Signature inversion in semi-decoupled bands: Residual interaction between h9/2 protons and i13/2 neutrons
(Elsevier, 1997)
Semi-decoupled bands based on the πh9/2 ⊗ vi13/2 configuration are observed in 162Tm,164Tm and 174Ta. Spins assigned to these bands imply an inversion of the expected signature splitting, which is interpreted as being the ...

Comment on “Boson-realization model for the vibrational spectra of tetrahedral molecules”
(American Physical Society, 1997)
An algebraic model in terms of a local harmonic boson realization was recently proposed to study molecular vibrational spectra [Zhong-Qi Ma et al., Phys. Rev. A 53, 2173 (1996)]. Because of the local nature of the bosons ...

Steady uniform shear flow in a low density granular gas
(American Physical Society, 1997)
The steady uniform shear flow of a low density granular sytem is studied by means of a kinetic model equation and also by direct Monte Carlo simulation of the Boltzmann equation. The former can be exactly solved for arbitrary ...

Aging in the one-dimensional Ising model with Glauber dynamics
(IOP Publishing Ltd., 1997-10-01)
We study the zero-temperature limit of the one-dimensional Ising model with nearest-neighbor interactions and Glauber dynamics. An exact evolution equation is derived for the spin-spin two-time correlation functions following ...

Glassy behavior in a simple model with entropy barriers
(American Physical Society, 1997)
We study the dynamical behavior of a system with a variable number of particles n. The empty state n=0 is the ground state, while all the other states n>0 are degenerate in energy. In equilibrium, the mean number of particles ...

Accidental degeneracy in a simple quantum system: A new symmetry group for a particle in an impenetrable square-well potential
(American Association of Physics Teachers, 1997)
The two-dimensional square-well potential is one of the simplest quantum-mechanical systems that exhibits accidental degeneracy. We show that the double degeneracy present is a consequence of a dynamical symmetry and ...
