We review the status of several phenomenological topics of current interest in neutrino oscillations: (i) Solar neutrino oscillations after the first Sudbury Neutrino Observatory measurements, including both model-independent and model-dependent results; (ii) Dominant νμ → ντ oscillations of atmospheric and K2K neutrinos, and possible subdominant oscillations induced by either extra states or e...

Tuzak çeşitlerinin etkinliği; araştırma yöntemi, örnekleme, popülasyon yoğunluğu, mevsimsel dağılış gibi hususlarda böceklerin izlenmesi ve değerlendirilmesi için önemlidir. Bu çalışma ile Bolkar Dağlarında farklı yakalama yöntemleri kullanılarak yakalanan Acmaeoderini böcek türlerinin tuzak karşılaştırılması bu türlerin dağılışları değerlendirilmiştir. Çalışma alanında tribusuna ait toplam 815...

Ultralight scalars could extract energy and angular momentum from a Kerr black hole (BH) because of superradiant instability. Multiple modes labelled with $nlm$ grow while rotating around the BH, emitting continuous gravitational wave (GW). In this work, we carefully study contribution subdominant $n\geq 1$ in evolution BH-condensate system. We find BH still evolves along Regge trajectory $n=0$...

ABSTRACT Eccentricity and spin precession are key observables in gravitational-wave astronomy, encoding precious information about the astrophysical formation of compact binaries together with fine details relativistic two-body problem. However, two effects can mimic each other emitted signals, raising issues around their distinguishability. Since inferring existence both eccentricity simultane...

The Kitaev interaction in a honeycomb lattice with higher-spin $S$ has been one of the central attractions, as it may offer quantum spin liquids. A microscopic theory showed that when Hund's coupling at transition metal generates $S>\frac{1}{2}$, spin-orbit heavy ligands provides route to interaction. However, there have debates over its strength compared other symmetry-allowed interactions....

For any stochastic matrix A of order n, denote its eigenvalues as λ1(A), . . . , λn(A), ordered so that 1 = |λ1(A)| ≥ |λ2(A)| ≥ . . . ≥ |λn(A)|. Let cT be a row vector of order n whose entries are nonnegative numbers that sum to n. Define S(c), to be the set of n × n row-stochastic matrices with column sum vector cT . In this paper the quantity λ(c) = max{|λ2(A)||A ∈ S(c)} is considered. The ve...

Assuming atmospheric neutrino oscillations with dominant $ transitions , we discuss how subdominant e mixing (within the Chooz reactor bounds) can alter the zenith distributions of neutrino-induced electrons and muons. We isolate two peculiar distortion eeects, one mainly related to e mixing in vacuum and the other to matter oscillations, that may be suu-ciently large to be detected by the Supe...

We develop majorisation results that characterise changes in eigenvector components of a graph’s adjacency matrix when its topology is changed. Specifically, for general (weighted, directed) graphs, we characterise changes in dominant eigenvector components for singleand multi-row incrementations. We also show that topology changes can be tailored to set ratios between the components of the dom...
