Bradley group paper published in Physical Review E

July 26, 2019

Nanoscale patterns produced by bombarding a surface with an ion beam When an energetic ion strikes a solid surface, one or more atoms can be ejected from the solid. Bombarding a flat solid surface with a broad ion beam therefore results in erosion of the solid. Naively, one would expect that the solid surface would [Read More...]

Ross group paper published in PRL

July 11, 2019

Evidence for Bose-Einstein Condensation in a Rare-Earth Magnet The Bose-Einstein condensate (BEC) state, where almost of the particles in a system “condense” into the lowest available energy state, is a fifth state of matter after solids, liquids, gasses, and plasmas. Quantum magnets are known to be able to host BECs of “triplons”, which are quasi-particles [Read More...]

“Odd and Even Linear Magnetoresistances at Low Field” Yejun Feng Okinawa Institure of Science and Technology Thursday, May 2nd, 2019 at 10:00 am LSC room 308 Onsager’s relationship governs the galvanomagnetic behavior as σij(H) = σji(−H), which in the low field limit, typically leads to quadratic field dependence. Here I discuss two scenarios where linear [Read More...]

Colloquium: Gary Feldman

April 30, 2019

“Neutrino Oscillations” Gary Feldman Harvard University Monday May 6th, 2019 at 4:00 PM 120 Engineering (Hammond Auditorium) Of the fundamental particles of nature, neutrinos are the least understood.  Much, but not all, of what we want to learn about them can be obtained from the study of their peculiar habit of morphing from one species to [Read More...]

Colloquium: Kate Scholberg

April 23, 2019

“Detecting the Tiny Thump of the Neutrino” Kate Scholberg Duke University Monday April 29th, 2019 at 4:00 PM 120 Engineering (Hammond Auditorium) Neutrinos interact only rarely with matter. Coherent elastic neutrino-nucleus scattering (CEvNS) was first predicted in 1974; it’s a process in which a neutrino scatters off an entire nucleus. By neutrino standards, CEvNS occurs [Read More...]
