GFB Travel Awards

Application Deadline: January 31, 2025

The GFB travel award application deadline for the “Global Physics Summit” and “DAMOP Meeting 2025” is Friday, January 31, 2025.

2024 Winner:

Nikolay Yegovtsev is from Almaty, Kazakhstan. He graduated from Nazarbayev University and joined CU Boulder for his graduate studies in 2017. At CU he primarily worked on the Bose polaron problem, a quantum impurity immersed in a three-dimensional Bose-Einstein condensate (BEC). His research was focused on the regime of strong boson-impurity interactions, where the scattering length in the boson-impurity potential can become arbitrarily large. The main result of his work was that although the presence of a single impurity can significantly affect the density of the condensate in its vicinity so that the conventional analytical approaches based on the assumption of uniform condensate fail, the problem nevertheless is analytically tractable for the case of heavy impurity and low gas density. In this regime, the quasiparticle properties of the polaron such as its energy and the number of trapped particles in its cloud are given by universal expansions in terms of an emergent length-scale parameter that comes from the procedure similar to the one used to obtain the s-wave scattering length for a short-ranged potential but requiring to solve the nonlinear Schrödinger equation instead. Nikolay graduated from CU in 2024 and is currently a postdoc at the University of Pittsburgh working on the physics of cold atoms in optical lattices.

Faddeev Medal

Henryk Witała wins Faddeev Medal

The Faddeev Medal was inaugurated in 2016 by the Topical Group on Few-Body Systems & Multiparticle Dynamics (GFB) of the American Physical Society and the European Research Committee on Few-Body Problems in Physics (ERCFBP) to recognize distinguished achievement in Few-Body Physics. It is co-sponsored by the journal Few-Body Systems, published by Springer. The medal, named in honor of distinguished theoretical physicist Ludwig Faddeev (1934-2017), is awarded every three years to a scientist or scientists who advanced the field of Few-Body Physics significantly—either through ground-breaking research or due to crucial progress achieved over the course of a career. The Faddeev Prize is supported by contributions from Springer and the GFB.

An international panel of experts, chaired by Prof. Kimiko Sekiguchi (Tokyo Institute of Technology), has selected the recipient of the 2024 medal:

Henryk Witała "For the life-time achievements in few-nucleon physics, especially for solving the continuum Faddeev equations with realistic nuclear forces and comprehensive studies of three-nucleon dynamics”

The GFB and the ERCFBP wholeheartedly congratulate Prof. Witała. The prize consists of $2500 US, a medal, and an invitation to the 23rd International Conference on Few-body Problems in Physics (FB23) which will be held in 2024 in Beijing, China. Prof. Witała will receive his medal and give a lecture during a special session at the meeting; its text will be published by the journal Few-Body Systems.

Evgeny Epelbaum wins 2021 Faddeev Medal

The Faddeev Medal was inaugurated in 2016 by the Topical Group on Few-Body Systems & Multiparticle Dynamics (GFB) of the American Physical Society and the European Research Committee on Few-Body Problems in Physics (ERCFBP) to recognize distinguished achievement in Few-Body Physics. It is co-sponsored by the journal Few-Body Systems, published by Springer. The medal, named in honor of distinguished theoretical physicist Ludvig Faddeev (1934-2017), is awarded every three years to a scientist or scientists who advanced the field of Few-Body Physics significantly—either through ground-breaking research or due to crucial progress achieved over the course of a career.

An international panel of experts, chaired by Prof. Doerte Blume (U. of Oklahoma, USA), has selected the recipient of the 2021 medal:

Evgeny Epelbaum (Ruhr Universität Bochum, Germany) “For his groundbreaking work on developing high-precision chiral two- and three-nucleon forces that transformed few- and many-body nuclear physics.”

The prize consists of US$2500, a medal, and an invitation to the 23rd International Conference on Few-body Problems in Physics (FB23) which will be held (COVID permitting) in Summer 2022 in Beijing, China. Prof. Epelbaum will receive his medal and give a lecture during a special session at the meeting; its text will be published by the journal Few-Body Systems.

GFB and the ERCFBP wholeheartedly congratulate Prof. Epelbaum. We also want to express our gratitude to Springer and FB23 for the financial support that made this award possible.
