Consistency of Scalar and Vector Effective Field Theories
Victor Pozsgay
In the absence of a theory of everything, modern physicists need to rely on other predictive tools and turned to Effective Field Theories (EFTs) in a number of fields, including bu…
Positivity-causality competition: a road to ultimate EFT consistency constraints
Mariana Carrillo González, Claudia de Rham, Sumer Jaitly +2
Effective field theories (EFT) are strongly constrained by fundamental principles such as unitarity, locality, causality, and Lorentz invariance. In this paper, we consider the EFT…
To Half--Be or Not To Be?
Claudia de Rham, Sebastian Garcia-Saenz, Lavinia Heisenberg +2
It has recently been argued that half degrees of freedom could emerge in Lorentz and parity invariant field theories, using a non-linear Proca field theory dubbed Proca-Nuevo as a…
Causal Effective Field Theories
Mariana Carrillo Gonzalez, Claudia de Rham, Victor Pozsgay +1
Physical principles such as unitarity, causality, and locality can constrain the space of consistent effective field theories (EFTs) by imposing two-sided bounds on the allowed val…
Cosmology of a new class of massive vector fields
Victor Pozsgay
I introduce (Extended) Proca-Nuevo, a non-linear theory of a massive spin-1 field enjoying a non-linearly realized constraint. I will provide a covariantization scheme that allows…
Cosmology of Extended Proca-Nuevo
Claudia de Rham, Sebastian Garcia-Saenz, Lavinia Heisenberg +1
Proca-Nuevo is a non-linear theory of a massive spin-1 field which enjoys a non-linearly realized constraint that distinguishes it among other generalized vector models. We show th…
New class of Proca interactions
Claudia de Rham, Victor Pozsgay
We propose a new class of Proca interactions that enjoy a non-trivial constraint and hence propagates the correct number of degrees of freedom for a healthy massive spin-1 field. W…
SYK-like tensor quantum mechanics with symmetry
Sylvain Carrozza, Victor Pozsgay
We introduce a family of tensor quantum-mechanical models based on irreducible rank- representations of . In contrast to irreducible tensor models with $\mathrm{…
Covariance Bell inequalities
Victor Pozsgay, Flavien Hirsch, Cyril Branciard +1
We introduce Bell inequalities based on covariance, one of the most common measures of correlation. Explicit examples are discussed, and violations in quantum theory are demonstrat…
