Welcome to ARPES group at Boston College. It was started by Prof. Hong Ding, who joined the Department of Physics at Boston College in 1998.

    The research area of the group is to study strongly correlated electron systems and low dimensional materials by using the experimental method of Angle-Resloved PhotoEmission Spectroscopy(ARPES) . ARPES is based on photoelectric effect in which photons incident on a sample cause electrons to be ejected whose intensity is measured as function of momentum and energy. ARPES is an unique experimental tool that is capable of probling momentum resolved physical properties of a solid.

    Our current research activities focus on the high T_c superconductors. ARPES has contributed to the understanding of the high-T_c superconductivity by measuring the electronic band structure, the Fermi Surface, the symmetry of order parameter, the pseudogap, the self energy etc. Some of our contribution can be found un our publications.

    We have a on-campus ARPES facility which is based on a helium discharging lamp. In addition, a portion of our work is done in the Synchrontron Radiation Center in stoughton, Wisconsin.

    Currently there are three members in the group. Prof. Hong Ding, and two Ph.D students Shancai Wang and Hongbo Yang. Several undergraduate students had worked in our group.
