A note on normal ordering of degenerate integral powers of number operator [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
This study derives the normal ordering expansion of degenerate integral powers of the number operator, (a†a)_{n,λ}, using recurrence relations for the coefficients and an operator action on number states. Here a† and a are respectively the boson creation

Combined sensitivity of JUNO and KM3NeT/ORCA to the neutrino mass ordering

open access: yesJournal of High Energy Physics, 2022
This article presents the potential of a combined analysis of the JUNO and KM3NeT/ORCA experiments to determine the neutrino mass ordering. This combination is particularly interesting as it significantly boosts the potential of either detector, beyond ...

Continuous review inventory model with lost sale reduction and ordering cost dependent on lead time for the mixtures of distributions [PDF]

open access: yesYugoslav Journal of Operations Research, 2021
We consider a continuous review inventory system for inventory model involving lost sales reduction through capital investment cost function and the reduction of lead time further which reduces the ordering cost.

SN1987A and neutrino non-radiative decay

open access: yesPhysics Letters B, 2023
We investigate neutrino non-radiative two-body decay in vacuum, in relation to SN1987A. In a full 3ν decay framework, we perform a detailed likelihood analysis of the 24 neutrino events from SN1987A observed by Kamiokande-II, IMB, and Baksan. We consider

An ordering of normal ultrafiltres [PDF]

open access: yesFundamenta Mathematicae, 1985
Summary: Suppose \(\kappa\) is supercompact, and \(\lambda\geq \kappa\). Let \(Nuf_{\kappa}(\lambda)\) be the collection of all normal ultrafilters on \(P_{\kappa}(\lambda)\). For any \(U\in Nuf_{\kappa}(\lambda)\), let \(i_ u\) be the elementary embedding associated with U. Def.

Determining the neutrino mass ordering and oscillation parameters with KM3NeT/ORCA

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
The next generation of water Cherenkov neutrino telescopes in the Mediterranean Sea are under construction offshore France (KM3NeT/ORCA) and Sicily (KM3NeT/ARCA).

Higher order normal modes

open access: yesJournal of Geometric Mechanics, 2020
Normal modes are intimately related to the quadratic approximation of a potential at its hyperbolic equilibria. Here we extend the notion to the case where the Taylor expansion for the potential at a critical point starts with higher order terms, and show that such an extension shares some of the properties of standard normal modes.

Deformed Bosons: Combinatorics of Normal Ordering [PDF]

open access: yesCzechoslovak Journal of Physics, 2004
We solve the normal ordering problem for (A* A)^n where A* (resp. A) are one mode deformed bosonic creation (resp. annihilation) operators satisfying [A,A*]=[N+1]-[N]. The solution generalizes results known for canonical and q-bosons. It involves combinatorial polynomials in the number operator N for which the generating functions and explicit ...

Normal ordering and non(anti)commutativity in open super strings [PDF]

open access: yes, 2007
Nonanticommutativity in an open super string moving in the presence of a background antisymmetric tensor field $\mathcal{B}_{\mu \nu}$ is investigated in a conformal field theoretic approach, leading to nonanticommutative structures.

Normal tree orders for infinite graphs [PDF]

open access: yesTransactions of the American Mathematical Society, 1994
The authors call an order-theoretic tree \(T\) on a set \(V\) normal for the graph \(G\) if \(V= V(G)\) and adjacent vertices of \(G\) are comparable in \(T\). They investigate the existence of so-called linked and well-linked normal trees for \(G\); for well-linked \(T\) the maximal chains of \(T\) are well ordered and induce connected subgraphs ...
