Our group focuses on unveiling lots of mysteries surrounding astrophysical explosive phenomena such as supernovae (SNe) and gamma-ray bursts (GRBs). SNe and GRBs are the most powerful explosions in the universe, yet very little is known about their explosion mechanisms. These astrophysical big bangs fascinate us with their unknown physics and puzzling astronomical phenomena such as gravitational waves, neutrinos, nucleosynthesis, non-equilibrium ionization, ultra-high-energy cosmic rays. Through our theoretical and computational approaches, we strive to reveal the complete pictures of these explosions and provide the-state-of-the-art physical interpretations for current, cutting-edge observations and useful predictions for future observations by next-generation astronomical observatories.

In Quantum Dynamics Unit we study a unique system of elementary quantum particles, electrons, floating on the surface of liquid helium. Helium, which is a noble gas at room temperature, becomes liquid when it is cooled down in a refrigerator. Unlike any other substances encountered in nature, helium remains liquid even at the absolute zero temperature, thus contains no impurities and presents the cleanest substrate for electrons. At such low temperatures, electrons behave as quantum objects with charge and spin degrees of freedom, which can be harnessed for interesting applications, such as quantum computing. In Quantum Dynamics Unit we use a variety of experimental techniques such as microwave engineering and microfabrication to study properties of electrons on helium and harness them for quantum technology.
