  • Missing Rung Problem in Vibrational Ladder Climbing
    Missing Rung Problem in Vibrational Ladder Climbing Takahiro Horiba, Soichi Shirai, and Hirotoshi Hirai∗ Toyota Central Research and Development Labs., Inc., 41-1, Yokomichi, Nagakute, Aichi 480-1192, Japan (Dated: August 18, 2021) We observed vanishing of the transition dipole moment, interrupting vibrational ladder climbing (VLC) in molecular systems. We clarified the mechanism of this phenomenon and present a method to use an additional chirped pulse to preserve the VLC. To show the effectiveness of our method, we conducted wavepacket dynamics simulations for LiH dissociations with chirped pulses. The results indicate that the efficiency of LiH dissociation is significantly improved by our method compared to conventional methods. We also revealed the quantum interference effect behind the excitation process of VLC. Controlling molecular reactions as desired is one of such as plasma systems [21] and superconducting circuits the ultimate goals of chemistry. Compared to conven- [22].

Here, we discover the reverse process, symmetry restoration, by means of two circularly polarized laser pulses. The laser pulse for symmetry restoration is designed as a copy of the pulse for symmetry breaking. Symmetry restoration is achieved if the time delay is chosen such that the superposed states have the same phases at the temporal center. This condition must be satisfied with a precision of a few attoseconds. Numerical simulations are presented for 87 the C6H6 molecule and Rb atom. The experimental feasibility of symmetry restoration is demonstrated by means of high-contrast time-dependent Ramsey interferometry of the 87Rb atom. DOI: 10.1103/PhysRevLett.121.173201 The purpose of this Letter is to show that well-designed system is in a quasi-field-free environment—at initial laser pulses can not only break (see, e.g., Refs.

  • A Message from the Chair, Robin Hochstrasser
    DCP News Fall 2005 Division of Chemical Physics The American Physical Society A Message from the Chair The American Physical Society’s Division of Chemical Physics (DCP) is an organizational capability for the broad discipline of chemical physics. Chemical Physics as a named activity goes back to the founding of the Journal by Harold Urey and his colleagues in 1933, and is one of the broadest and most active areas of research in contemporary physics, chemistry, biochemistry, materials science, and …. The time scales of interest in chemical physics run over 20 orders of magnitude, the length scales over at least 12 orders of magnitude. The field has a remarkable richness of methodology, areas of interest, applications, interpretation, and understanding. Given this scope, the Division tries to focus its overall attention, and not to require too much time of its members. We try to keep this newsletter short, and to focus on defining issues for the field, on helping to develop the human capital in the field, and on running the best possible scientific meetings. DCP is undertaking a few new initiatives, including an attempt to work with APS to streamline the organization of the March meeting (and perhaps even allow time for lunch), an extension of the Graduate Student Travel Awards to support more diversity within the program, the stabilization of the Prizes awarded by the APS through the Division (Broida, Langmuir, Plyler). The March meeting this year will be held in Baltimore, and Hai-Lung Dai has assembled a fantastic program. It will be a week of challenging, satisfying science and I urge members both to attend, and if possible to bring young associates — the excitement and depth of the science will be very rewarding for all of us.

IMS is one of the world’s core research facilities for molecular science and is a center for inter-university joint research in Japan, as well. It sets an extremely wide range of research goals, from understanding the behavior of individual molecules to that of collective molecular processes on the scale of life forms and in space. Currently, the IMS is engaged in four areas of research: Theoretical and computational molecular science, photo-molecular science, materials molecular science and life and coordination-complex molecular science. It operates seven research facilities, including the UVSOR Facility. The staff at IMS are making steady progress in basic research on molecular structures, reactions and functions demonstrating “novel molecular capabilities,” as reported in this Review. In addition to these individual research activities,
