Hall Angle of a Spatially Random Vector Model
Yi-Li Wang, Young-Kwon Han, Xian-Hui Ge +1
Strange metals exhibit linear resistivity and anomalous Hall transport, yet a comprehensive theory that accounts for both phenomena is still lacking. Recent studies have shown SYK-…
Linear-T Resistivity from Spatially Random Vector Coupling
Yi-Li Wang, Xian-Hui Ge, Sang-Jin Sin
Recently, Patel et al. introduced a higher dimensional version of the SYK model with random coupling in a Yukawa interaction to find the linear- resistivity. We test the univers…
Effective anisotropic dynamics in Group Field Theory cosmology
Daniele Oriti, Yi-Li Wang
We study the emergent dynamics of an anisotropic universe in the context of Group Field Theory condensate cosmology, with a scalar field playing the role of a relational clock. Acc…
Generalised Amit-Roginsky model from perturbations of 3d quantum gravity
Victor Nador, Daniele Oriti, Xiankai Pang +2
A generalised Amit-Roginsky vector model in flat space is obtained as the effective dynamics of pertubations around a classical solution of the Boulatov group field theory for 3d e…
Spherically-symmetric geometries in a matter reference frame as quantum gravity condensates
Daniele Oriti, Yi-Li Wang
Candidate microstates of a spherically symmetric geometry are constructed in the group field theory formalism for quantum gravity, for models including both quantum geometric and s…
Black holes in 4D Einstein-Maxwell-Gauss-Bonnet gravity coupled with scalar fields
Yi-Li Wang, Xian-Hui Ge
Einstein-Maxwell-Gauss-Bonnet-axion theory in -dimensional spacetime is investigated in this paper through a "Kaluza-Klein-like" process. Dual to systems at finite temperature w…
Violation of the viscosity/entropy bound in translationally invariant non-Fermi liquids
Xian-Hui Ge, Shao-Kai Jian, Yi-Li Wang +2
The shear viscosity is an important characterization of how a many-body system behaves like a fluid. We study the shear viscosity in a strongly interacting solvable model, consisti…
Shear Viscosity to Entropy Density Ratio in Higher Derivative Gravity with Momentum Dissipation
Yi-Li Wang, Xian-Hui Ge
We investigate in linear scalar fields modified Gauss-Bonnet theory that breaks translation invariance. We first calculate both analytically and numerically and show it…
