Characterizing Heliospheric and Interstellar Interactions Using Pickup Ion Measurements
(2022)
The Heliosphere, orbiting the galactic center of the Milky Way, is a plasma bubble carved out of the Local Interstellar Medium (LISM) by the Sun's dynamic and magnetic influence. Its relative motion creates a steady inflow ...
Dynamics of the Jovian Magnetosphere: Combining Insights from Global MHD Simulations and In Situ Measurements From the Juno Spacecraft
(2021)
Unlike the terrestrial magnetosphere, which responds strongly to changes in the solar wind and interplanetary magnetic field, Jupiter's magnetosphere depends largely on internal processes related to its strong planetary ...
Thermoelectric Transport in Disordered Materials
(2022)
Material disorder comes in two forms, dynamic energetic disorder and static energetic disorder, both of which can greatly influence charge and thermoelectric (TE) transport properties by altering the energy dependences of ...
Investigating Plasma Interactions with Multiphase Surfaces using Computational Models
(2022)
Low-temperature plasmas affect multiphase surfaces in contact with the plasma, and the surfaces can in turn affect the plasma. These effects can be destructive (i.e., erosion) or productive (i.e., increased reactive species ...
Generation, Optimization and Amplification of Ultrashort Infrared Pulses
(2023)
The development of few-cycle, ultra-intense laser sources in the long-wave infrared (LWIR, 8–12 μm) is of keen interest in many research fields, including molecular spectroscopy in the “fingerprint” region, laser-induced ...
Next Generation Graphene Photonics Enabled by Ultrafast Light-Matter Interactions and Machine Learning
(2021)
Graphene was first experimentally studied in 2004, featuring an atomically-thin structure. Since then, many unique photonic and electrical properties of graphene and other 2D materials were reported. However, additional ...
High-Energy-Density Field-Reversed Configurations for Sub-Microsecond Magnetized Target Fusion
(2023)
Magnetized target fusion (MTF) has gained popularity in recent decades as potentially a more economic route to fusion gain greater than unity in the laboratory. The magnetized liner inertial fusion (MagLIF) program on the ...
Engineering Excitonic Properties in van der Waals Solids Using Strain
(2022)
While electronics sits at the forefront of logic processing and data communication in microprocessors, the ever-increasing trend of on-chip power density has rendered the sustainability of device scaling questionable. This ...
Large-Scale Simulations of Complex Turbulent Flows: Modulation of Turbulent Boundary Layer Separation and Optimization of Discontinuous Galerkin Methods for Next-Generation HPC Platforms
(2020)
The separation of spatially evolving turbulent boundary layer flow near regions of adverse pressure gradients has been the subject of numerous studies in the context of flow control. Although many studies have demonstrated ...
From Atoms to Devices: Performance Bottlenecks of Nitride Semiconductors Using Multi-Scale Quantum Methods
(2023)
III-nitride semiconductors have revolutionized modern electronics by enabling high-power radio-frequency and lighting technologies. These materials hold immense potential for new technologies such as miniaturized displays, ...
