Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures
Advanced Materials, EarlyView.Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

On the Dispersions of the Polynomial Maps over Finite Fields [PDF]
The Electronic Journal of Combinatorics, 2008 We investigate the distributions of the different possible values of polynomial maps ${\Bbb F}_q^n\longrightarrow{\Bbb F}_q$, $x\longmapsto P(x)$. In particular, we are interested in the distribution of their zeros, which are somehow dispersed over the whole domain ${\Bbb F}_q^n$.

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping
Advanced Materials, EarlyView.Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...

Further study on permutation polynomials over finite fields
四川大学学报. 自然科学版, 2019 Permutation polynomials over finite fields becomes an interesting subject. To constructing new classes permutation polynomials is an open problem raised by Lidl and Mullen in 1988.

Evaluation of Some Sums of Polynomials in Fq[t]
Journal of Applied Mathematics, 2019 We prove the polynomial analogues of some Liouville identities from elementary number theory. Consequently several sums defined over the finite fields Fq[t] are evaluated by combining the results obtained and some of the results from sums of reciprocals ...

On flux integrals for generalized Melvin solution related to simple finite-dimensional Lie algebra
European Physical Journal C: Particles and Fields, 2017 A generalized Melvin solution for an arbitrary simple finite-dimensional Lie algebra $$\mathcal G$$ G is considered. The solution contains a metric, n Abelian 2-forms and n scalar fields, where n is the rank of $$\mathcal G$$ G .

Subquadratic-time factoring of polynomials over finite fields
Symposium on the Theory of Computing, 1995 New probabilistic algorithms are presented for factoring univariate polynomials over finite fields. The algorithms factor a polynomial of degree n over a finite field of constant cardinality in time O(n 1.815 ).

Functional graphs of polynomials over finite fields
Journal of Combinatorial Theory, Series B, 2016 Given a function $f$ in a finite field ${\mathbb F}_q$ of $q$ elements, we define the functional graph of $f$ as a directed graph on $q$ nodes labelled by the elements of ${\mathbb F}_q$ where there is an edge from $u$ to $v$ if and only if $f(u) = v$.

Factorization of Polynomials over Finite Fields and Characteristic Sequences [PDF]
, 1993 A new factorization algorithm for polynomials over finite fields was recently developed by the first author. For finite fields of characteristic 2, it is known from previous work that this algorithm has several advantages over the classical Berlekamp ...
