For real inverse temperature beta, the canonical partition function is always positive, being a sum of positive terms. There are zeros, however, on the complex beta plane that are called Fisher zeros. In the thermodynamic limit, the Fisher zeros coal

We show that one can obtain analytic solutions of the time-dependent Schrodinger equation that are more complex than the well-known oscillating coherent wave packet. Such Hermite-Gaussian or initially square wave packets exist for a free particle or

The generalized Crank-Nicolson method is employed to obtain numerical solutions of the two-dimensional time-dependent Schrodinger equation. An adapted alternating-direction implicit method is used, along with a high-order finite difference scheme in

We consider accurate numerical solutions of the one-dimensional time-dependent Schrödinger equation when the potential is piecewise continuous. Spatial step sizes are defined for each of the regions between the discontinuities and a matching conditi

We consider an ideal Bose gas contained in a cylinder in three spatial dimensions, subjected to a uniform gravitational field. It has been claimed by some authors that there is discrepancy between the semi-classical and quantum calculations in the th

We consider the $P$- and $Q$-shape parameters in the eigenphase and `bar' phase shift representations for the two Reid potentials and the more recent Moscow potential. The values of these parameters were obtained from integrals of the zero-energy wav

The radius of the bound state of a particle obeying the Dirac equation with a separable interaction is compared to the radius of the bound state of the particle obeying the Schrodinger equation with a phase equivalent separable potential. By appropri

We investigate scattering in a one-dimensional two-channel system using a model that is analytically tractable. We find anomalously large time advance over a small energy range of the transmission in the incident channel. This time advance for transm

We show that for S-wave scattering at an energy ${\mathit{k}}^{2}$ by a local potential which supports no more than one bound state, the shape parameter P and coefficients of higher powers of ${\mathit{k}}^{2}$ in the effective range expansion functi

The $\stackrel{-}{K}N$ inverse scattering problem is solved for a model which assumes that the $\ensuremath{\Lambda}(1405)$ is an elementary particle rather than a virtual bound state of the $\stackrel{-}{K}N$ system. This model points to a consisten
