spaces and Hardy spaces in the unit ball
Xiao-He Hu, Zi-Cong Yang, Ze-Hua Zhou
In this paper, we investigate when weighted composition operators acting on Dirichlet spaces are complex symmetric with respect to some special conjug…
Several -series related to Ramanujan's theta functions
Dazhao Tang, Ernest. X. W. Xia
Quite recently, the first author investigated vanishing coefficients of the arithmetic progressions in several -series expansions. In this paper, we further study the signs of c…
Symmetry-breaking supercollisions in Landau-quantized graphene
Florian Wendler, Martin Mittendorff, Jacob C. König-Otto +8
Recent pump-probe experiments performed on graphene in a perpendicular magnetic field have revealed carrier relaxation times ranging from picoseconds to nanoseconds depending on th…
Ultrahard carbon film from epitaxial two-layer graphene
Yang Gao, Tengfei Cao, Filippo Cellini +5
Atomically thin graphene exhibits fascinating mechanical properties, although its hardness and transverse stiffness are inferior to those of diamond. To date, there hasn't been any…
