MGKDB: An IMAS-aligned multicode gyrokinetic simulation database for reproducible fusion turbulence modeling and data-driven analysis
Craig Michoski, David R. Hatch, Dongyang Kuang +14
Expensive fusion simulations are commonly preserved in code-specific formats that limit discovery, comparison, and reuse. We present the Multiscale GyroKinetic DataBase (MGKDB), an…
Confinement transition to gravitational waves in the one-flavor Hyper Stealth Dark Matter theory
V. Ayyar, R. C. Brower, G. T. Fleming +11
The thermodynamics of the gauge theory with a single flavor of fundamental quarks is analyzed on the lattice with dynamical fermion simulations, which is the low-energy sec…
Finite Temperature Transition in Hyper Stealth Dark Matter using Möbius Domain Wall Fermions
Venkitesh Ayyar, Nobuyuki Matsumoto, Aaron S. Meyer +1
The first-order confinement transition of a strongly coupled composite dark matter theory can provide a possible source of gravitational waves in the early universe. In this work,…
Exploring Composite Dark Matter with an SU(4) gauge theory with 1 fermion flavor
Venkitesh Ayyar, LSD collaboration
Several SU(N) gauge theories have been explored as candidates for producing stable dark matter particles that can explain their relative abundance, while also evading current const…
The Operator Product Expansion for Radial Lattice Quantization of 3D Theory
Venkitesh Ayyar, Richard C. Brower, George T. Fleming +4
At its critical point, the three-dimensional lattice Ising model is described by a conformal field theory (CFT), the 3d Ising CFT. Instead of carrying out simulations on Euclidean…
Optimizing Staggered Multigrid for Exascale performance
Venkitesh Ayyar, Richard Brower, M. A. Clark +2
Adaptive multi-grid methods have proven very successful in dealing with critical slow down for the Wilson-Dirac solver in lattice gauge theory. Multi-grid algorithms developed for…
