Three Dimensional Orientation of Complex Molecules Excited by Two-Color Femtosecond Pulses
Long Xu, Ilia Tutunnikov, Yehiam Prior +1
We study the excitation of asymmetric-top (including chiral) molecules by two-color femtosecond laser pulses. In the cases of non-chiral asymmetric-top molecules excited by an orth…
Long-Lasting Orientation of Symmetric-top Molecules Excited by Two-Color Femtosecond Pulses
Long Xu, Ilia Tutunnikov, Yehiam Prior +1
Impulsive orientation of symmetric-top molecules excited by two-color femtosecond pulses is considered. In addition to the well-known transient orientation appearing immediately af…
Enantioselective Orientation of Chiral Molecules Induced by Terahertz Pulses with Twisted Polarization
Ilia Tutunnikov, Long Xu, Robert W. Field +3
Chirality and chiral molecules are key elements in modern chemical and biochemical industries. Individual addressing, and the eventual separation of chiral enantiomers has been and…
Echoes in Unidirectionally Rotating Molecules
Long Xu, Ilia Tutunnikov, Lianrong Zhou +6
Abstract We report the experimental observation of molecular unidirectional rotation (UDR) echoes, and analyze their origin and behavior both classically and quantum mechanically.…
Long-lasting Molecular Orientation Induced by a Single Terahertz Pulse
Long Xu, Ilia Tutunnikov, Erez Gershnabel +2
Control of molecular rotations by laser fields is an active area of research focusing on the alignment/orientation of otherwise isotropic molecular samples. Oriented molecules are…
Understanding tunneling ionization of atoms in laser fields with the essence of multiphoton absorption
Long Xu, Libin Fu
The elaborate energy and momentum spectra of ionized electrons from atoms in laser fields suggest that the ionization dynamics described by tunneling theory should be modified. Alt…
