# 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**

__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 pioneering
foundational discoveries in 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.
