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…
Turbulent hydrodynamics in strongly correlated Kagome metals
Domenico Di Sante, Johanna Erdmenger, Martin Greiter +6
A current challenge in condensed matter physics is the realization of strongly correlated, viscous electron fluids. These fluids are not amenable to the perturbative methods of Fer…
Functional dependence of the Hall viscosity-induced transverse voltage in two-dimensional Fermi liquids
Ioannis Matthaiakakis, David Rodríguez Fernández, Christian Tutschku +3
The breaking of parity and time-reversal symmetry in two-dimensional Fermi liquids gives rise to non-dissipative transport features characterized by the Hall viscosity. In magnetic…
Strongly coupled electron fluids in the Poiseuille regime
Johanna Erdmenger, Ioannis Matthaiakakis, Rene Meyer +1
In the context of describing electrons in solids as a fluid in the hydrodynamic regime, we consider a flow of electrons in a channel of finite width, i.e.~a Poiseuille flow. The el…
