Abelian spectral topology of multifold exceptional points
Physical Review ResearchThe advent of non-Hermitian physics has enriched the plethora of topological phases to include phenomena without Hermitian counterparts. Despite being among the most well-studied uniquely non-Hermitian features, the topological properties of multifold ...

Bousfield localisations along Quillen bifunctors and applications [PDF]
, 2014 We describe left and right Bousfield localisations along Quillen adjunctions of two variables. These localised model structures can be used to define Postnikov sections and homological localisations of arbitrary model categories, and to study the ...

Spectral topologies on skew braces
, 2022 Using a new definition of a prime ideal of a skew brace A, on set Spec A of prime ideals of A we endow a spectral topology (in the sense of Grothendieck). We characterize irreducible closed subsets of Spec A and prove every irreducible closed subset of the space has a unique generic point.

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells
Advanced Functional Materials, EarlyView.Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Generalization of non-Hermitian spectral topology to hyperbolic lattices
Communications PhysicsHyperbolic lattices, a compelling platform for exploring matter in non-Euclidean space, challenge conventional band theory by invalidating Bloch’s theorem, necessitating the reexamination of fundamental concepts such as determining spectra in the ...

Spectral Riemann sheet topology of gapped non-Hermitian systems
SciPost PhysicsWe show topological configurations of the complex-valued spectra in gapped non-Hermitian systems. These arise when the distinctive EPs in the energy Riemann sheets of such models are annihilated after threading them across the boundary of the Brillouin ...

Spectral flow of exterior Landau-Robin hamiltonians
, 2017 We study the spectral flow of Landau-Robin hamiltonians in the exterior of a compact domain with smooth boundary. This provides a method to study the spectrum of the exterior Landau-Robin hamiltonian's dependence on the choice of Robin data, even ...
