The multi-faceted inverted harmonic oscillator: Chaos and complexity

open access: yesSciPost Physics Core, 2021
The harmonic oscillator is the paragon of physical models; conceptually and computationally simple, yet rich enough to teach us about physics on scales that span classical mechanics to quantum field theory.

Rogue quantum harmonic oscillations [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
We show the existence and investigate the dynamics and statistics of rogue oscillations (standing waves) generated in the frame of the nonlinear quantum harmonic oscillator (NQHO). With this motivation, in this paper, we develop a split-step Fourier scheme for the computational analysis of NQHO.

Fingerprints of the quantum space-time in time-dependent quantum mechanics: An emergent geometric phase

open access: yesNuclear Physics B, 2022
We show the emergence of Berry phase in a forced harmonic oscillator system placed in the quantum space-time of Moyal type, where the time ‘t’ is also an operator.

Rapid Quantum Squeezing by Jumping the Harmonic Oscillator Frequency. [PDF]

open access: yesPhysical Review Letters, 2021
Quantum sensing and quantum information processing use quantum advantages such as squeezed states that encode a quantity of interest with higher precision and generate quantum correlations to outperform classical methods.

Quantum enhanced metrology in the search for fundamental physical phenomena

open access: yesSciPost Physics Lecture Notes, 2022
These notes summarize lectures given at the 2019 Les Houches summer school on Quantum Information Machines. They describe and review an application of quantum metrology concepts to searches for ultralight dark matter.

Market efficiency of the crude palm oil: Evidence from quantum harmonic oscillator

open access: yesJournal of Physics: Conference Series, 2020
This study examines the weak-form efficient market hypothesis of the crude palm oil market by adopting the quantum harmonic oscillator. This approach allows us to analyze market efficiency by estimating one parameter: the probability of finding the ...

Efficient algebraic solution for a time-dependent quantum harmonic oscillator

open access: yesPhysica Scripta, 2020
Using operator ordering techniques based on Baker-Campbell-Hausdorff (BCH) relations of the su(1,1) Lie algebra and a time-splitting approach, we present an alternative method of solving the dynamics of a time-dependent quantum harmonic oscillator for ...

The Poincare Lemma, Antiexact Forms, and Fermionic Quantum Harmonic Oscillator [PDF]

open access: yesResults in Mathematics, 2019
The paper focuses on various properties and applications of the homotopy operator, which occurs in the Poincaré lemma. In the first part, an abstract operator calculus is constructed, where the exterior derivative is an abstract derivative and the ...

Mpemba effect and super-accelerated thermalization in the damped quantum harmonic oscillator [PDF]

open access: yesQuantum
The behavior of systems far from equilibrium is often complex and unpredictable, challenging and sometimes overturning the physical intuition derived from equilibrium scenarios.

Driven harmonic oscillator as a quantum simulator for open systems [PDF]

open access: yes, 2006
We show theoretically how a driven harmonic oscillator can be used as a quantum simulator for non-Markovian damped harmonic oscillator. In the general framework, the results demonstrate the possibility to use a closed system as a simulator for open ...
