Stochastic scalar-tensor inflation and beyond
Extends the stochastic formalism for how quantum vacuum fluctuations become classical during inflation to scalar-tensor theories, covering Gauss-Bonnet, generalized Brans-Dicke, Horndeski and braiding theories, plus multifield coarse-graining in full General Relativity.
Fairness-Aware Test-Time Prompt Tuning
A test-time prompt tuning method for improving fairness in language model outputs without retraining the underlying model, developed during a machine learning placement at Featurespace.
Bunch-Davies initial conditions and non-perturbative inflationary dynamics in Numerical Relativity
Shows that realistic inhomogeneities during inflation can be simulated with Numerical Relativity from stochastic Bunch-Davies-consistent initial conditions, across a quadratic potential, an inflection-point potential, and a strong resonance model.
Quantitative classicality in cosmological interactions during inflation
Introduces a quantitative 'quantum interactivity' measure for when classical descriptions of inflationary perturbations suffice, showing non-linear contributions can be accurately described classically even before horizon crossing.
N-representable one-electron reduced density matrices reconstruction at non-zero temperatures
Reconstructs one-electron reduced density matrices from X-ray structure factors and Compton profiles while accounting for atomic thermal motion, using Semi-Definite Programming to recover static, N-representable matrices from experimental data at non-zero temperature.
