Title: Transport measurements on semimetals in strong magnetic fields

Time: 10:00 - 11:00am, April 19, Sunday
Place: Auditorium room 410, Building 6, HPSTAR (Shanghai)
Host: Bin Chen

Abstract:

Semimetals are fascinating materials with a very small overlap between the conduction band the valence band. Thus, they have no band gap and small carries density of states. Their quantum limit where all carriers are confined into their last Landau levers is achieved with a modest magnetic field. How electrons in those 3D systems would behavior beyond quantum limit under a strong magnetic field is still being studying for long period of time, in view of the intriguing integral and fractional quantum Hall effect in 2D system. In this talk, I will show some new results on graphite and bismuth far beyond their quantum limit. Tentative explanations are also given.


Biography of the Speaker:


Prof. Zengwei Zhu works at Wuhan National High Magnetic Field Center, Huazhong University of Science and Technology. He achieved his Ph.D from Zhejiang University in 2009. His current research is condensed matter physics under extreme conditions such as extreme low temperature and high magnetic field, especially with electric and thermal transport. He published 26 papers, including 2 Nature Physics, 1 PNAS and 1 Phys. Rev. Lett. as the first author.
