My paper "Metric-induced non-Hermitian physics" is now published in @SciPostPhys! I show how non-Hermitian skin effects and non-unitary time evolutions can emerge naturally from an effective spacetime curvature.

New #preprint: hidden localization transition where wavefunctions are localized with respect to an arbitrary combination of position and momentum. At the transition, this model describes a massless Dirac fermion in a curved spacetime.

In this recently published paper on PTEP, I show the equivalence of spacetime curvature and magnetic (gauge) fields under unitary transformations on a lattice. #physics#ptep

Today on arXiv: Topologically nontrivial multicritical points. If a plane of the parameter space only hosts nontrivial phases, localized edge modes occur at the intersections between the critical lines separating these phases. #condmat

In our recent preprint, we extend the analytical solutions describing topological zero modes localized at smooth phase boundaries to the nonhermitian case.

Published on #PTEP → exact solutions for zero modes of a modified Dirac equation decaying exponentially, or faster, or slower than exponential, for different (hermitian and nonhermitian) potential shapes.

New paper! Uncovering the link between spacetime metrics & nonhermitian physics! Contractions/expansions of spacetime correspond to gain/loss nonhermitian processes and nonunitary dynamics ⚛️

Magnetic fields (gauge) and gravitational fields (metrics) are very distinct entities. Yet, surprisingly, they are equivalent under a "rotation" combining position and momentum

Exact solutions for topological zero modes at smooth and exponentially-confined boundaries. This generalizes the exact solutions of Dirac equations with domain walls, i.e., Jackiw-Rebbi solitons.
