In this study, we investigated the sensitivity of the positron annihilation rate during thermalization to variations in the elastic scattering phase shifts and the corresponding cross sections. We employed a Boltzmann equation solver to simulate positr…
We show that a two-sided hybrid optomechanical (OM) system is capable of storing and retrieving information with controllable memory efficiency. The control of OM coupling, primarily arising from optomechanically induced transparency, plays a central r…
This study presents a comprehensive experimental and theoretical characterisation of Stokes polarimetry in potassium (K) vapour on the D1 line. Measurements were performed in the weak-probe regime, investigating the influence of neon buffer gas in the …
High-lying Rydberg and autoionizing (AI) states of thorium (Th) have been studied via resonance laser ionization spectroscopy at both TRIUMF Canada’s particle accelerator center and Oak Ridge National Lab (ORNL). Multiple Rydberg series converging to t…
We present an analysis based on results of numerical model simulations of microscopic high-order harmonic generation in a cross-polarized laser set-up using the time-dependent Schrödinger equation. The set-up consists of an intense laser pulse at the f…
The precise control of nuclear spin states is crucial for a wide range of quantum technology applications. Here, we propose a fast and robust single-qubit gate in Sr utilizing the concept of optical nuclear electric resonance (ONER). ONER exploits the …
Employing the dual laser plasma technique, the extreme ultraviolet photoabsorption spectra of Zr3+, Zr4+ and Zr5+ spanning the energy range from 58 to 230 eV were measured with an energy resolution of . The measured spectra are carefully analyzed by co…
The interaction of an incoming beam carrying orbital angular momentum with a rotating body leads to a rotational Doppler shift in the frequency of the outgoing or scattered beam. This shift reveals the characteristics of the rotation. When the axes of …
This paper proposes a theoretical model for a heat engine operating on the Otto cycle, employing a two-qubit Heisenberg chain as its working substance. This system is subjected to an external, time-dependent homogeneous magnetic field and a symmetric c…
This work studies the non-equilibrium dynamics of polarized fermions in a one-dimensional cavity-assisted hopping lattice with an incommensurate potential. By employing the Keldysh Green’s function method to solve the equations of motion, we demonstrat…
