Higgs Criticality beyond the Standard Model
Thomas Steingasser, David I. Kaiser
Both parameters in the Higgs field's potential, its mass and quartic coupling, appear fine-tuned to near-critical values, which gives rise to the hierarchy problem and the metastab…
Planck Constraints and Gravitational Wave Forecasts for Primordial Black Hole Dark Matter Seeded by Multifield Inflation
Wenzer Qin, Sarah R. Geller, Shyam Balaji +2
We perform a Markov Chain Monte Carlo (MCMC) analysis of a simple yet generic multifield inflation model characterized by two scalar fields coupled to each other and nonminimally c…
Flows into de Sitter space from anisotropic initial conditions: An effective field theory approach
Feraz Azhar, David I. Kaiser
For decades, physicists have analyzed various versions of a ``cosmic no-hair" conjecture, to understand under what conditions a spacetime that is initially spatially anisotropic an…
Primordial Black Holes from Multifield Inflation with Nonminimal Couplings
Sarah R. Geller, Wenzer Qin, Evan McDonough +1
Primordial black holes (PBHs) provide an exciting prospect for accounting for dark matter. In this paper, we consider inflationary models that incorporate realistic features from h…
Beyond Schrödinger-Poisson: Nonrelativistic Effective Field Theory for Scalar Dark Matter
Borna Salehian, Hong-Yi Zhang, Mustafa A. Amin +2
Massive scalar fields provide excellent dark matter candidates, whose dynamics are often explored analytically and numerically using nonrelativistic Schrödinger-Poisson (SP) equati…
Tackling Loopholes in Experimental Tests of Bell's Inequality
David I. Kaiser
Bell's inequality sets a strict threshold for how strongly correlated the outcomes of measurements on two or more particles can be, if the outcomes of each measurement are independ…
