Supersymmetry and Double-Well Potentials
Physical Review Letters, 1988The ideas of supersymmetric quantum mechanics are applied to the tunneling problem for double-well potentials. We evaluate the tunneling by developing a systematic perturbation expansion whose leading term is an improvement over the standard WKB result. We find that the perturbation series converges rapidly.

Abstract A new method of calculating betatron field parameters is described. Using a medel betatron field, the effective radial potential well, orbit radius, and ratio of central field to orbit field are obtained. It is shown that potential wells of sufficient depth for electron injection into plasma betatrons can be achieved without difficulty.

We measures and investigate the correlation between well potential and SEUs to effectively detect SEUs by well potential perturbation. Cell-based perturbation detectors are implemented adjacent to FFs constructed a shift register. They measures the locations of voltage levels over 0.6 or 0.8 V.

Investigating the Stickiness in a Potential Well
International Journal of Bifurcation and ChaosIn this work, we use the finite-time Lyapunov exponent (FTLE) for a version of the potential well model with an oscillating bottom. This model is described by a conservative two-dimensional mapping that exhibits a mixed phase space, namely it contains a sea of chaos and the regions of stability.

The problem of potential wells can be described as follows. Consider the minimization problem $$ (P)inf\left\{ {\int_\Omega {f(Du(x))dx:u \in \varphi + W_0^{1,p}(\Omega ;{\mathbb{R}^n})} } \right\}, $$ , Where \( \Omega \subset {\mathbb{R}^n} \) is a bounded open set \( \varphi \in {W^{1,p}}\left( {\Omega ;{\mathbb{R}^n}} \right) \) is a given ...

Regge trajectories for the square well potential
Il Nuovo Cimento, 1962From the analytic expression of theS-matrix we discuss the behaviour of the Regge trajectories for the square-well potential. First, the position of the poles for zero energy are found. For attractive potential, they are all real and infinite in number ; the value ofl being bounded from above.

Potential-well model in acoustic tweezers
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010Standing-wave acoustic tweezers are popularly used for non-invasive and non-contact particle manipulation. Because of their good penetration in biological tissue, they also show promising prospects for in vivo applications. According to the concept of an optical vortex, we propose an acoustics-vortex- based trapping model of acoustic tweezers.

Potential for Horizontal-Well Technology in the U.S.
Journal of Petroleum Technology, 2000Summary Application of horizontal wells has increased tremendously and had significant and positive results in the U.S. over the past decade. The pace of horizontal drilling for oil has remained high since 1990 (approximately 600 to 1,000 wells/yr).

Multiple Potential Well Precision Oscillators
IEEE Transactions on Circuits and Systems II: Express Briefs, 2021This research demonstrates how to take advantage of the nonlinear dynamics associated with multiple oscillation devices such that performance of a conventional single stable oscillation device can be improved. Conventional oscillators rely on nonlinear dynamics associated with a single stable oscillation.
