Many-body perturbation theory calculations on circular quantum dots [PDF]
Physical Review B, 2007 The possibility to use perturbation theory to systematically improve calculations on circular quantum dots is investigated. A few different starting points, including Hartree-Fock, are tested and the importance of correla- tion is discussed. Quantum dots with up to 12 electrons are treated and the effects of an external magnetic field are examined. The

Short-range guiding can result in the formation of circular aggregates in myxobacteria populations. [PDF]
PLoS Computational Biology, 2015 Myxobacteria are social bacteria that upon starvation form multicellular fruiting bodies whose shape in different species can range from simple mounds to elaborate tree-like structures.

Scientific Reports, 2022 AbstractImportant properties of the dynamics of a spacecraft can be obtained from the Circular Restricted Three Body Problem and the Bi-Circular Bi-planar Four Body Problem. In this work, both systems are compared under the perspective of the costs involved in a transfer between the smaller primaries.

Wave forces on fixed vertical axisymmetric bodies
Vietnam Journal of Mechanics, 1994 In this paper, wave forces on fixed vertical axisymmetric bodies are considered by the hybrid boundary element method. A program package on Fortran IV on PC has been developed and applied for the cases of a vertical circular (large and small diameter ...

Dynamics of a System of Two Connected Bodies Moving along a Circular Orbit around the Earth [PDF]
EPJ Web of Conferences, 2020 Symbolic–numeric methods are used to investigate the dynamics of a system of two bodies connected by a spherical hinge. The system is assumed to move along a circular orbit under the action of gravitational torque. The equilibrium orientations of the two-

New exact particular analytical solutions of the triangular restricted three-body problem
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 The triangular restricted three-body problem is studied in special non-inertial central reference frame with origin at forces centre of this problem. Masses are arbitrary values. We studied the solutions of dimensionless differential equations of motion

Gravitational waves from bodies orbiting the Galactic center black hole and their detectability by LISA [PDF]
Astronomy & Astrophysics, 2019 Aims. We present the first fully relativistic study of gravitational radiation from bodies in circular equatorial orbits around the massive black hole at the Galactic center, Sgr A* and we assess the detectability of various kinds of objects by the ...

Motion of spinning particles in non asymptotically flat spacetimes
European Physical Journal C: Particles and Fields, 2020 The assumption of asymptotic flatness for isolated astrophysical bodies may be considered an approximation when one considers a cosmological context where a cosmological constant or vacuum energy is present.

Celestial mechanics of elastic bodies [PDF]
, 2006 We construct time independent configurations of two gravitating elastic bodies. These configurations either correspond to the two bodies moving in a circular orbit around their center of mass or strictly static configurations.Comment: 16 pages, 2 figures,
