Lý thuyết hàm chức năng mật độ hạt nhân Dịch bởi AI
Pleiades Publishing Ltd - Tập 41 - Trang 868-873 - 2010
M. Stoitsov
Sự hiểu biết về các hạt nhân nguyên tử là rất quan trọng cho một lý thuyết hạt nhân hoàn chỉnh, cho vật lý hạt nhân thiên văn, cho việc thực hiện các nhiệm vụ thí nghiệm mới, và cho nhiều ứng dụng khác nhau. Trong khuôn khổ lý thuyết hàm chức năng mật độ, năng lượng liên kết tổng cộng của hạt nhân được biểu thị bởi một hàm chức năng của các ma trận mật độ hạt nhân và các đạo hàm của chúng. Sự biến...... hiện toàn bộ

Neutrino radiative decay in external field and medium
Pleiades Publishing Ltd - Tập 45 - Trang 397-408 - 2014
A. I. Ternov, P. A. Eminov
The current state of the theory of massive neutrino radiative decay is reviewed. By extending our previous studies, we thoroughly analyze the process of radiative decay of a massive Dirac neutrino in the strong external magnetic field H ≫ H 0 = m 2 c ...... hiện toàn bộ
Modeling type Ia supernovae and quark novae
Pleiades Publishing Ltd - Tập 46 - Trang 808-811 - 2015
F. K. Röpke
Compact astrophysical objects can change their structure and composition in combustion-like processes. In the case of white dwarfs, thermonuclear burning can even lead to an explosion as a Type la supernova. We give a brief account of the physical concepts of combustion and of methods to model this phenomenon in large-scale numerical simulations. As examples for application we discuss thermonuclea...... hiện toàn bộ
Search for νμ → ντ oscillations in appearance mode in the OPERA experiment
Pleiades Publishing Ltd - Tập 42 - Trang 553-557 - 2011
Yu. A. Gornushkin
The OPERA experiment at the underground Gran Sasso Laboratory (LNGS) has to perform the first detection of neutrino oscillations in appearance mode through the direct observation of νμ → ντ. The apparatus consists of a lead/emulsion-film target complemented by electronic detectors. It is placed in the high-energy, long-baseline CERN neutrino beam (CNGS) 730 km away from the neutrino source. Runs w...... hiện toàn bộ
Moduli matrices of the vacua and walls on SO(2N)/U(N)
Pleiades Publishing Ltd - Tập 43 - Trang 652-653 - 2012
M. Arai, Su. Shin
We construct parallel domain walls on the SO(2N)/U(N) manifold by using the moduli matrices, which were originally formulated on the Grassmann manifold. We propose a method to impose a quadratic constraint to the moduli matrices. This talk is based on [3]PRD83,125003(2011). This article is prepared for the proceedings of International Workshop on Supersymmetries and Quantum Symmetries-SQS 2011.
Statistical Mechanics of Thermal Fluctuations of Nearly Spherical Membranes: the Influence of Bending and Stretching Elasticities
Pleiades Publishing Ltd - Tập 52 Số 2 - Trang 290-314 - 2021
Tonchev, N. S.
Theoretical studies of nearly spherical vesicles and microemulsion droplets, that present typical examples for thermally-excited systems that are subject to constraints, are reviewed. We consider the shape fluctuations of such systems constrained by fixed area $$A$$ and fixed volume $$V$$ , whose geometry is presented in terms of scalar spherical harmonics. These constraints can be incorporated in...... hiện toàn bộ
Relation between the Chiral Separation Effect and the Axial Anomaly in Real-Time Formalism
Pleiades Publishing Ltd - Tập 54 - Trang 948-949 - 2023
Z. V. Khaidukov
The relation between the Chiral separation effect(CSE) and the axial anomaly in point-splitting method in real time formalism(RTF) is shown. As a consequence the difference of protection mechanism of CSE and of the axial anomaly is shown.
Abelian 3-form gauge theory: Superfield approach
Pleiades Publishing Ltd - Tập 43 Số 5 - Trang 669-672 - 2012
R. P. Malik
N.N. Bogoliubov’s contribution to nonequilibrium statistical mechanics (1937–1945)
Pleiades Publishing Ltd - Tập 41 - Trang 1061-1063 - 2010
Yu. G. Rudoy
It is shown that many important and still relevant results in the field of nonequilibrium statistical mechanics were derived by Bogoliubov (jointly with N.M. Krylov) early in the prewar years and were completely published in a still insufficiently known monograph of 1945. Among these findings were the concept of time hierarchy for stochastic evolution, the concept of quasi-averages that remove sym...... hiện toàn bộ
An advanced precision analysis of the SM vacuum stability
Pleiades Publishing Ltd - Tập 48 - Trang 698-703 - 2017
A. V. Bednyakov
The talk is devoted to the problem of stability of the Standard Model vacuum. The effective potential for the Higgs field, which can potentialy exhibit additional, deeper minimum, is considered as a convenient tool for addressing the problem. Different methods and approximations used to calculate the potential are considered. Special attention is paid to the renomalization-group approach that allo...... hiện toàn bộ
