Helix untwisting and bubble formation in circular DNA [PDF]

open access: yesJ. Chem. Phys. Vol.138, 205103 (2013), 2013
The base pair fluctuations and helix untwisting are examined for a circular molecule. A realistic mesoscopic model including twisting degrees of freedom and bending of the molecular axis is proposed. The computational method, based on path integral techniques, simulates a distribution of topoisomers with various twist numbers and finds the ...

Limits to Freedom of Speech in the Republic of Latvia During the Parliamentary Period (1918–1934)

open access: yesLaw: Journal of the University of Latvia, 2021
The article is dedicated to the analysis of one element of the constitutional identity of the Latvian State – freedom of speech – during the initial democratic period in the State’s existence.

Composite Spin Liquid in Correlated Topological Insulator - Spin Liquid without Spin-Charge Separation [PDF]

open access: yes, 2012
In this paper, we found a new type of insulator - composite spin liquid which can be regarded as a short range B-type topological spin-density-wave. Composite spin liquid is topological ordered state beyond the classification of traditional spin liquid states. The elementary excitations are the "composite electrons" with both spin degree of freedom and

The Black Hole Interior in Quantum Gravity [PDF]

open access: yesPhys. Rev. Lett. 114, 201301 (2015), 2014
We discuss the interior of a black hole in quantum gravity, in which black holes form and evaporate unitarily. The interior spacetime appears in the sense of complementarity because of special features revealed by the microscopic degrees of freedom when viewed from a semiclassical standpoint.

On the Existence of Localized Excitations in Nonlinear Hamiltonian Lattices [PDF]

open access: yes, 1994
We consider time-periodic nonlinear localized excitations (NLEs) on one-dimensional translationally invariant Hamiltonian lattices with arbitrary finite interaction range and arbitrary finite number of degrees of freedom per unit cell. We analyse a mapping of the Fourier coefficients of the NLE solution.

Generalized Pseudo-SU(3) Model and Pairing [PDF]

open access: yes, 1994
The pseudo-SU(3) model is extended to explicitly include the spin and proton-neutron degrees of freedom. A general formalism for evaluating matrix elements of one-body and two-body tensor operators within this framework is presented. The pairing interaction, which couples different irreducible representations of SU(3), is expressed in terms of pseudo ...

The autoparametric 3:2 resonance in conservative systems [PDF]

open access: yes, 2005
In the resonance model, high-frequency quasi-periodic oscillations (QPOs) are supposed to be a consequence of nonlinear resonance between modes of oscillations occurring within the innermost parts of an accretion disk. Several models with a prescribed mode--mode interaction were proposed in order to explain the characteristic properties of the ...

Cluster states in nuclei as representations of a U(n+1) group [PDF]

open access: yesPhys.Rev. C61 (2000) 067305, 2000
We propose a description of cluster states in nuclei in terms of representations of unitary algebras U(n+1), where n is the number of space degrees of freedom. Within this framework, a variety of situations including both vibrational and rotational spectra, soft and rigid configurations, identical and non-identical constituents can be described.
