R. G. Herb Condensed Matter Seminar
2D Electronics, Layer by Layer
Time: 10:00 am
Place: 5310 Chamberlin
Speaker: Shawna Hollen, UNH
Abstract: Two-dimensional materials now form the basis for a broad and rich field of research bristling with exciting possible applications from photonics to quantum computing and leading to discoveries of new phenomena due to the high customizability of the materials systems and interactions within them. Research in the Hollen lab focuses on understanding the role of defects, disorder, and interlayer interactions in determining the electronic properties of 2D crystals using scanning tunneling microscopy (STM). In this talk, I will focus on projects where we are studying the degradation of 2D layers at the atomic scale, the role of dynamics and interlayer interactions in determining a collective ground state, and extending our experimental tools to nanosecond time-resolution.

Astronomy Colloquium
White Dwarf Binaries across the H-R diagram
Time: 3:30 pm
Place: Sterling Hall 4421
Speaker: Dr. Borja Anguiano, University of Notre Dame
Abstract: The evolution of multiple-star systems is a fundamental question in stellar astrophysics where around 25% of the binary systems are compact enough to exchange mass, changing the structures and subsequent evolution of both stars. Muti-object-wavelength-epoch massive stellar spectroscopic surveys are opening a new era to study the properties of compact binaries across the H-R diagram. In this talk I discuss the recent APOGEE-GALEX-Gaia Catalog (AGGC) of candidate compact binaries containing potential WD stars. Numbering over 3400 sources, the size of this catalog is comparable to that of previous WDMS catalogs but includes secondary companions in the MS, subgiant branch, RGB, and red clump (RC) phases of evolution, as well as systems that occupy the MS binary and sub-subgiant (SSG) regions of the H-R diagram.
