Including a Warm Corona within the Inner Accretion Disk of Active Galactic Nuclei
Warm coronae, Comptonizing regions of warm (temperature kT ∼ 1keV), and optically thick (Thomson depth ∼ 10 - 20) gas, at the surfaces of accretion disks in active galactic nuclei (AGNs), have been proposed to explain the ... -
Methods for model reduction in cardiac dynamics
(Georgia Institute of Technology, 2022-05-05)Mathematical models have been crucial for understanding biological systems because they help us organize our knowledge about the system and allow us to not only test new ideas without harming or perturbing expensive in ... -
SHORTCUT TO TARGET STATES IN A SPIN-1 BOSE-EINSTEIN CONDENSATE
We generate spin squeezed ground states in an atomic spin-1 Bose-Einstein condensate tuned near the quantum critical point between the polar and ferromagnetic quantum phases of the interacting spin ensemble. In contrast ... -
Rate-dependent Locomotion and Intrusion Phenomena in Granular Media
(Georgia Institute of Technology, 2022-04-28)In movement on solid terrains, animals, vehicles, and robots can make use of well-established contact dynamics for planning movement and locomotion gaits. However, when the terrain can be deformed significantly, effective ... -
Investigation of spatiotemporal chaos using persistent homology
(Georgia Institute of Technology, 2022-01-04)Spatiotemporal chaos, especially fluid turbulence, is ubiquitous in nature but can be difficult to characterize because analytic solutions of the strongly nonlinear partial differential equations that govern the behavior ... -
Molecular dynamics simulations for thermoelectric materials
(Georgia Institute of Technology, 2021-01-04)High temperature copper chalcogenides such as Cu2S are promising thermoelectric materials due to the combination of a solid S lattice and liquid Cu atoms in the context of the so-called phonon-liquid electron-crystal (PLEC) ... -
Rigidity percolation in a random tensegrity via analytic graph theory
(2022-04-19)Tensegrities are mechanical structures that include cable-like elements that are strong and lightweight relative to rigid rods yet support only extensile stress. From suspension bridges to the musculoskeletal system to ... -
Compact Penning Traps for Quantum Science with Cold Atomic Ions
(Georgia Institute of Technology, 2022-04-11)Penning ion traps are useful experimental platforms for quantum simulation, mass spectrometry, precision metrology, and molecular ion spectroscopy. The GTRI Quantum Systems Division (QSD) has developed a compact, ... -
Feynman rules for wave turbulence
(2022-04-12)It has long been known that weakly nonlinear field theories can have a late-time stationary state that is not the thermal state, but a wave turbulent state (the Kolmogorov-Zakharov state) with a far-from-equilibrium cascade ... -
Opportunities Created by Spin-Orbit Interactions
(Georgia Institute of Technology, 2022-04-04)Effects of spin-orbit interactions in condensed matter are an important and rapidly evolving topic. A sea change occurred with the discovery of spin-orbit interactions in graphene by Mele and Kane, which has led to the ... -
Optical Lattice Clocks: From Timekeepers to Spies of the Quantum Realm
(Georgia Institute of Technology, 2022-03-28)Harnessing the behavior of complex systems is at the heart of quantum technologies. Precisely engineered ultracold gases are emerging as a powerful tool for this task. In this talk I will explain how ultracold strontium ... -
Protecting the Space Environment: Sustainability and Security
(Georgia Institute of Technology, 2022-03-07)In recent years, the number of objects in space has grown rapidly, and this growth is projected to continue to accelerate over the next decade. There has also been increased military activity in space, including rendezvous ... -
Exact Coherent Structures in turbulent small-aspect-ratio Taylor-Couette flow
(Georgia Institute of Technology, 2019-07-15)Turbulent flows are ubiquitous, so understanding their nature and dynamics and the ability to make definitive predictions about their behavior is of tremendous practical importance. Substantial progress in this direction ... -
Testing General Relativity and Probing Nuclear Physics in the era of Gravitational Waves
(Georgia Institute of Technology, 2021-12-14)The LIGO and Virgo detectors have detected 90 gravitational wave events so far. The gravitational waves have come from pairs of black holes or neutron stars. The astrophysical interpretation of these events was made possible ... -
SPATIOTEMPORAL IMPACT OF PHAGE EXPOSURE ON BIOFILM SYSTEMS
(Georgia Institute of Technology, 2021-12-14)When single-celled prokaryotic organisms, one of the simplest forms of life, develop the ability to exhibit complex emergent properties such as social cooperation, resource capture, and enhanced survivability, the individual ... -
Exact Coherent Structures and Data-Driven Modeling in a Two-Dimensional Fluid
(Georgia Institute of Technology, 2021-12-14)Turbulence is one of the most ubiquitous features of the world around us. Its signatures can be found at every scale, in the small eddies of streams to the vortex wakes of airliners, from ocean currents to the cosmic swirls ... -
The Edge States of Epitaxial Graphene on SiC
