Instantonic Approach to Triple-Well Potential [PDF]

open access: yesModern Physics Letters A, 1997
By using the usual instanton method, we obtain the energy splitting due to quantum tunneling through the triple-well barrier. It is shown that the term related to the midpoint of the energy splitting in propagator is quite different from that of double-well case, in that it is proportional to the algebraic average of the frequencies of the left and ...

Kink localization under asymmetric double-well potentials [PDF]

open access: yesPhysical Review E, 2012
We study diffuse phase interfaces under asymmetric double-well potential energies with degenerate minima and demonstrate that the limiting sharp profile, for small interface energy cost, on a finite space interval is in general not symmetric and its position depends exclusively on the second derivatives of the potential energy at the two minima (phases)

Nonlinear dynamics in double square-well potentials

open access: yesTheoretical and Mathematical Physics, 2007
Considering the coherent nonlinear dynamics in double square well potential we find the example of coexistence of Josephson oscillations with a self-trapping regime. This macroscopic bistability is explained by proving analytically the simultaneous existence of symmetric, antisymmetric and asymmetric stationary solutions of the associated Gross ...

Global existence and finite time blowup for a nonlocal semilinear pseudo-parabolic equation

open access: yesAdvances in Nonlinear Analysis, 2020
In this paper, the initial boundary value problem for a nonlocal semilinear pseudo-parabolic equation is investigated, which was introduced to model phenomena in population dynamics and biological sciences where the total mass of a chemical or an ...

Global existence and dynamic structure of solutions for damped wave equation involving the fractional Laplacian

open access: yesDemonstratio Mathematica, 2021
We consider strong damped wave equation involving the fractional Laplacian with nonlinear source. The results of global solution under necessary conditions on the critical exponent are established.

Metastability of Asymptotically Well-Behaved Potential Games [PDF]

open access: yes, 2014
One of the main criticisms to game theory concerns the assumption of full rationality. Logit dynamics is a decentralized algorithm in which a level of irrationality (a.k.a. "noise") is introduced in players' behavior.

Anomalous jumping in a double-well potential [PDF]

open access: yes, 1999
Noise induced jumping between meta-stable states in a potential depends on the structure of the noise. For an $\alpha$-stable noise, jumping triggered by single extreme events contributes to the transition probability.

Real‐Space Observation of Potential Reconstruction at Metallic/Insulating Oxide Interface

open access: yesAdvanced Materials Interfaces, 2023

Quantum Information Entropy for Another Class of New Proposed Hyperbolic Potentials

open access: yesEntropy, 2023
In this work, we investigate the Shannon entropy of four recently proposed hyperbolic potentials through studying position and momentum entropies.
