PINNs for N=2* holography
Alex Buchel
Can a holographic theory be reconstructed from its equation of state? We investigate this question using physics-informed neural networks in the bosonic-mass sector of the Pilch--W…
Holographic Charged Transport with Higher Derivatives
Alex Buchel, Sera Cremonini, Mohammad Moezzi +1
We compute the first-order hydrodynamic transport coefficients (shear viscosity , bulk viscosity , and charge conductivity ) for a broad class of strongly coupled, four-di…
Holographic Gauss-Bonnet transport
Alex Buchel
We extend the computational framework of \cite{Buchel:2023fst} to analysis of shear and bulk viscosities in generic strongly coupled holographic Gauss-Bonnet gauge theories. The fi…
Holographic conformal order with higher derivatives
Alex Buchel
Conformal order are isotropic and translationary invariant thermal states of a conformal theory with nonzero expectation value of certain operators. While ubiquitous in bottom-up m…
Holographic transport beyond the supergravity approximation
Alex Buchel, Sera Cremonini, Laura Early
We set up a unified framework to efficiently compute the shear and bulk viscosities of strongly coupled gauge theories with gravitational holographic duals involving higher derivat…
