Have some fun(nel) on a tunnel or sun(nel) walk! Join us for a 30-minute volunteer-led walk either through MIT's famous tunnel system or around Killian Court. As the weather gets warmer, walk leaders may choose to take the group outside. Is the weather warm and you missed the start? Find the group on Killian Court and join in!Location details: Meet in the lobby under the “Belonging + Community” banner. Location photo below.Sun(nel) Walk Leaders will identify themselves by holding a white at the meeting location.Prize Drawing: Attend a walk and scan a QR code from the walk leaders to be entered into a drawing for a getfit canvas boat tote bag at the end of the getfit challenge. The more walks you attend, the more entries you get. Winner will be drawn and notified at the end of April. Winner does not need to be a getfit participant.Disclaimer: Tunnel walks are led by volunteers. In the rare occasion when a volunteer isn’t able to make it, we will do our best to notify participants. In the event we are unable to notify participants and a walk leader does not show up, we encourage you to walk as much as you feel comfortable doing so. We recommend you check this calendar just before you head out!Getfit is a 12-week fitness challenge for the entire MIT community. These tunnel walks are open to the entire MIT community and you do not need to be a current getfit participant to join.

Register here.We will be making eclectic Crystal Rhinestone Painting Suncatcher. These decorative suncatcher ornaments will bring a sparkling touch to your interior decor. These Crafternoon events provide for a great opportunity to connect with fellow spouses and partners from MS&PC and create long-lasting memories. Children are welcome to join as well. We will be providing all supplies for this event, sponsored by MS&PC.If you have any questions, please contact Miyuki Ota: miyukichan8@hotmail.com.

Speaker: Denis Bernard (CMSA, Harvard, and Ecole Normale Supérieure de Paris)In person or on Zoom: https://mit.zoom.us/j/92441268505Title: A group theory perspective on quantum exclusion processesAbstract: Exclusion processes are stochastic particle lattice systems modeling fluctuations in classical diffusive systems. Their extensive study over the past decades led to the formulation of the now called macroscopic fluctuation theory - a framework extending Bolztman's theory to non-equilibrium diffusive systems. In the first part of the talk, I will describe the newly proposed quantum extension of exclusion processes, aiming at formulating a quantum version of the macroscopic fluctuation theory. The focus will be on the interplay between group theory and probability theory at play in solving these models. In the second part, I will describe elements of a theory of structured random matrices which has emerged from studying these models.
