Quantum Electrodynamics of Dicke States: Resonant One-Photon Exchange and Entangled Decay Rate
U. D. Jentschura, C. M. Adhikari
We calculate the one-photon exchange contribution to the interatomic interaction potential between electrically neutral, identical atoms, one of which is assumed to be in an excite…
Temperature-dependent dielectric function of intrinsic silicon: Analytic models and atom-surface potentials
C. Moore, C. M. Adhikari, T. Das +3
The optical properties of monocrystalline, intrinsic silicon are of interest for technological applications as well as fundamental studies of atom-surface interactions. For an enha…
Collective Excitations and Optical Response of Ultrathin Carbon Nanotube Films
Igor V. Bondarev, Chandra M. Adhikari
We present a theoretical study of the collective quasiparticle excitations responsible for the electromagnetic response of ultrathin plane-parallel homogeneous periodic single-wall…
Controlled Exciton-Plasmon Coupling in a Mixture of Ultrathin Periodically Aligned Single-Wall Carbon Nanotube Arrays
C. M. Adhikari, I. V. Bondarev
We study theoretically the in-plane electromagnetic response and the exciton-plasmon interactions for an experimentally feasible carbon nanotube (CN) film systems composed of paral…
Pressure Shifts in High-Precision Hydrogen Spectroscopy: I. Long-Range Atom-Atom and Atom-Molecule Interactions
U. D. Jentschura, C. M. Adhikari, R. Dawes +2
We study the theoretical foundations for the pressure shifts in high-precision atomic beam spectrosopy of hydrogen, with a particular emphasis on transitions involving higher excit…
Pressure Shifts in High-Precision Hydrogen Spectroscopy: II. Impact Approximation and Monte-Carlo Simulations
A. Matveev, N. Kolachevsky, C. M. Adhikari +1
We investigate collisional shifts of spectral lines involving excited hydrogenic states, where van der Waals coefficients have recently been shown to have large numerical values wh…
