Dr. Bertrand Halperin Harvard University Theory predicts the existence of some peculiar phases of quantum condensed matter systems that have multiple degrees of freedom with very low energy, when localized “defects” are introduced. I shall focus on a class of these phases where each defect has half of a conventional degree of freedom, and the defects may be considered as sites for localized zero-energy states of a “Majorana fermion”. Such defects would also exhibit the intriguing property of “non-Abelian statistics” -- i.e., if various defects can be moved around each other, or if two identical defects can be interchanged, the result is a unitary transformation on the quantum mechanical state that depends on the order in which operations are performed but is insensitive to many other details. In my talk, I will try to explain these various concepts and discuss the attempts to realize them in condensed matter systems.
While STEMCats may be one of the newest Living Learning Communities on campus, it is providing incoming students with many unique opportunities. Students are not only able to live on campus and take courses with like-minded peers, but STEMCats also allows incoming freshmen students to participate in research and connect with peers, upperclassmen, and professors. In this podcast, we talk with several Undergraduate Instructional Assistants, or UIA’s, who have been building connections with STEMCats freshmen through sharing their experiences. Learn more about the STEMCats program and UIA’s as they speak about what they enjoy about the program and their connections with younger students.

Crit Callebs (Eastern Band Cherokee descendant) is a traditional hunter, food gatherer, and fire-tender and lives on the Yakama Nation Indian Reservation. He is completing his Master’s Degree at Central Washington University (CWU) in Cultural Resource Management with an expertise in treaty rights concerning Indian hunting and fishing. He served as the Native American Liaison at the Center for Diversity and Social Justice and was a very popular guest lecturer for the American Indian Studies program. Crit is a trainer for the “Since Time Immemorial” tribal sovereignty and history curriculum implemented in K-12 classrooms in Washington State. As an active member of the Northwest Indian Storytelling Association he has been a featured storyteller for the Tseil-Waututh Nation, CWU Museum of Culture and Environment, Colville Tribes Youth “Warrior Camp” and is the 2014 Alaska Spirit of Reading storyteller. Crit is also a professional survival trainer and former instructor for the world renowned Boulder Outdoors Survival School. One of his great passions is teaching youth and adults how to be self-reliant in the wilderness. Using his gift of storytelling, he travels throughout the U.S. and Canada sharing traditional stories, teaching cultural camps and conducting workshops that promote self-awareness, ancestral skills, and Indigenous values.
The College of Arts and Sciences inducted six new members into its Hall of Fame Oct. 10, 2014, with a ceremony at the Singletary Center for the Arts, bringing the current totals to 38 alumni and 13 emeritus faculty A&S Hall of Fame members.
Dr. Jennifer Francis Rutgers University In this presentation, I will discuss the hypothesis proposed by Francis and Vavrus (2012) that links rapid Arctic warming (so-called Arctic amplification) to changes in the large-scale atmospheric circulation in the northern hemisphere that favors more persistent weather patterns and a higher likelihood of extreme weather events such as droughts, cold spells, flooding, heavy snows, and heat waves. This hypothesis has been a topic of considerable controversy in recent months, particularly regarding its relationship to the unusual weather conditions that persisted in the winter of 2013/2014. I will discuss various aspects of this linkage, what we know and don't know, and present new related research.
