Linear optical response of current-carrying molecular junction: A NEGF-TDDFT approach
Michael Galperin, Sergei Tretiak
We propose a scheme for calculation of linear optical response of current-carrying molecular junctions for the case when electronic tunneling through the junction is much faster th…
Performance of a non-empirical meta-GGA density functional for excitation energies
Jianmin Tao, Sergei Tretiak, Jian-Xin Zhu
It is known that the adiabatic approximation in time-dependent density functional theory usually provides a good description of low-lying excitations of molecules. In the present w…
Tuning impurity states in bilayer graphene
Hari P. Dahal, A. V. Balatsky, Jian-Xin Zhu
We study the impurity states in bilayer graphene in the unitary limit using Green's function method. Unlike in single layer graphene, the presence of impurities at two non-equivale…
Midgap states in corrugated graphene: Ab-initio calculations and effective field theory
T. O. Wehling, A. V. Balatsky, A. M. Tsvelik +2
We investigate the electronic properties of corrugated graphene and show how rippling-induced pseudomagnetic fields alter graphene's low-energy electronic properties by combining f…
Bogoliubov angle and visualization of particle-hole mixture in superconductors
K. Fujita, Ilya Grigorenko, J. Lee +6
Superconducting excitations --Bogoliubov quasiparticles -- are the quantum mechanical mixture of negatively charged electron (-e) and positively charged hole (+e). Depending on the…
Softening of the insulating phase near Tc for the photo-induced insulator-to-metal phase transition in vanadium dioxide
D. J. Hilton, R. P. Prasankumar, S. Fourmaux +6
We use optical-pump terahertz-probe spectroscopy to investigate the near-threshold behavior of the photoinduced insulator-to-metal (IM) transition in vanadium dioxide thin films. U…
