The ground-state properties of two-dimensional liquid 4 He at zero temperature are studied by means of a quadratic diffusion Monte Carlo method. As interatomic potential we use a revised version of the HFDHE2 Aziz potential which is expected to give a better description of the interaction between helium atoms. The equation of state is determined with great accuracy over a wide range of densitie...

This paper aims to develop an integrated analytical framework for revolution, reform, and involution under dictatorship based on China’s history. In order to grasp the essence of political and economic interactions in historic China, this paper gets some abstract variables from China’s history, on the basis of which a political economy model is built. The autocrat plays an important role in det...

The structure of multiply quantized or giant vortex states in atomic Fermi gases across a Feshbach resonance is studied within the context of self-consistent Bogoliubov–de Gennes theory. The particle density profile of vortices with 1 flux quanta is calculated. Owing to discrete branches of vortex-core bound states, inside the core the density oscillates as a function of the distance from the v...

We have carried out a preliminary analysis of shot noise at hopping, focusing on uniform one-dimensional ~1D! arrays of sites separated by N tunnel barriers. The results show that at low temperatures the low-frequency density of the shot noise varies from 1/N to 1 of the Schottky value, depending on the geometry, electron density, and Coulomb interaction strength. An interesting feature is v de...

We study the one-dimensional Bose gas in spatially correlated disorder at zero temperature, using an extended density-phase Bogoliubov method. We analyze, in particular, the decay of the one-body density matrix and the behavior of the Bogoliubov excitations across the phase boundary. We observe that the transition to the Bose-glass phase is marked by a power-law divergence of the density of sta...

The study focuses on exploring the changes in hyperon-baryon interaction at various nuclear densities. This approach starts by building a vacuum hyperon-nucleon model based Boson -Exchange maintaining SU(3) flavor symmetry. Bethe-Goldstone equation is then explored to investigate medium properties over bare interaction. A detailed investigation of density dependence revealed clear low energy pa...

Background:  In this study a series of basic dosimetric properties of a low-density (LD) gel dosimeter are investigated. The dose response is studied regarding to linearity, sensitivity, dose-rate and energy dependence as well as lung tissue equivalence. Materials and Methods: The LD gel was made by mixing the polymer gel with expanded polystyrene spheres. Energy dependence was studied...

We study theoretically the Raman spectrum of the rotated double-layer graphene, consisting of two graphene layers rotated with respect to each other by an arbitrary angle θ . We find a relatively simple dependence of the Raman G peak intensity on the angle θ . On the other hand, the Raman 2D peak position, intensity, and width show a much more complicated dependence on the angle θ . We account ...
