The magneto-quantum and quantum interference effects in a two-dimensional gas of p-type charge carriers are studied for three quantum wells made of practically pure germanium in a Si0.6Ge0.4/Si0.2Ge0.8/Si0.6Ge0.4 heterostructure. The quantum well wid

The distribution of zeros and poles of best rational approximants is well understood for the functions 𝑓(𝑥)=|𝑥|𝛼, 𝛼>0. If 𝑓∈𝐶[−1,1] is not holomorphic on [−1,1], the distribution of the zeros of best rational approximants i

Let K be a quasidisk on the complex plane. We construct a sequence of monic polynomials $$p_n=p_n(\cdot ,K)$$ with all their zeros on K such that $$\Vert p_n\Vert _K\le O(1)\text{ cap }(K)^n$$ as $$n\rightarrow \infty $$.

The energy band structure of a LiNaSO4 has been calculated within the framework of density functional theory for space group P31c. It has been established that bandgap width Eg in the GGA approximation is 5.49 eV. The valence band top is generally fo
