Giant anomalous Josephson effect as a probe of spin texture in topological insulators
Niklas Hüttner, Andreas Costa, Leandro Tosi +9
Surface states of topological insulators feature chiral spin-momentum locking. When such states are used as weak link between two superconductors, their spin texture gives rise to…
Lipschitz geometry and combinatorics of circular snakes
André Costa, Davi Medeiros, Emanoel Souza
This paper explores the Lipschitz geometric and combinatorial properties of germs of real semialgebraic surfaces (or, more generally, definable in a polynomially bounded o-minimal…
One point compactification and Lipschitz normally embedded definable subsets
André Costa, Vincent Grandjean, Maria Michalska
A closed subset of , definable in some given o-minimal structure, is Lipschitz normally embedded in if and only if its one-point compactification is Li…
Lipschitz trivial values of polynomial mappings
André Costa, Vincent Grandjean, Maria Michalska
Real or complex polynomial mappings between affines spaces admitting a Lipschitz-trivial value are completely characterized.
Large Random Simplicial Complexes, II; the fundamental groups
A. Costa, M. Farber
In our recent work we described conditions under which a multi-parameter random simplicial complex is connected and simply connected. We showed that the Betti numbers of multi-para…
Large random simplicial complexes, I
A. Costa, M. Farber
In this paper we develop further the multi-parameter model of random simplicial complexes. Firstly, we give an intrinsic characterisation of the multi-parameter probability measure…
