Hydrodynamics of dipole-conserving fluids
Aleksander Głódkowski, Francisco Peña-Benítez, Piotr Surówka
Dipole-conserving fluids serve as examples of kinematically constrained systems that can be understood on the basis of symmetry. They are known to display various exotic features i…
Space-dependent symmetries and fractons
Kevin T. Grosvenor, Carlos Hoyos, Francisco Peña-Benitez +1
There has been a surge of interest in effective non-Lorentzian theories of excitations with restricted mobility, known as fractons. Examples include defects in elastic materials, v…
Fractons, symmetric gauge fields and geometry
Francisco Peña-Benitez
Gapless fracton phases are characterized by the conservation of certain charges and their higher moments. These charges generically couple to higher rank gauge fields. In this pape…
Hydrodynamics of ideal fracton fluids
Kevin T. Grosvenor, Carlos Hoyos, Francisco Peña-Benítez +1
Low-energy dynamics of many-body fracton excitations necessary to describe topological defects should be governed by a novel type of hydrodynamic theory. We use a Poisson bracket a…
Super-resonant transport of topological surface states subjected to in-plane magnetic fields
Song-Bo Zhang, Chang-An Li, Francisco Peña-Benitez +4
Magnetic oscillations of Dirac surface states of topological insulators are expected to be associated with the formation of Landau levels or the Aharonov-Bohm effect. We instead st…
Critical scaling of the AC conductivity and momentum dissipation
N. Angelinos, E. Kiritsis, F. Peña-Benitez
The scaling of the AC conductivity in quantum critical holographic theories at finite density, finite temperature and in the presence of momentum dissipation is considered. It is s…
Quantum Hall effective action for anisotropic Dirac semi-metal
Carlos Hoyos, Ruben Lier, Francisco Peña-Benitez +1
We present a study of Hall transport in semi-Dirac critical phases. The construction is based on a covariant formulation of relativistic systems with spatial anisotropy. Geometric…
Hall Viscosity in a Strongly Coupled Magnetized Plasma
Carlos Hoyos, Francisco Peña-Benitez, Piotr Witkowski
We show how a Hall viscosity induced by a magnetic field can be generated in strongly coupled theories with a holographic dual. This is achieved by considering parity-breaking high…
Non-Abelian anomalies in multi-Weyl semimetals
Renato M. A. Dantas, Francisco Peña-Benitez, Bitan Roy +1
We construct the effective field theory for time-reversal symmetry breaking multi-Weyl semimetals (mWSMs), composed of a single pair of Weyl nodes of (anti-)monopole charge , wi…
Berry curvature and Hall viscosities in an anisotropic Dirac semi-metal
Francisco Pena-Benitez, Kush Saha, Piotr Surowka
We investigate parity-odd non-dissipative transport in an anisotropic Dirac semi-metal in two spatial dimensions. The analysis is relevant for interacting electronic systems with m…
Magnetotransport in multi-Weyl semimetals: A kinetic theory approach
Renato M. A. Dantas, Francisco Peña-Benitez, Bitan Roy +1
We study the longitudinal magnetotransport in three-dimensional multi-Weyl semimetals, constituted by a pair of (anti)-monopole of arbitrary integer charge (), with and…
AC conductivity for a holographic Weyl Semimetal
Gianluca Grignani, Andrea Marini, Francisco Pena-Benitez +1
We study the AC electrical conductivity at zero temperature in a holographic model for a Weyl semimetal. At small frequencies we observe a linear dependence in the frequency. The m…

We performed a study of the perturbative instabilities in Einstein-Maxwell-Chern-Simons theory with a gravitational Chern-Simons term, which is dual to a strongly coupled field the…

Elias Kiritsis, Francisco Peña-Benitez
The frequency dependence of the AC conductivity is studied in a holographic model of a non-fermi liquid that is amenable to both analytical and numerical computation. In the regime…

Karl Landsteiner, Eugenio Megias, Francisco Pena-Benitez
Axial anomalies give rise to interesting new transport phenomena such as the "chiral magnetic effect". We discuss how the associated transport coefficients can be studied via Kubo…
