Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Exact solution of the two-axis countertwisting Hamiltonian for the half-integer $J$ case
, 2016 Bethe ansatz solutions of the two-axis countertwisting Hamiltonian for any (integer and half-integer) $J$ are derived based on the Jordan-Schwinger (differential) boson realization of the $SU(2)$ algebra after desired Euler rotations, where $J$ is the ...

Integer solutions to decomposable form inequalities
Journal of Number Theory, 2005 Let \(k\) be an algebraic number field, \(S\) a finite set of places of \(k\) containing the infinite ones and \(\mathcal O_S\) the ring of \(S\)-integers of \(k\). For any place \(v\) let \(\| \cdot\| _v\) denote the normalized \(v\)-adic absolute value, and for \(\mathbf x = (x_1, \dots, x_m) \in k^m\) define the \(S\)-height by \(H_S (\mathbf x ...

An Improved Tight Closure Algorithm for Integer Octagonal Constraints
, 2007 Integer octagonal constraints (a.k.a. ``Unit Two Variables Per Inequality'' or ``UTVPI integer constraints'') constitute an interesting class of constraints for the representation and solution of integer problems in the fields of constraint programming ...

Forced oscillations of a body attached to a viscoelastic rod of fractional derivative type
, 2012 We study forced oscillations of a rod with a body attached to its free end so that the motion of a system is described by two sets of equations, one of integer and the other of the fractional order.

Advanced Materials Interfaces, EarlyView.Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

THE RAY-METHOD: THEORETICAL BACKGROUND AND COMPUTATIONAL RESULTS
Croatian Operational Research Review, 2012 In our talk we present an algorithm for determining initial bound for the Branch and Bound (B&B) method. The idea of the algorithm is based on the use of the "ray" introduced in the "ray-method" developed for solving integer programming problems [13 ...

Integer solutions of by2 + pn = x3
Journal of Number Theory, 1975 AbstractThe equation by2 + pn = x3 is regarded as a diophantine equation in the integer variables x, y, and n. Solutions of such equations are explicitly constructed for a large class of parameters b and p. For example, the five families of solutions to the equation y2 + 11n = x3 are given. Indeed, the conditions on b and p and the proofs can be viewed
