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…
Quantum mechanics of a free particle from properties of the Dirac delta function
Denys I. Bondar, Robert R. Lompay, Wing-Ki Liu
Based on the assumption that the probability density of finding a free particle is independent of position, we infer the form of the eigenfunction for the free particle, $\bra{x} p…
Enhancement and suppression of tunneling by controlling symmetries of a potential barrier
Denys I. Bondar, Wing-Ki Liu, Misha Yu. Ivanov
We present a class of 2D systems which shows a counterintuitive property that contradicts a semi classical intuition: A 2D quantum particle "prefers" tunneling through a barrier ra…
Adaptation of the Modified Adiabatic Approximation to Strong Field Ionization
Denys I. Bondar, Wing-Ki Liu, Gennady L. Yudin
Savichev's modified adiabatic approximation [Sov. Phys. JETP 73, 803 (1991)] is used to obtain a general form of a quantum-mechanical amplitude of ionization by a low-frequency las…
Photoelectron spectra in strong-field ionization by a high frequency field
Denys I. Bondar, Michael Spanner, Wing-Ki Liu +1
We analyze atomic photoelectron momentum distributions induced by bichromatic and monochromatic laser fields within the strong field approximation (SFA), separable Coulomb-Volkov a…
