Group Leader

Andrew Daley
Andrew grew up in Auckland, New Zealand, where he completed his Masters degree in Physics in 2002. He received his PhD from the University of Innsbruck in 2005, working in the group of Peter Zoller, on simulation and manipulation of cold atoms in optical lattices. He held an assistant position at the University of Innsbruck and then a senior scientist position at the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences until December 2010. In January 2011 he began a faculty position at the University of Pittsburgh. In his spare time he enjoys Music (including playing the trumpet and piano), theatre, travelling, and watching and participating in a variety of sports.

Postdoctoral Researchers

Stephan Langer
Office: 209 Allen Hall / e-mail: sml110 [at]
Stephan grew up in Lüdenscheid and studied physics at RWTH Aachen University from which he graduated as Diplom-Physiker in 2009. He then continued his work with Fabian Heidrich-Meisner in the group of Ulrich Schollwöck at LMU Munich from which he got his PhD in 2012. The focus of his research up to now was on transport and real-time dynamics in one-dimensional quantum magnets and ultra-cold atomic gases. In cases of spare time he is looking forward to playing his bass guitar, exploring Pittsburgh by bike and to his first penguins game.

  • Graduate Students

    Anton Buyskikh
    Office: 200 Allen Hall / e-mail: anb158 [at]
    Anton was born and raised in Rybinsk, Yaroslavl region, Russia. Then he moved to St. Petersburg where he studied and graduated from the Polytechnical University and presented a master's thesis "Generation of THz radiation in semiconductor nanowires under femtosecond optical excitations". In his free time he likes active sports and reading.
    Saubhik Sarkar
    Office: 200 Allen Hall / e-mail: sas267 [at]
    Saubhik is from a small town in the eastern part of India. He did his undergrad in Physics at St. Stephen's College, New Delhi and then got his Master's degree (Physics) from IIT Kanpur in 2010. He now works with Andrew Daley at the University of Pittsburgh. In his free and not-so-free times he is involved in world film, music, sports and daydreaming about travelling the world.
    Guanglei Xu
    Office: 200 Allen Hall / e-mail: gux11 [at]
    Guanglei grew up in Shijiazhuang, Hebei, not far from Beijing. He graduated from Shanghai Jiao Tong University, in Shanghai, and moved to Chicago for his master's degree at the Illinois Institute of Technology, 2010. Now he is working with Andrew Daley in Pittsburgh and Rolando Somma at the Los Alamos National Laboratory. In his free time, music is always around him.

    Former Group members

    Johannes Schachenmayer
    PhD 2012, Postdoc 2013, now a Postdoctoral Fellow at JILA, Boulder, Colorado
    Johannes grew up in Zwiesel, a small town in Bavaria, Germany. He studied Physics at the Technical University in Munich and graduated as "Diplom-Physiker" in 2008. In his diploma-thesis he worked on "Dynamics and Long-Range Interactions in 1D Quantum Sytems" together with Andrew Daley and Peter Zoller at the University of Innsbruck. He is currrently working on his PhD thesis with Andrew Daley as a visiting scholar at the University of Pittsburgh. When he has no free time he misses paragliding, travelling or playing the piano.
