IUPAP Young Scientist Prize in Atomic, Molecular and Optical Physics 2017

Dr. Johannes Feist
Condensed Matter Physics Center (IFIMAC),
Universidad Autónoma de Madrid, Spain

‘For his outstanding contributions in modifications of molecular structure under strong light-matter coupling’.

Johannes Feist received his Ph.D. from Vienna University of Technology in 2009 and afterwards was awarded the ITAMP postdoctoral fellowship at the Institute for Theoretical Atomic, Molecular and Optical Physics (ITAMP) at the Harvard-Smithsonian Center for Astrophysics and Harvard University. In 2012 Johannes joined to the group of F. J. García Vidal as a senior postdoc at the Department of Theoretical Condensed Matter Physics at the Universidad Autónoma de Madrid, and in 2017, he started a tenure-track position as an IFIMAC Young Researcher at the Condensed Matter Physics Center (IFIMAC) in the same university.

His current research focuses on the influence of strong light-matter coupling on the properties of organic materials. In this regime, the interaction between transitions in emitters and confined light modes becomes strong enough that the elemental excitations of the system become hybridized light-matter states, so-called polaritons. This can lead to changes in material properties and even significantly modify chemical reactions. Johannes has made a number of significant contributions to this rapidly growing field, and in particular developed a theory combining molecular physics with cavity QED that can treat polaritonic chemistry by extending the concept of molecular potential energy surfaces to the strong-coupling regime. Based on this work, he has been able to show that nuclear motion in separate molecules could become correlated through their common interaction to a single light mode, as well as that photochemical reactions can be significantly suppressed or novel reaction channels opened under strong light-matter coupling with organic molecules.

Yu-Ao Chen received his Master’s degree from the University of Science and Technology of China (USTC) at Hefei (China) in 2004, and his doctorate from Heidelberg University (Germany) in 2008 under supervision of Prof. Jian-Wei Pan. After spending several years as postdoctoral researcher and project leader working with Prof. Immanuel Bloch in Germany, he returned back to USTC at Shanghai (China) as professor to start up his own group in 2011.

He covers a wide range of the field of AMO physics. He has carried out numerous outstanding achievements, namely multi-photon entanglement in quantum information processing, quantum memory toward long distance quantum communication, and recent works on quantum simulation with ultra-cold atoms in optical lattices.

He has been already awarded many prestigious prizes including the 2013 Fresnel Prize for fundamental aspects from the European Physical Society and the Qiu Shi Outstanding Youth Scholar in China.

The 2015 IUPAP Young Scientist prize for the Commission on Atomic, Molecular and Optical Physics (C15) was awarded Dr Gretchen Campbell.  It was presented at the conference ICPEAC held in 22-28 July 2015.

Gretchen K. Campbell, PhD

The 2015 IUPAP Young Scientist prize for the Commission on Atomic, Molecular and Optical Physics (C15) was awarded Dr Gretchen K Campbell, a Fellow, Joint Quantum Institute, National Institute of Standards and Technology and University of Maryland, Gaithersburg, MD. US,  for her outstanding contributions in toroidal Bose-Einstein condensates and its application to “atomtronic” circuits.

Gretchen K Campbell

She received her Ph.D. in Physics (87Rb Bose-Einstein Condensates in Optical Lattices) in 2007 from MIT, Boston under supervision of W. Ketterle and D. Pritchard. After a postdoc position at Prof. Jun Ye’s group at JILA/NIST, Boulder, she moved to JQI, NIST/Univ. of Maryland as a group leader of the Laser Cooling and Trapping group.

When BEC is held in a toroidal trap, one has quantized circulation around the ring, and the topology prevents the decay of the circulation. Such a system is the “atomtronic” atomic gas analog of a superconducting circuit or a liquid helium superfluid circuit. Campbell pioneered the study of ring-shaped Bose condensates of atomic gases and created the first closed-circuit atomtronic devices. She performed the ground-breaking experiments that incorporated a “circuit element” (a weak-link) into a closed loop of condensate.

 

After this milestone experiments, enormous progresses in this new research field have been achieved by her. For example, she created a design to make the weak link rotate around the ring, where the rotation rate is proportional to an applied magnetic field in the analog electrical circuit, which is essentially an rf SQUID. She found the crucial hysteretic effect in the changing of the circulation state. She also demonstrated that the circulating ring condensate interferes with a static reference condensate. This leads to interferometric measurement of the circulation state like the number of quantized circulations, the direction of circulation, and further the current-phase relationship of the weak-link.

The similarities and differences between Campbell’s atomtronic circuits and the equivalent electric circuits are thus bringing new insights into superfluidity and the controversial nature of critical velocities and the mechanisms for dissipation.
