Effect of Position-dependent Mass on Dynamical Breaking of Type B and Type X_2 N-fold Supersymmetry
N-fold supersymmetry Position-dependent mass Dynamical symmetry breaking Quasisolvability Exceptional orthogonal polynomials
2012/4/23
We investigate effect of position-dependent mass profiles on dynamical breaking of N-fold supersymmetry in several type B and type X_2 models. We find that N-fold supersymmetry in rational potentials ...
Saari's homographic conjecture for planar equal-mass three-body problem under a strong force potential
Saari's homographic conjecture planar equal-mass three-body problem Mathematical Physics
2011/9/1
Abstract: Donald Saari conjectured that the $N$-body motion with constant configurational measure is a motion with fixed shape. Here, the configurational measure $\mu$ is a scale invariant product of ...
A highly efficient measure of mass segregation in star clusters
Methods numerical star clusters mass segregation

Abstract: Investigations of mass segregation are of vital interest for the understanding of the formation and dynamical evolution of stellar systems on a wide range of spatial scales. Our method is ba...
Inverse problems for Jacobi operators II: Mass perturbations of semi-infinite mass-spring systems
Infinite mass-spring system Jacobi matrices Two-spectra inverse problem
2011/7/26
Abstract: We consider an inverse spectral problem for infinite linear mass-spring systems with different configurations obtained by changing the first mass. We give results on the reconstruction of th...
Effective-mass Klein-Gordon Equation for non-PT/non-Hermitian Generalized Morse Potential
Effective-mass Klein-Gordon Equation non-PT/non-Hermitian Generalized Morse Potential
2010/11/4
The one-dimensional effective-mass Klein-Gordon equation for the real, and non-\textrm{PT}-symmetric/non-Hermitian generalized Morse potential is solved by taking a series expansion for the wave funct...

Spinors and Positive Mass
Spinors Positive Mass
2010/4/15
As an example of how spinor methods can be applied to the positive-mass theorem, a simple, spinor-based proof of the theorem is presented for the case of a single black hole. Generalisations of the th...
We studied the static mass-radius relation of white dwarf stars with masses greater than 0.45 M\odot. We assumed pure degenerate helium interiors at a finite temperature with luminosity-mass ratio due...
