Our laboratory fundamentally does not have core time nor imposes specific times for arriving at or leaving the laboratory. However, to monitor research progress and address any sudden issues that students may encounter, we have a weekly individual report session with Nambu sensei on Fridays. Additionally, in our laboratory, seminars are organized during the two main semesters of the academic year, with the participation of all lab members. Furthermore, Japanese students, as well as students from other countries (Vietnam, Malaysia, Indonesia), are very close friends, often going shopping, dining, or just having light chats while enjoying snacks, tea, or coffee.
