Transient energy excitation in shortcuts to adiabaticity for the time-dependent harmonic oscillator [PDF]
, 2010 We study for the time-dependent harmonic oscillator the transient energy excitation in speed-up processes ('shortcuts to adiabaticity') designed to reproduce the initial populations at some predetermined final frequency and time.

Advanced Theory and Simulations, EarlyView.This study analyses the electronic structure of five‐electron spherical quantum dots with penetrable confinement potential. Spatial confinement and the influence of potential barrier height give rise to the unique properties of quantum dots. These effects lead to profound changes in their energy spectra and optical properties which play a key role in ...

Advanced Theory and Simulations, EarlyView.FMint is introduced as a multi‐modal foundation model that integrates human‐designed solvers and data‐driven methods for fast, accurate simulation of dynamical systems. FMint leverages in‐context learning within a transformer‐based framework to refine coarse numerical solutions.

Network Desynchronization with Sine Waves: from Synchrony to Asynchrony by Periodic Stimulation
Advanced Science, EarlyView.Exogenous alternating current fields are explored and interact with cerebral cortex slow waves in vitro and in silico. Varying frequency and amplitude of sine waves result in distinct network dynamics, from phase‐locking and entrainment to desynchronization. These responses occupy specific regions within the parameter space.

Harmonic Oscillator SUSY Partners and Evolution Loops
Symmetry, Integrability and Geometry: Methods and Applications, 2012 Supersymmetric quantum mechanics is a powerful tool for generating exactly solvable potentials departing from a given initial one. If applied to the harmonic oscillator, a family of Hamiltonians ruled by polynomial Heisenberg algebras is obtained.

A Sub‐Diffraction‐Limit Dimension All‐Plasmonic Optical Memory Using Non‐Linear Photochromism
Advanced Science, EarlyView.An all‐plasmonic optical memory is demonstrated by using nonlinear plasmonics on a sub‐diffraction limit plasmonic nanowire waveguide coated with a photochromic diarylethene that supports the complete memory processes, “Write”, “Erase”, and “Readout” the memory ON/OFF states. Abstract The development of compact, high‐speed, and energy‐efficient optical

On The Harmonic Oscillator Group [PDF]
, 2011 We discuss the maximum kinematical invariance group of the quantum harmonic oscillator from a view point of the Ermakov-type system. A six parameter family of the square integrable oscillator wave functions, which seems cannot be obtained by the standard
