Persistence of a Brownian particle in a Time Dependent Potential
, 2012 We investigate the persistence probability of a Brownian particle in a harmonic potential, which decays to zero at long times -- leading to an unbounded motion of the Brownian particle.

Exponential decay in the stark effect [PDF]
Communications in Mathematical Physics, 1980 LetH=−Δ+V+Fx1 withV(x1,x⊥) analytic in the first variable andV(x1+ia, x⊥) bounded and decreasing to zero asx → ∞ for eacha ∈ ℝ. Let ψ be an eigenvector of −Δ+V with negative eigenvalue. Among our results we show that forF≠0, (ψ,e−Hψ) decays exponentially at a rate governed by the positions of the resonances ofH.

Fidelity Decay as an Efficient Indicator of Quantum Chaos
, 2002 Recent work has connected the type of fidelity decay in perturbed quantum models to the presence of chaos in the associated classical models. We demonstrate that a system's rate of fidelity decay under repeated perturbations may be measured efficiently ...

Schottky anomaly observed in 31P NMR for 31P-doped Si
Journal of Analytical Science and Technology, 2010 The Schottky anomaly, which happens when the heat capacity of nuclei is comparable to that of electrons, was observed in NMR for phosphorous doped silicon. The anomaly appears as an abnormal double exponential decay in the nuclear spin relaxation at very

MAMGD: Gradient-Based Optimization Method Using Exponential Decay
TechnologiesOptimization methods, namely, gradient optimization methods, are a key part of neural network training. In this paper, we propose a new gradient optimization method using exponential decay and the adaptive learning rate using a discrete second-order ...

Boundary Stabilization of Memory Type for the Porous-Thermo-Elasticity System
Abstract and Applied Analysis, 2009 We consider the one-dimensional viscoelastic Porous-Thermo-Elastic system. We establish a general decay results. The usual exponential and polynomial decay rates are only special cases.
