- Microcanonical thermodynamic properties of helium nanodroplets. Lehmann, Kevin K. // Journal of Chemical Physics;8/8/2003, Vol. 119 Issue 6, p3336
The density of states and other thermodynamic functions of helium nanodroplets are calculated for a microcanonical ensemble with both energy and total angular momentum treated as conserved quantum numbers. These functions allow angular momentum conserving evaporative cooling simulations. As part...

The article presents a study on the peculiarities of unguided reentry of space transportation system parts. It notes the analytical solution and conjugate sets of equations as well as the qualitative analysis of the nonequilibrium trajectory motion. The study found that the phenomenon suggests...

We propose a double-pass method of exact diagonalization of a finite cluster on the base of functions that have a definite total spin and transform by a definite irreducible representation of the point symmetry group of the lattice. We also propose the method for approximating the energy...

The total energy E of a star as a function of its angular momentum J and mass M in the Newtonian theory, E = E(J, M) [in general relativity, the gravitational mass of a star as a function of its angular momentum J and rest mass m, M = M(J, m)], is used to determine the remaining parameters...

- Unimolecular decomposition in a spherically symmetric potential. Klots, Cornelius E. // Journal of Chemical Physics;1/15/1993, Vol. 98 Issue 2, p1110
Unimolecular decompositions are considered where the interaction between the separating fragments can be described by a function solely of their radial separation. It is shown how previous treatments, confined to idealized models, can be generalized. Kinetic energy distributions and rate...

- Geometrothermodynamics of Myers-Perry Black Holes. Bravetti, Alessandro; Momeni, Davood; Myrzakulov, Ratbay; Altaibayeva, Aziza // Advances in High Energy Physics;2013, p1
We consider the thermodynamics and geometro thermodynamics of the Myers-Perry black holes in five dimensions for three different cases, depending on the values of the angular momenta. We follow Davies approach to study the thermodynamics of black holes and find a nontrivial thermodynamic...

The idea of 'frozen-in' magnetic field lines for ideal plasmas is useful to explain diverse astrophysical phenomena, for example the shedding of excess angular momentum from protostars by twisting of field lines frozen into the interstellar medium. Frozen-in field lines, however, preclude the...

Communications using the orbital angular momentum (OAM) of radio waves have attracted much attention in recent years. In this paper, a novel millimeter-wave dual OAM mode antenna is cleverly designed, using which a 60 GHz wireless communication link with two separate OAM channels is...
