Entangled states as a probe of early universe history: a Higgs case study

Rose Baunach

I explore whether distinguishing features of phase transitions and/or the inflationary energy scale can be imprinted on cosmological observables due to entanglement during inflation, given a spectator scalar field with a Higgs-like potential. As a consequence of this analysis, I also present results that illustrate the variety of features a Higgs-like spectator can imprint on the primordial power spectrum due to entanglement, as well as how easy it might be to distinguish such spectra from other similar scalar field results at the level of CMB residuals. I utilize the technical framework for dynamically generated entangled states developed in ( arXiv:2211.11079 [hep-th] , arXiv:2104.13410 [hep-th] ) to obtain my results.

RG and BV-formalism

P. Lavrov

In present paper a quantization scheme proposed recently by Morris (arXiv:1806.02206[hep-th]) is analyzed. This method is based on idea to combine the renormalization group with the BV-formalism in an unique quantization procedure. It is shown that the BV-formalism and the new method should be considered as independent approaches to quantization of gauge systems both provided by global supersymmetry.

Generalized entropies and the expansion law of the universe

F. L. Dezaki, B. Mirza

We suggest that using the first law of thermodynamics is a convenient method to obtain a correct form of the expansion law of the universe (Padmanabhan, arXiv:1206.4916v1 [hep-th]). We will, then, use this idea to obtain the expansion law for a Kodama observer. By using the expansion law for a Kodama observer, we can obtain the dynamic equation of the FRW universe for deformed Horava–Lifshitz gravity. The use of the first law of thermodynamics also leads to a new approach for obtaining the Friedmann equations for f(R) and scalar tensor gravities.
