Fractional Hydrodynamic Transport from the Witten Anomaly
Joe Davighi, Nakarin Lohitsiri, Napat Poovuttikul
We study the physical consequences of 't Hooft anomalies in the high-temperature limit of relativistic quantum field theories with , or more generally , global symm…
Hydrodynamic fluctuations and topological susceptibility in chiral magnetohydrodynamics
Arpit Das, Nabil Iqbal, Napat Poovuttikul
Chiral magnetohydrodynamics is devoted to understanding the late-time and long-distance behavior of a system with an Adler-Bell-Jackiw anomaly at finite temperatures. The non-conse…
A Non-Perturbative Mixed Anomaly and Fractional Hydrodynamic Transport
Joe Davighi, Nakarin Lohitsiri, Napat Poovuttikul
We present a new non-perturbative 't Hooft anomaly afflicting a quantum field theory with symmetry group in four dimensions. We use the Adams spectral s…
Higher-form symmetry and chiral transport in real-time Abelian lattice gauge theory
Arpit Das, Adrien Florio, Nabil Iqbal +1
We study classical lattice simulations of theories of electrodynamics coupled to charged matter at finite temperature, interpreting them using the higher-form symmetry formulation…
Towards an effective action for chiral magnetohydrodynamics
Arpit Das, Nabil Iqbal, Napat Poovuttikul
We consider chiral magnetohydrodynamics, i.e. a finite-temperature system where an axial current is not conserved due to an Adler-Bell-Jackiw anomaly saturated by the dynami…
Relativistic hydrodynamics with the parity anomaly
Napat Poovuttikul
We consider the hydrodynamic regime of a 2+1 dimensions QFT with the parity anomaly. Beyond the known constraints from positivity of entropy production, we show that the anomaly in…
Operator lifetime and the force-free electrodynamic limit of magnetised holographic plasma
Napat Poovuttikul, Aruna Rajagopal
Using the framework of higher-form global symmetries, we examine the regime of validity of force-free electrodynamics by evaluating the lifetime of the electric field operator, whi…
Classification of magnetohydrodynamic transport at strong magnetic field
Bartosz Benenowski, Napat Poovuttikul
Magnetohydrodynamics is a theory of long-lived, gapless excitations in plasmas. It was argued from the point of view of fluid with higher-form symmetry that magnetohydrodynamics re…
First order non-Lorentzian fluids, entropy production and linear instabilities
Napat Poovuttikul, Watse Sybesma
In this note, we investigate linear instabilities of hydrodynamics with corrections up to first order in derivatives. It has long been known that relativistic (Lorentzian) first or…
Holography and hydrodynamics with weakly broken symmetries
Sašo Grozdanov, Andrew Lucas, Napat Poovuttikul
Hydrodynamics is a theory of long-range excitations controlled by equations of motion that encode the conservation of a set of currents (energy, momentum, charge, etc.) associated…
Generalised global symmetries in states with dynamical defects: the case of the transverse sound in field theory and holography
Sašo Grozdanov, Napat Poovuttikul
In this work, we show how states with conserved numbers of dynamical defects (strings, domain walls, etc.) can be understood as possessing generalised global symmetries even when t…
Pinning of longitudinal phonons in holographic spontaneous helices
Tomas Andrade, Matteo Baggioli, Alexander Krikun +1
We consider the spontaneous breaking of translational symmetry and identify the associated Goldstone mode -- a longitudinal phonon -- in a holographic model with Bianchi VII helica…
Generalised global symmetries in holography: magnetohydrodynamic waves in a strongly interacting plasma
Sašo Grozdanov, Napat Poovuttikul
We begin the exploration of holographic duals to theories with generalised global (higher-form) symmetries. In particular, we focus on the case of magnetohydrodynamics (MHD) in str…
Universality of anomalous conductivities in theories with higher-derivative holographic duals
Sašo Grozdanov, Napat Poovuttikul
Anomalous chiral conductivities in theories with global anomalies are independent of whether they are computed in a weakly coupled quantum (or thermal) field theory, hydrodynamics,…
Shear viscosity in holography and effective theory of transport without translational symmetry
Piyabut Burikham, Napat Poovuttikul
We study the shear viscosity in an effective hydrodynamic theory and holographic model where the translational symmetry is broken by massless scalar fields. We identify the shear v…
Topological Entanglement Entropy, Ground State Degeneracy and Holography
Andrei Parnachev, Napat Poovuttikul
Topological entanglement entropy, a measure of the long-ranged entanglement, is related to the degeneracy of the ground state on a higher genus surface. The exact relation depends…
