Towards Single Atom Computing via High Harmonic Generation
Gerard McCaul, Kurt Jacobs, Denys I. Bondar
The development of alternative platforms for computing has been a longstanding goal for physics, and represents a particularly pressing concern as conventional transistors approach…
Multiphoton-double-ionization probability linearly depends on laser intensity: Experimental studies of barium
I. I. Bondar, V. V. Suran, D. I. Bondar
Despite inherently complex multiphoton dynamics, our observations show that Ba double ionization with an infrared laser (8800-8920 cm^{-1}) resembles a single-photon process; namel…
Applications of Adiabatic Approximation to One- and Two-electron Phenomena in Strong Laser Fields
Denys Bondar
The adiabatic approximation is a natural approach for the description of phenomena induced by low frequency laser radiation because the ratio of the laser frequency to the characte…
Shapes of leading tunnelling trajectories for single-electron molecular ionization
Denys I. Bondar, Wing-Ki Liu
Based on the geometrical approach to tunnelling by P.D. Hislop and I.M. Sigal [Memoir. AMS 78, No. 399 (1989)], we introduce the concept of a leading tunnelling trajectory. It is t…
Non-sequential double ionization below laser-intensity threshold: Anticorrelation of electrons without excitation of parent ion
D. I. Bondar, G. L. Yudin, W. -K. Liu +2
Two-electron correlated spectra of non-sequential double ionization below laser-intensity threshold are known to exhibit back-to-back scattering of the electrons, viz., the anticor…
An electron in the presence of multiple zero range potentials and an external laser field -- exact solutions for photoionization and stimulated bremsstrahlung
Denys I. Bondar, Ryan Murray, Misha Yu. Ivanov
The method of zero range potential (ZRP) for one-electron problems is reviewed. In the absence of an external electromagnetic field, the notion of a ZRP is introduced from differen…
