BIO:

Tim Byrnes completed his PhD at the University of New South Wales in Sydney, Australia in the fields of condensed matter physics and high energy physics under the supervision of Prof. Chris Hamer.  During this time he worked on applications of  DMRG (Density Matrix Renomalization Group), a powerful method for solving 1D quantum many-body problems, to lattice gauge theories.  He then moved to Tokyo, Japan to commence a postdoctoral fellowship with Prof. Yoshihisa Yamamoto in the field of quantum information at the National Institute of Informatics and the University of Tokyo.  There he worked on topics related to quantum simulation, such as methods of solving lattice gauge theories on a quantum computer, and semiconductor implementations of a quantum simulator.  He has worked on the theory of Bose-Einstein condensation in exciton-polariton systems, such as the BEC-BCS crossover and applications to the generation of non-classical light.   He is now Assistant Professor at New York University (Shanghai campus), where he examines Bose-Einstein condensates for various applications in quantum information technology.

Position: Assistant Professor of Physics

CAREER:

July 2014-Present || Rice University, Assistant Professor of Physics and Astronomy

2010-2014 || JILA, NIST, University of Colorado, Boulder

2004-2010 || Laboratory of Atomic and Solid-State Physics, Cornell University

BIO:
Kaden Hazzard studies the behavior of ultracold atomic systems with a mix of analytical and computational methods. He is interested in "emergent" properties of many-body systems, and spend most of his time thinking about this phenomenon in ultracold gases. The vision is that fundamental advances in controlling, measuring, and understanding these many-body quantum systems will impact our knowledge of other fields through "quantum simulation", broadly construed, and enable applications in quantum metrology, precision measurement, and quantum computation. Dr Hazzard grew up in Ohio and attended the Ohio State University for his bachelor's degree. He received his PhD from Cornell University, working with Erich Mueller in 2010. He spent 2010-14 as a postdoc at JILA working with Ana Maria Rey and collaborating with lots of other JILAns. Since July 2014, he has been an Assistant Professor in the Rice University department of physics.
