Measurements of the Hall coefficient, resistivity, magnetoresistance, magnetic response and thermopower in two-dimensional strongly interacting electron systems have established that, contrary to expectations, a metal-insulator transition occurs at a critical electron density nc and a metallic phase exists in 2-D. One intriguing mystery has been that, by contrast with the dramatic divergences that have been observed for all other physical properties, the magnetoresistance has exhibited smooth and uneventful behavior approaching and crossing nc.
In this talk, I will present new data and a different new analysis of the magnetoresistance of the strongly interacting 2-D electron system in a silicon MOSFET for a broad range of electron densities. Our surprising results should trigger a re-examination of past work.
All welcome for a discussion about “Queer Rights and the Courts: The Meaning of Sex, Sexual Orientation, and Transgender Status,” with Jennifer Levi, director of the Transgender Rights Project at GLBTQ Legal Advocates and Defenders and professor of law at Western New England University, and Jen Manion, associate professor of history, Amherst College.
Whether you have meditated for a long time or have never meditated, come join us for this time of practice together. Come to relax, quiet your mind, learn how to experience less suffering and stress, explore Buddhist philosophy and psychology, or just talk about what it means to live from compassion and awareness or because you are curious. The group will be led by Buddhist Advisor Mark Hart.
