Effects of external fields on a two-dimensional Klein—Gordon particle under pseudo-harmonic oscillator interaction [PDF]
, 2012 We study the effects of the perpendicular magnetic and Aharonov—Bohm (AB) flux fields on the energy levels of a two-dimensional (2D) Klein—Gordon (KG) particle subjected to an equal scalar and vector pseudo-harmonic oscillator (PHO).

Encoding a qubit in a trapped-ion mechanical oscillator [PDF]
Nature, 2018 The stable operation of quantum computers will rely on error correction, in which single quantum bits of information are stored redundantly in the Hilbert space of a larger system. Such encoded qubits are commonly based on arrays of many physical qubits,

Rogue quantum harmonic oscillations [PDF]
Physica 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.

Relativistic Harmonic Oscillator with Spin Symmetry
, 2005 The eigenfunctions and eigenenergies for a Dirac Hamiltonian with equal scalar and vector harmonic oscillator potentials are derived. Equal scalar and vector potentials may be applicable to the spectrum of an antinucleion imbedded in a nucleus. Triaxial,

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
Advanced Functional Materials, EarlyView.A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Quantum-trajectory approach to the stochastic thermodynamics of a forced harmonic oscillator. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2011 I formulate a quantum stochastic thermodynamics for the quantum trajectories of a continuously monitored forced harmonic oscillator coupled to a thermal reservoir.

, 2007 Searching for a Lagrangian may seem either a trivial endeavour or an impossible task. In this paper we show that the Jacobi last multiplier associated with the Lie symmetries admitted by simple models of classical mechanics produces (too?) many ...

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

Advanced Functional Materials, EarlyView.The orbital‐current‐induced torque is investigated as an efficient method for controlling magnetization direction. By introducing Ti as an orbital current source in Ti/Ta (or Pt)/CoFeB/MgO structures, the switching current is reduced by ∼25% compared to a conventional spin‐orbit torque structure of Ta/CoFeB/MgO.

Nonequilibrium quantum fluctuation relations for harmonic systems in nonthermal environments
New Journal of Physics, 2013 We formulate exact generalized nonequilibrium fluctuation relations for the quantum mechanical harmonic oscillator coupled to multiple harmonic baths. Each of the different baths is prepared in its own individual (in general nonthermal) state.
