Explore a physics seminar from Harvard University researcher Rashmish Mishra examining holographic phase transitions in the early universe and their implications for observable gravitational wave signals. Delve into the study of strongly coupled confining theories within Beyond Standard Model (BSM) frameworks, focusing on confinement-deconfinement phase transitions analyzed through AdS/CFT correspondence in the Randall-Sundrum framework. Learn about the challenges of supercooling periods in traditional models and their impact on Big Bang Nucleosynthesis (BBN), while discovering new modifications that address these issues through systematic incorporation of strong IR effects. Understand the latest research findings from papers 2309.10090 and 2401.09633, offering fresh perspectives on early universe cosmological phenomena and their potential observational signatures.
