Field theory of higher-order topological crystalline response, generalized global symmetries and elasticity tetrads
Jaakko Nissinen
We discuss the higher-order topological field theory and response of topological crystalline insulators with no other symmetries. We show how the topology and geometry of the syste…
Torsional Landau levels and geometric anomalies in condensed matter Weyl systems
Sara Laurila, Jaakko Nissinen
We consider the role of coordinate dependent tetrads ("Fermi velocities"), momentum space geometry, and torsional Landau levels (LLs) in condensed matter systems with low-energy We…
On thermal Nieh-Yan anomaly in topological Weyl materials
J. Nissinen, G. E. Volovik
We discuss the possibility of a gravitional Nieh-Yan anomaly of the type in topological Weyl materials, where is temperature…
On thermal Nieh-Yan anomaly in Weyl superfluids
J. Nissinen, G. E. Volovik
We discuss the possibility of the torsional Nieh-Yan anomaly of the type in Weyl superfluids, where is temperature and ${\cal T}…
Emergent spacetime and gravitational Nieh-Yan anomaly in chiral Weyl superfluids and superconductors
Jaakko Nissinen
Momentum transport is anomalous in chiral superfluids and superconductors in the presence of textures and superflow. Using the gradient expansion of the semi-classical appro…
Elasticity tetrads, mixed axial-gravitational anomalies, and 3+1d quantum Hall effect
J. Nissinen, G. E. Volovik
For two-dimensional topological insulators, the integer and intrinsic (without external magnetic field) quantum Hall effect is described by the gauge anomalous (2+1)-dimensional [2…
