# Participant Donations to
the Center

The Aspen Center for
Physics is an independent non-profit
institution. Its continued existence and
vitality of its programs are ensured by
the generous financial contributions made
by current and past participants, who
appreciate at first hand the value of its
programs. In addition to one-time or
annual donations to the Reserve Fund or
for specific purposes, the Center
specifically recognizes donations by award
winners through the Bethe Circle, and
encourages legacy giving. More information
about recent donations and about how to
donate is given below.

## **BETHE CIRCLE**

** **
Hans Bethe, who was a
long-time Aspen Center for Physics
participant, donated part of the prize
money from his 1967 Nobel Prize in Physics
to the Center for a building, now named
Bethe Hall. Following in Bethe's
footsteps, a number of participants whose
outstanding work has been recognized by
professional awards and prizes have chosen
to donate part or all of the prize money
to support the Center. If you have
received a professional award or prize and
would like to become a member of the Bethe
Circle, contact the Administrative Vice
President by email at acp@aspenphys.org or
by phone at (970) 925-2585.

### **Members of the Bethe Circle**

__Gordon Baym,
University of Illinois Urbana
Champaign__ **2021** **APS
Medal**** for Exceptional Achievement
in Research **[Recognizes
contributions of the highest level that
advance our knowledge and understanding of
the physical universe and in all its
facets. It is intended to celebrate
scientific inquiry and the pursuit of
knowledge.] Chosen for major
discoveries in theoretical condensed
matter and many-body physics, neutron star
structure and composition, quark matter
and quark-gluon plasma physics, and in
atomic physics and ultracold quantum
gases.

__Daniel Freedman,
Stanford University__ **2019 ****Special
Breakthrough Prize**** **[Recognizes
individuals who have made profound
contributions to human knowledge.] Chosen
for the invention of supergravity, in
which quantum variables are part of the
description of the geometry of spacetime.

__ Vassiliki Kalogera, Northwestern
University__ **2016** **Hans A.
Bethe Prize **[Recognizes outstanding
work in theory, experiment or observation
in the areas of astrophysics, nuclear
physics, nuclear astrophysics, or closely
related fields.] Chosen for key
contributions to the study of the
electromagnetic and gravitational wave
radiation from binary compact objects,
including the now–verified prediction that
neutron star mergers produce short
gamma–ray bursts that will be found in all
galaxy types.

__Greg Moore, Rutgers__ **2014
****Dannie Heineman Prize for
Mathematical Physics** [Annual APS
prize since 1959 recognizing outstanding
publications in the field of mathematical
physics.] Chosen for eminent contributions
to mathematical physics with a wide
influence in many fields, ranging from
string theory to supersymmetric gauge
theory, conformal field theory, condensed
matter physics, and four–manifold theory.

__Hirosi Ooguri, Caltech
and Kavli IPMU__** ****2018
Hamburg Prize for Theoretical Physics **[Annual
prize presented by the University of
Hamburg and the Joachim Herz Foundation
for outstanding research achievements in
theoretical physics. This is the first
year the prize covers all areas of
theoretical physics.] Chosen for his
outstanding contributions to the
topological string theory.

__Pierre Ramond, University
of Florida__ **2015** **Dannie
Heineman Prize for Mathematical Physics**
[Annual APS prize since 1959 recognizing
outstanding publications in the field of
mathematical physics.] Chosen for

supersymmetry and superstring theory, in
particular the dual model of fermions and
the theory of the Kalb-Ramond field.

__John Schwarz, Caltech__**
2013 Physics Frontiers Prize**
[Awarded annually by the Fundamental
Physics Prize Foundation, established in
2012 to recognize groundbreaking work in
the field.] Chosen for work developing
superstring theory in collaboration with
Michael Green between 1979 and 1986.

__Matthias Troyer, Microsoft__** 2016
Aneesur Rahman Prize for Computational
Physics **[Annual APS prize
recognizing outstanding achievement in
computational physics research.] Chosen
for pioneering numerical work in many
seemingly intractable areas of quantum
many body physics and for providing
efficient sophisticated computer codes to
the community.
