Assessing observational constraints on dark energy
David Shlivko, Paul Steinhardt
Observational constraints on time-varying dark energy ({\it e.g.}, quintessence) are commonly presented on a - plot that assumes the equation of state of dark energy stri…

Optimal parameterizations for observational constraints on thawing dark energy
David Shlivko, Paul J. Steinhardt, Charles L. Steinhardt
Time-varying dark energy is often modeled in observational analyses through generic parameterizations of its equation of state , which typically use two free parameters $\{w_…
