Recent experiments on quantum walks (QWs) of a single and two particles demonstrated subtle statistics-dependent in one-dimensional (1D) lattices. However the roles interaction statistics such kind are little known at many-body level. In this letter, using time-evolving block decimation algorithm perturbation theory we rigorously study QWs, Bloch oscillations Fisher informations (FIs) for three...

Let $t>0$ be a real number and $G$ graph. We say is $t$-tough if for every cutset $S$ of $G$, the ratio $|S|$ to components $G-S$ at least $t$. Determining toughness an NP-hard problem arbitrary graphs. The Toughness Conjecture Chv\'atal, stating that there exists constant $t_0$ such $t_0$-tough graph with three vertices hamiltonian, still open in general. A called $(P_2\cup P_3)$-free it do...

We performed $^{59}$Co nuclear magnetic and quadrupole resonance (NMR NQR) measurements under pressure on a single-crystalline CeCoSi, which undergoes an unresolved phase transition at $T_0$. The NQR spectra clearly showed that the $T_0$ is nonmagnetic, but any symmetry lowering Co site was not seen irrespective of feature second-order transition. By contrast, NMR were split by induced field pe...

Let Λ $\Lambda$ be a hereditary algebra, B 0 = End ( T ) $B_0=\operatorname{End}_\Lambda (T_0)$ tilted algebra. We will construct tilting $B_0$ -modules from and use this result to show how quivers of BB-tilted algebras can obtained those .

Let $R$ be a commutative ring with identity and $M$ be an$R$-module. Let $FSpec(M)$ denotes the collection of all prime fuzzysubmodules of $M$. In this regards some basic properties of Zariskitopology on $FSpec(M)$ are investigated. In particular, we provesome equivalent conditions for irreducible subsets of thistopological space and it is shown under certain conditions$FSpec(M)$ is a $T_0-$spa...

the hydrogen abstraction reaction by oh radical from ch2brch2br (r1) and ch₃chbr2 (r2) is investigated theoretically by semi-classical transition state theory. the stationary points for both reactions are located by using ωb97x-d and kmlyp density functional methods along with cc-pvtz basis. single-point energy calculations are performed at the qcisd(t) and ccsd(t) levels of theory with differe...
