On the introduction of a boundary in topological field theories
Andrea Amoretti, Alessandro Braggio, Giacomo Caruso +2
We study the consequences of the presence of a boundary in topological field theories in various dimensions. We characterize, univocally and on very general grounds, the field cont…
Bounds on charge and heat diffusivities in momentum dissipating holography
Andrea Amoretti, Alessandro Braggio, Nicodemo Magnoli +1
Inspired by a recently conjectured universal bound for thermo-electric diffusion constants in quantum critical, strongly coupled systems and relying on holographic analytical compu…
Analytic DC thermo-electric conductivities in holography with massive gravitons
Andrea Amoretti, Alessandro Braggio, Nicola Maggiore +2
We provide an analytical derivation of the thermo-electric transport coefficients of the simplest momentum-dissipating model in gauge/gravity where the lack of momentum conservatio…
Thermo-electric transport in gauge/gravity models with momentum dissipation
Andrea Amoretti, Alessandro Braggio, Nicola Maggiore +2
We present a systematic definition and analysis of the thermo-electric linear response in gauge/gravity systems focusing especially on models with massive gravity in the bulk and t…
Holography in flat spacetime: 4D theories and electromagnetic duality on the border
Andrea Amoretti, Alessandro Braggio, Giacomo Caruso +2
We consider a free topological model in 5D euclidean flat spacetime, built from two rank-2 tensor fields. Despite the fact that the bulk of the model does not have any particular p…
