Dr. R. Caballar

Post Doc Fellow

Dr. Caballar obtained his B.Sc. in Physics-Mathematics from the University of the Philippines-Baguio in October 2001. He immediately left for the University of the Philippines-Diliman, where he obtained his M.Sc. in Physics in April 2005 and his Ph.D. in Physics in October 2009.

For his M.Sc. and Ph.D. work, Dr. Caballar conducted research on the quantum time problem, in particular on multiple solutions to the time-energy canonical commutation relation. He was able to show that for a system described by a particular Hamiltonian, there exists multiple self-adjoint time operators canonically conjugate to this Hamiltonian, with each of these operators having unique physical interpretations which are obtained by analyzing the dynamics of the system.

Wanting to move on to a new research field after his Ph.D., Dr. Caballar went north to South Korea as a postdoctoral researcher in April 2012 to work with Prof. Gentaro Watanabe on dissipative quantum state preparation using ultracold atoms at the Asia-Pacific Center for Theoretical Physics housed in Pohang, Republic of Korea. During his stay, Dr. Caballar also learned much about ultracold atoms and open quantum systems. After his year in Korea was up, he left for South Africa, this time to work with Prof. Francesco Petruccione on open quantum systems at the Centre for Quantum Technology, School of Physics and Chemistry, University of KwaZulu-Natal Westville Campus in Durban.

His current research interests are open quantum systems, ultracold atoms and dissipative quantum state preparation.
