Dr. Yi-Hsuan Chen

Defense Date: 11/22/2019

Dissertation Title: Influences of Surface Spectral Emissivity and Cloud Longwave Scattering on Climate Simulations

Faculty Advisor: Asst. Prof. Xianglei Huang

Dr. Chen is seeking a postdoc position.  After he finishes his postdoc, he plans to find a faculty position in Taiwan.

Dr. Mojtaba Akhavan-Tafti

Defense Date: 11/25/2019

Dissertation Title: Evolution of Flux Transfer Events at the Magnetopause: MMS Observations and Global Hybrid-Vlasov Simulations

Faculty Advisor: Prof. James Slavin

Dr. Akhavan-Tafti has accepted a joint-appointment post-doctoral fellowship here at Climate & Space and the Laboratoire de Physique des Plasmas (LPP) at École Polytechnique, France. His research will focus on solar wind and magnetic reconnection drivings of interplanetary and planetary dynamics, using spacecraft observations and global simulations.

Dr. Daniel Vech

Defense Date: 11/26/2019

Dissertation Title: Transition of Solar Wind Turbulence from MHD to Kinetic Scales

Faculty Advisor: Prof. Justin Kasper

In January, Dr. Vech will join the Laboratory for Atmospheric and Space Physics at CU Boulder as a postdoctoral researcher. His primary duty will be to study kinetic scale physics and wave-particle interaction with NASA’s Parker Solar Probe data.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
