In 1931 Dirac [1] introduced a magnetic monopole into the quantum mechanics and found a quantization relation between an electric charge e and magnetic charge q, 2μ = n, n ∈ Z, where μ = eq, and ~ =… (More)

The relationship is established between quantum phase transitions and complex geometric phases for open quantum systems governed by a non-Hermitian effective Hamiltonian with accidental crossing of… (More)

We consider the dependence of the electron transfer in photosynthetic complexes on correlation properties of random fluctuations of the protein environment. The electron subsystem is modeled by a… (More)

We perform a theoretical study of the dynamics of the electric field excitations in a microtubule by taking into consideration the realistic cylindrical geometry, dipole-dipole interactions of the… (More)

During the last few decades, nonassociative structures have been employed in various fields of modern physics. Among others, one may mention the rise of nonassociative objects such as 3-cocycles,… (More)

Gennady P. Berman, T-4; Alan R. Bishop, PADSTE; Alexander I. Nesterov, Universidad de Guadalajara Nature has evolved photosynthetic organisms to be extremely complex bio-engines that capture visible… (More)

The Dirac monopole problem is studied in details within the framework of infinite-dimensional representations of the rotation group, and a consistent pointlike monopole theory with an arbitrary… (More)
