Long-range quadrupole electron-phonon interaction from first principles
Jinsoo Park, Jin-Jian Zhou, Vatsal A. Jhalani +2
Lattice vibrations in materials induce perturbations on the electron dynamics in the form of long-range (dipole and quadrupole) and short-range (octopole and higher) potentials. Th…
Piezoelectric Electron-Phonon Interaction from Ab Initio Dynamical Quadrupoles: Impact on Charge Transport in Wurtzite GaN
Vatsal A. Jhalani, Jin-Jian Zhou, Jinsoo Park +2
First-principles calculations of -ph interactions are becoming a pillar of electronic structure theory. However, the current approach is incomplete. The piezoelectric (PE) -p…
Gravitational Wave Formation from the Collapse of Dark Energy Field Configurations
Vishal Jhalani, Ayushi Mishra, Anupam Singh
Dark Energy is the dominant component of the energy density of the universe. In a previous paper, we have shown that the collapse of dark energy fields leads to the formation of Su…
Temporal X-ray Reconstruction using Temporal and Spectral Measurements at LCLS
Florian Christie, Alberto Andrea Lutman, Yuantao Ding +7
Transverse deflecting structures (TDS) are widely used in accelerator physics to measure the longitudinal density of particle bunches. When used in combination with a dispersive se…
Precise Radiative Lifetimes in Bulk Crystals from First Principles: The Case of Wurtzite GaN
Vatsal A. Jhalani, Hsiao-Yi Chen, Maurizia Palummo +1
Gallium nitride (GaN) is a key semiconductor for solid-state lighting, but its radiative processes are not fully understood. Here we show a first-principles approach to accurately…
Ab Initio Calculations of Exciton Radiative Lifetimes in Bulk Crystals, Nanostructures and Molecules
Hsiao-Yi Chen, Vatsal A. Jhalani, Maurizia Palummo +1
Excitons are bound electron-hole pairs that dominate the optical response of semiconductors and insulators, especially in materials where the Coulomb interaction is weakly screened…
