Feynman path integrals for the inverse quartic oscillator
S. Mazzucchi The Feynman path integral representation for the weak solution of the Schrodinger equation with an inverse quartic oscillator potential is given in terms of a well defined infinite dimensional oscillatory integral. An analytically continued Wiener integral representation for the solution is provided ... [J. Math. Phys. 49, 093502 (2008)] published Thu Sep 4, 2008.
The transmission property of the discrete Heisenberg ferromagnetic spin chain
Qing Ding and Wei Lin We present a mechanism for displaying the transmission property of the discrete Heisenberg ferromagnetic (DHF) spin chain via a geometric approach. With the aid of a discrete nonlinear Schrodinger-like equation which is the discrete gauge equivalent to the DHF, we show that the determination of tran ... [J. Math. Phys. 49, 093501 (2008)] published Thu Sep 4, 2008.
The flip-over effect in self-similar laser-induced plasma expansion
Nathan P. Baxter and Sergei V. Shabanov We present a rigorous study of a dynamical model for a nonsymmetric expansion of laser-induced plasma plumes into the vacuum. The model is used in the laser film deposition technique and for remote chemical analysis in the so-called laser-induced breakdown spectroscopy. It defines a particular class ... [J. Math. Phys. 49, 093101 (2008)] published Wed Sep 3, 2008.
