Segregation of P and S Impurities to A Σ9 Grain Boundary in Cu
Metals, 2020 The segregation of P and S to grain boundaries (GBs) in fcc Cu has implications in diverse physical-chemical properties of the material and this can be of particular high relevance when the material is employed in high performance applications.

Visualization of the disordered structure of Fe-Ni Invar alloys by reverse monte carlo calculations
Frontiers in Materials, 2022 Reverse Monte Carlo (RMC) calculation was performed to visualize the atomic arrangement in a disordered Fe55Ni45 alloy, which is classified as an intermediate structure between the non-crystalline glass and crystalline structures. The optimized structure

Nuclear ground-state properties from mean-field calculations [PDF]
, 2002 The volume and surface effects in the nuclear local energy density and the volume and surface components of the pairing interaction are discussed in the context of the mean-field, Hartree-Fock-Bogoliubov description of atomic nuclei.

Superconducting transition temperatures of the elements related to elastic constants [PDF]
, 2004 For a given crystal structure, say body-centred-cubic, the many-body Hamiltonian in which nuclear and electron motions are to be treated from the outset on the same footing, has parameters, for the elements, which can be classified as (i) atomic mass M, (

Study of dimensional dependencies of thermodynamic characteristics of nanoparticles
Қарағанды университетінің хабаршысы. Физика сериясы, 2019 In the article some approaches to the theoretical description of the deviations of thermodynamic characteristics, such as the heat capacity and the Debye temperature for nanoparticles are considered. The standard Debye inference for the heat capacity of

Anomalous atomic volume of α-Pu [PDF]
Physical Review B, 1997 We have performed full charge-density calculations for the equilibrium atomic volumes of the {alpha}-phase light actinide metals using the local density approximation (LDA) and the generalized gradient approximation (GGA). The average deviation between the experimental and the GGA atomic radii is 1.3{percent}.

Atomic Stress State Inside fcc and bcc Random Alloys: A First-Principles Approach
Frontiers in Materials, 2022 The stress state at an atomic level and its governing physics inside a random alloy are essential elements in developing a model for solid solution strengthening in random alloys, which is one of the primary strengthening mechanisms of high-entropy ...

An optically pumped atomic clock based on a continuous slow cesium beam
Frontiers in Physics, 2022 Herein, we report the scheme of an optically pumped atomic clock based on a cold cesium atomic beam source. We propose the laser system and physical mechanism of this atomic clock, wherein the atomic beam travels in an upper parabolic trajectory, thereby

LOCAL DISTORTIONS AND VOLUME CHANGES IN SEMICONDUCTORS - DONORS IN SILICON [PDF]
, 2002 Experiments giving impurity-induced lattice distortion can measure quite distinct quantities. In particular EXAFS (extended X-ray fine structure) measures nearest-neighbour distances, whereas both volume changes and recent spectroscopic data measure long-
