Az Országgyűlés 2021. június 15. napján fogadta el a polgári peres eljárás elhúzódásával kapcsolatos vagyoni elégtétel érvényesítéséről szóló évi XCIV. törvényt (továbbiakban: Pevtv.), amely 2022. január 1. lépett hatályba. A jogszabállyal együtt született új jogintézmény, pedig nemcsak eljárásjog szempontjából kiemelt jelentőségű, hanem annak emberi jogi és alkotmányjogi vonatkozásai miatt, va...

We derive an analytical lower bound for the concurrence of a bipartite quantum state in arbitrary dimension. A functional relation is established relating concurrence, the Peres-Horodecki criterion, and the realignment criterion. We demonstrate that our bound is exact for some mixed quantum states. The significance of our method is illustrated by giving a quantitative evaluation of entanglement...

Tomographic analysis demonstrates that the polarization state of pairs of photons emitted from a biexciton decay cascade becomes entangled when spectral filtering is applied. The measured density matrix of the photon pair satisfies the Peres criterion for entanglement by more than 3 standard deviations of the experimental uncertainty and violates Bell's inequality. We show that the spectral fil...

Consider the time Toz when the random walk on a weighted graph started at the vertex o first hits the vertex set z. We present lower bounds for Toz in terms of the volume of z and the graph distance between o and z. The bounds are for expected value and large deviations, and are asymptotically sharp. We deduce rate of escape results for random walks on infinite graphs of exponential or polynomi...

We study the orthogonal projections of a large class of self-affine carpets, which contains the carpets of Bedford and McMullen as special cases. Our main result is that if Λ is such a carpet, and certain natural irrationality conditions hold, then every orthogonal projection of Λ in a non-principal direction has Hausdorff dimension min(γ, 1), where γ is the Hausdorff dimension of Λ. This gener...
