The physical meaning of the Belinfante-Rosenfeld ambiguity
Ioannis Matthaiakakis
Current literature lacks consensus on how to theoretically describe spin polarization and its transport in matter. The underlying reason is the presence of the Belinfante-Rosenfeld…
The chiral torsional anomaly and the Nieh-Yan invariant with and without boundaries
Johanna Erdmenger, Ioannis Matthaiakakis, René Meyer +1
There exists a long-standing debate regarding the torsion contribution to the 4d chiral anomaly of a Dirac fermion. Central to this debate is the Nieh-Yan anomaly, which has been c…
Relaxation terms for anomalous hydrodynamic transport in Weyl semimetals from kinetic theory
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +2
We consider as a model of Weyl semimetal thermoelectric transport a -dimensional charged, relativistic and relaxed fluid with a chiral anomaly. We…
Restoring time-reversal covariance in relaxed hydrodynamics
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1
In hydrodynamics, for generic relaxations, the stress tensor and charge current two-point functions are not time-reversal covariant. This remains true even if the Martin-Kad…
Gibbons-Hawking-York boundary terms and the generalized geometrical trinity of gravity
Johanna Erdmenger, Bastian Heß, Ioannis Matthaiakakis +1
General relativity (GR) as described in terms of curvature by the Einstein-Hilbert action is dynamically equivalent to theories of gravity formulated in terms of spacetime torsion…
Universal Gibbons-Hawking-York term for theories with curvature, torsion and non-metricity
Johanna Erdmenger, Bastian Heß, Ioannis Matthaiakakis +1
Motivated by establishing holographic renormalization for gravitational theories with non-metricity and torsion, we present a new and efficient general method for calculating Gibbo…
Leading order magnetic field dependence of conductivities in anomalous hydrodynamics
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1
We show that literature results claimed for the magnetic field dependence of the longitudinal conductivity in anomalous first-order hydrodynamics are frame dependent at this deriva…
Non-dissipative electrically driven fluids
Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1
Existing hydrodynamic models of charged fluids consider any external electric field acting on the fluid as either first order in the hydrodynamic derivative expansion and completel…
Quantum Complexity as Hydrodynamics
Pablo Basteiro, Johanna Erdmenger, Pascal Fries +3
As a new step towards defining complexity for quantum field theories, we map Nielsen operator complexity for gates to two-dimensional hydrodynamics. We develop a tractable…
