Structure, Time Propagation and Dissipative Terms for Resonances

, 2008
For odd anharmonic oscillators, it is well known that complex scaling can be used to determine resonance energy eigenvalues and the corresponding eigenvectors in complex rotated space.

Some Further Insight into the Sturm–Liouville Theory

Mathematics
Some classical texts on the Sturm–Liouville equation (p(x)y′)′−q(x)y+λρ(x)y=0 are revised to highlight further properties of its solutions. Often, in the treatment of the ensuing integral equations, ρ=const is assumed (and, further, ρ=1).

Description of CuInP2S6 ferrielectrics in a mixed Ising model

Condensed Matter Physics
The appearance of spontaneous polarization in CuInP2S6 ferrielectrics is related to the second order Jahn-Teller effect for copper cations located in a double-well local potential, the stereoactivity of indium cations located in a three-well local ...

Improved thermodynamic modeling of linear triatomic molecules using a hyperbolic Pöschl-Teller oscillator

Chemical Thermodynamics and Thermal Analysis
Accurate characterization of thermodynamic properties at high temperatures is essential for modeling chemical systems. However, widely used methods such as NASA polynomials, which are based on the rigid-rotor harmonic oscillator (RRHO) approximation ...

Geometric quantum complexity of bosonic oscillator systems

Journal of High Energy Physics
According to the pioneering work of Nielsen and collaborators, the length of the minimal geodesic in a geometric realization of a suitable operator space provides a measure of the quantum complexity of an operation.
