Since last year new members have joined group E (the publicly offered research group) of the ExU collaboration. We will start an online "ExU interdisciplinary seminar series", inviting mainly the group E members as lecturers. The 1st ExU interdisciplinary seminar will be held on Feb. 22 (Wed) from 10:00 am, with Prof. Kotaro Tamaoka (Nihon U.) and Prof. Tokiro Numasawa (Inst. for Solid State Physics) as lecturers.
