Mixed axial-gravitational anomaly from emergent curved spacetime in nonlinear charge transport
Tobias Holder, Daniel Kaplan, Roni Ilan +1
In 3+1 dimensional spacetime, two vector gauge anomalies are known: The chiral anomaly and the mixed axial-gravitational anomaly. While the former is well documented and tied to th…
Electrons flow like falling cats: Deformations and emergent gravity in quantum transport
Tobias Holder
The effective low-energy excitations in a metallic or semimetallic crystalline system (i.e. electronic quasiparticles) always have a finite spatial extent. It is self-evident but v…
Bound on resistivity in flat-band materials due to the quantum metric
Johannes Mitscherling, Tobias Holder
The quantum metric is a central quantity of band theory but has so far not been related to many response coefficients due to its nonclassical origin. However, within a newly develo…
Unconventional superconductivity in systems with annular Fermi surfaces: Application to rhombohedral trilayer graphene
Areg Ghazaryan, Tobias Holder, Maksym Serbyn +1
We show that in a two-dimensional electron gas with an annular Fermi surface, long-range Coulomb interactions can lead to unconventional superconductivity by the Kohn-Luttinger mec…
Proposal for realizing anomalous Floquet insulators via Chern band annihilation
Carolyn Zhang, Tobias Holder, Netanel H. Lindner +2
Two-dimensional periodically driven systems can host an unconventional topological phase unattainable for equilibrium systems, termed the Anomalous Floquet-Anderson insulator (AFAI…
Half and quarter metals in rhombohedral trilayer graphene
Haoxin Zhou, Tian Xie, Areg Ghazaryan +8
Ferromagnetism is most common in transition metal compounds but may also arise in low-density two-dimensional electron systems, with signatures observed in silicon, III-V semicondu…
