One-dimensional Schr\"odinger operators with $\delta'$-interactions on a set of Lebesgue measure zero math.FA math.SP We give an abstract definition of a one-dimensional Schr\"odinger operator with $\delta'$-interaction on an arbitrary set~$\Gamma$ of Lebesgue measure zero. The number of negative eigenvalues ...

Robust multipartite quantum correlations without complex encodings quant-ph One of the main challenges for the manipulation and storage of multipartite entanglement is its fragility under noise. We present a simple recipe for the systematic enhancement of the resistance of multipartite entanglement against any loca...

Hausdorff dimension of three-period orbits in Birkhoff billiards math.DS nlin.CD We prove that the Hausdorff dimension of the set of three-period orbits in classical billiards is at most one. Moreover, if the set of three-period orbits has Hausdorff dimension one, then it has a tangent line at almost every point.

Symbolic approach and induction in the Heisenberg group math.DS We associate a homomorphism in the Heisenberg group to each hyperbolic unimodular automorphism of the free group on two generators. We show that the first return-time of some flows in "good" sections, are conjugate to niltranslations, which have the pr...

Continuation and collapse of homoclinic tangles math.DS math.NA By a classical theorem transversal homoclinic points of maps lead to shift dynamics on a maximal invariant set, also referred to as a homoclinic tangle. In this paper we study the fate of homoclinic tangles in parameterized systems from the viewpoint o...

On the vacua of N = 8 gauged supergravity in 4 dimensions hep-th We discuss a simple procedure for finding vacua of gauged supergravity models, based on the variation of the embedding tensor rather than on a direct minimization of the scalar potential. We apply this procedure to N=8 gauged supergravity in 4 dimensi...
