With a 65-45 victory over Bowdoin, Amherst women’s basketball completed its second perfect, undefeated season with a record of 33-0. From the last two minutes of the third quarter until the final three minutes of the game, the Mammoths shut out the Polar Bears with organized and efficient defense.

Physics Professor and Students College Remembers Senior Andrew Discover ‘Skyrmion’ Quasiparticle Dorogi After Death on March 16 Kathleen Maeder ’20 Staff Writer Professor of Physics David Hall ’91, working with a team of recent physics graduates, has published a paper about his recent discovery of a three-dimensional skyrmion in an experiment with unusual electromagnetic-like properties. Though trained as an atomic physicist, Hall was drawn to topology, a branch of mathematics that focuses on the continuous deformation of shapes. “Topology is that thing that lets you distinguish shapes from one another, and it involves taking a shape and possibly deforming it in some way,” he said. In order to conduct his studies on quasiparticles, Hall and his team first formed a superfluid by lowering atoms to billionths of a degree below zero, creating a “flow of atoms without any viscosity.” He then studied how quasiparticles introduced to the superfluid behave. Hall’s earlier research discussed how monopoles — “simple point objects,” according to Hall — acted in superfluid. He then worked with knots, which is essentially an extended object — “a twisting that can’t untwist itself,” explained Hall. Hall’s most recent work has focused on skyrmions. His recent publication indicates that “not only is the [skyrmion] knotted, but the electromagnetic field-equivalent is also knotted.” Throughout his topological studies, Hall has collaborated with Aalto University in Finland.

He discussed how, prior to their cooperation on publications, he studied vortex-like particles similar to those that Aalto researchers were working on. “We did this neat vortex experiment… I was working with some theorists at UMass, and we were actually competitors there, at the beginning … and they published their paper first, much to my chagrin,” said Hall. Mikko Möttönen, the principal investigator from the Aalto research team, reached out to offer advice on adjusting their experiment. Over time, the professors from both universities developed a partnership. Two of Hall’s former thesis students, Andrei Horia Gheorghe ’15 and Wonjae Lee ’16, were also involved in the research on the three-dimensional skyrmion. “I was really interested in this project, as we discovered that the spin texture of the skyrmion shows the electromagnetic knot structure, which is analogous to the ball lightning,” Lee said in an email interview. “Ball lightning is a natural phenomenon which hasn’t been explained yet, and we think that studying this skyrmion structure will help us with understanding the ball lightning structure too.” Hall added that his future research will likely focus on the dynamics of these quasiparticles. “The first thing we wanted to do was learn how to make [skyrmion], and the second thing we want to do is then discover what they do,” said Hall. “It may give us a hint into what’s happening in the universe.”

Isabel Tessier ’19 Editor-in-Chief Andrew Dorogi ’18, an economics major and varsity football player from Cleveland, Ohio, died on Friday, March 16. President Biddy Martin announced his death in an email to the college community on Sunday, March 18. “Andrew touched the lives of so many students, faculty, coaches and staff on our campus and his sudden death is a profound blow,” Martin wrote in a second email on Monday. She urged students to take care of themselves and provide comfort and support to others. On Monday night, an open community gathering was held in Cole Assembly Room. The group, a mix of students, coaches and faculty who filled the room to capacity, shared memories of Dorogi and thoughts on how to honor him and comfort to grieving friends. In the middle of the room, a large picture of Dorogi’s senior year roster photo stood surrounded by flowers. Martin began the gathering with a brief speech before opening up the floor for students, staff and faculty to speak. “It’s a long process, the work of mourning the loss of someone who’s loved,” Martin said. “And tonight is just one form of beginning that process.” Many people remembered Dorogi for his friendliness, humor and enthusiasm for life. Friend and fellow teammate Kevin Sheehan

’18 said, “To me, Dorogi was just a guy with a huge heart … He was the kind of guy that would always put a smile on your face, no matter what.” Sheehan shared a memory of Dorogi living in Charles Pratt during his freshman year. “It didn’t matter what he was up to, everybody was in his room,” Sheehan said. “He wanted that though — that’s who he was. He wanted company, and he wanted to make people happy; he wanted to be with everybody.” Associate Dean and Director of the Counseling Center Jackie Alvarez closed the gathering with a reminder to students to seek help and support from the college community. In her earlier email, Martin also encouraged students to use the resources made available by the college in the days following Dorogi’s death. “This is a time for us to reach out to one another and ensure that no one is isolated in their efforts to deal with Andrew’s loss,” Martin wrote. The Counseling Center will be offering open hours for drop-in consultation and small private group sessions on Wednesday, March 21 at 11 a.m., March 26 at 11 a.m., March 27 at 3:30 p.m., March 28 at 1:30 p.m. and March 29 at 11 a.m. Boards to write messages and make cards have been posted outside Chapin Chapel, in the Founders Room in Alumni Gymnasium and in Keefe Campus Center.
