Topical Group on Few-Body Systems & Multiparticle Dynamics

Our mission: To advocate, promote, and advance research on few-body systems.

Who we are: The APS Topical Group on Few-Body Systems and Multiparticle Dynamics was formed in January, 1985. We are an umbrella organization of atomic, molecular, nuclear, particle, and mathematical physicists, as well as quantum chemists, who are interested in the dynamics of “simple” systems. Such systems have relatively few degrees of freedom at some energy scale, and their study provides significant information about the dynamics of systems in a given area of physics, as well as identifies features common to systems in a variety of different sub-disciplines. Because we are an interdisciplinary group, many of our sessions at APS meetings are held jointly with other Groups and Divisions and feature specific “themes” from different fields.

What we do:

  • Offer travel grants for students and postdoctoral researchers who are presenting their work at the APS April and DAMOP meetings.
  • Organize and sponsor workshops and conferences (or portions thereof), and work to ensure representation of few-body topics at relevant workshops and conferences.
  • Nominate APS Fellows whose accomplishments are centered around few-body topics.
  • Communicate with and inform GFB members through regular emails and an annual newsletter.

How to join: To join any topical group, American Physical Society (APS) membership is required. All physicists who are APS members and who have an interest in few-body problems are encouraged to sign up for the Topical Group. Those who are not members are encouraged to join APS.

Two APS Fellowships Awarded Through GFB
APS announced the newly elected 2016 APS Fellows. Two fellowships have been awarded through GFB. Our two new fellows are:

  • William Detmold (MIT) - "For pioneering work in calculating few-body hadronic systems from first principles using lattice quantum chromodynamics, including the spectrum of the light nuclei and hypernuclei, Bose-condensed multimeson systems, and the first inelastic nuclear reaction"
  • Kalman Varga (Vanderbilt University) - "For the development of a class of variational methods for accurate treatment of quantum few-body systems of various natures."

Congratulations to William and Kalman!

Faddeev Medal Announcement
GFB and the European Research Committee on Few Body Problems in Physics (ERCFBP) announce a new award to recognize distinguished achievement in Few-Body Physics, the Faddeev medal, named in honor of our outstanding colleague Ludwig Faddeev.
