Modeling the Gaia Color-Magnitude Diagram with Bayesian Neural Flows to Constrain Distance Estimates
Miles D. Cranmer, Richard Galvez, Lauren Anderson +2
We demonstrate an algorithm for learning a flexible color-magnitude diagram from noisy parallax and photometry measurements using a normalizing flow, a deep neural network capable…
A Machine Learning Dataset Prepared From the NASA Solar Dynamics Observatory Mission
Richard Galvez, David F. Fouhey, Meng Jin +8
In this paper we present a curated dataset from the NASA Solar Dynamics Observatory (SDO) mission in a format suitable for machine learning research. Beginning from level 1 scienti…
A Recommendation Algorithm to Predict Giant Exoplanet Host Stars Using Stellar Elemental Abundances
Natalie R. Hinkel, Cayman Unterborn, Stephen R. Kane +2
The presence of certain elements within a star, and by extension its planet, strongly impacts the formation and evolution of the planetary system. The positive correlation between…
Cosmology with Independently Varying Neutrino Temperature and Number
Richard Galvez, Robert J. Scherrer
We consider Big Bang nucleosynthesis and the cosmic microwave background when both the neutrino temperature and neutrino number are allowed to vary from their standard values. The…
Kahler Moduli Inflation in Type IIB Compactifications: A random tumble through the Calabi-Yau landscape
Richard Galvez
In this paper we present an initial exploration of the Calabi-Yau landscape in the context of Kahler moduli inflation. We review how the slow-roll requirement on the scalar potenti…
Supersymmetry, Nonthermal Dark Matter and Precision Cosmology
Richard Easther, Richard Galvez, Ogan Ozsoy +1
Within the Minimal Supersymmetric Standard Model (MSSM), LHC bounds suggest that scalar superpartner masses are far above the electroweak scale. Given a high superpartner mass, non…
Phase Structure of Lattice N=4 Super Yang-Mills
Simon Catterall, Poul H. Damgaard, Thomas Degrand +2
We make a first study of the phase diagram of four-dimensional N=4 super Yang-Mills theory regulated on a space-time lattice. The lattice formulation we employ is both gauge invari…
Investigating the sign problem for two-dimensional and lattice super Yang--Mills theories
Richard Galvez, Simon Catterall, Anosh Joseph +1
Recently there has been some controversy in the literature concerning the existence of a fermion sign problem in the supersymmetric Yang--Mills (SYM) theories o…
Supersymmetric gauge theories on the lattice: Pfaffian phases and the Neuberger 0/0 problem
Dhagash Mehta, Simon Catterall, Richard Galvez +1
Recently a class of supersymmetric gauge theories have been successfully implemented on the lattice. However, there has been an ongoing debate on whether lattice versions of some o…
On the sign problem in 2D lattice super Yang--Mills
Simon Catterall, Richard Galvez, Anosh Joseph +1
In recent years a new class of supersymmetric lattice theories have been proposed which retain one or more exact supersymmetries for non-zero lattice spacing. Recently there has be…
Non-abelian gauged NJL models on the lattice
Simon Catterall, Richard Galvez, Jay Hubisz +2
We use Monte Carlo simulation to probe the phase structure of a SU(2) gauge theory containing Dirac fermion flavors transforming in the fundamental representation of the grou…
Accelerating the solution of families of shifted linear systems with CUDA
Richard Galvez, Greg van Anders
We describe the GPU implementation of shifted or multimass iterative solvers for sparse linear systems of the sort encountered in lattice gauge theory. We provide a generic tool th…
Realization of Center Symmetry in Two Adjoint Flavor Large-N Yang-Mills
Simon Catterall, Richard Galvez, Mithat Unsal
We report on the results of numerical simulations of lattice Yang Mills with two flavors of (light) Wilson fermion in the adjoint representation. We analytically and numeri…
Large N QCD in two dimensions with a baryonic chemical potential
Richard Galvez, Ari Hietanen, Rajamani Narayanan
We consider large N gauge theory on a two dimensional lattice in the presence of a baryonic chemical potential. We work with one copy of naive fermion and argue that reduction hold…
