Title: Observation of quantum interferences via light-induced conical intersections in diatomic molecules

Abstract

We observe energy-dependent angle-resolved diffraction patterns in protons from strong-field dissociation of the molecular hydrogen ion H⁺₂. The interference is a characteristic of dissociation around a laser-induced conical intersection (LICI), which is a point of contact between two surfaces in the dressed 2-dimensional Born-Oppenheimer potential energy landscape of a diatomic molecule in a strong laser field. The interference magnitude and angular period depend strongly on the energy difference between the initial state and the LICI, consistent with coherent diffraction around a cone-shaped potential barrier whose width and thickness depend on the relative energy of the initial state and the cone apex. As a result, these findings are supported by numerical solutions of the time-dependent Schrodinger equation for similar experimental conditions.

Diabolical conical intersections

Journal Article Yarkony, D R - Reviews of Modern Physics

In the Born-Oppenheimer approximation for molecular dynamics as generalized by Born and Huang, nuclei move on multiple potential-energy surfaces corresponding to different electronic states. These surfaces may intersect at a point in the nuclear coordinates with the topology of a double cone. These conical intersections have important consequences for the dynamics. When an adiabatic electronic wave function is transported around a closed loop in nuclear coordinate space that encloses a conical intersection point, it acquires an additional geometric, or Berry, phase. The Schr{umlt o}dinger equation for nuclear motion must be modified accordingly. A conical intersection also permits efficient nonadiabatic transitionsmore »« less

High-order harmonic generation in diatomic molecules: A quantum-orbit analysis of the interference patterns

Journal Article Figueira de Morisson Faria, C. - Physical Review. A

We perform a detailed analysis of high-order harmonic generation in diatomic molecules within the strong-field approximation (SFA), with emphasis on quantum-interference effects. Specifically, we investigate how the different types of electron orbits, involving one or two centers, affect the interference patterns in the spectra. We also briefly address the influence of the choice of gauge and of the initial and final electronic bound states on such patterns. For the length-gauge SFA and undressed bound states, there exist additional terms, which can be interpreted as potential energy shifts. If, on the one hand, such shifts alter the potential barriers through whichmore »« less

Resonant Auger decay of the core-excited C{sup *}O molecule in intense x-ray laser fields

Journal Article Demekhin, Philipp V ; Chiang, Ying-Chih ; Cederbaum, Lorenz S - Physical Review. A

The dynamics of the resonant Auger (RA) process of the core-excited C*O(1s{sup -1}{pi}*,v{sub r}=0) molecule in an intense x-ray laser field is studied theoretically. The theoretical approach includes the analog of the conical intersections of the complex potential energy surfaces of the ground and 'dressed' resonant states due to intense x-ray pulses, taking into account the decay of the resonance and the direct photoionization of the ground state, both populating the same final ionic states coherently, as well as the direct photoionization of the resonance state itself. The light-induced nonadiabatic effect of the analog of the conical intersections of themore »« less

Photochemistry of pyrrole: Time-dependent quantum wave-packet description of the dynamics at the {sup 1}{pi}{sigma}*-S{sub 0} conical intersections

Journal Article Vallet, Valerie ; Lan, Zhenggang ; Mahapatra, Susanta ; ... - Journal of Chemical Physics

The photoinduced hydrogen-elimination reaction in pyrrole via the conical intersections of the two {sup 1}{pi}{sigma}* excited states with the electronic ground states [{sup 1}B{sub 1}({pi}{sigma}*)-S{sub 0} and {sup 1}A{sub 2}({pi}{sigma}*)-S{sub 0}] have been investigated by time-dependent quantum wave-packet calculations. Model potential-energy surfaces of reduced dimensionality have been constructed on the basis of accurate multireference ab initio electronic-structure calculations. For the {sup 1}B{sub 1}-S{sub 0} conical intersection, the model includes the NH stretching coordinate as the tuning mode and the hydrogen out-of-plane bending coordinate as the coupling mode. For the {sup 1}A{sub 2}-S{sub 0} conical intersection, the NH stretching coordinate andmore »« less

We calculate the adiabatic Potential Energy Surfaces (PESs) and the Non-Adiabatic Coupling Terms (NACTs) for the three lowest singlet states of H{sub 3}{sup +} in hyperspherical coordinates as functions of hyperangles (θ and ϕ) for a grid of fixed values of hyperradius (1.5 ⩽ ρ ⩽ 20 bohrs) using the MRCI level of methodology employing ab initio quantum chemistry package (MOLPRO). The NACT between the ground and the first excited state translates along the seams on the θ − ϕ space, i.e., there are six Conical Intersections (CIs) at each θ (60° ⩽ θ ⩽ 90°) within the domain, 0more »« less
