Ultracold Atom-Ion Systems in Hybrid Traps
(Humboldt-Universität zu Berlin, 2017-11-21)
This thesis deals with the theoretical description of a hybrid system of an ultracold neutral atom and a single ion. These hybrid atom-ion systems combine the key advantages of ultracold neutral atoms and ions. In particular, ...
Compositional and Thickness Effects on the Optical Properties of Zinc– Doped Selenium–Antimony Thin Films
(AJOL, 2018)
Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising
semiconductor for phase change memory devices due to its thermal stability and low power
consumption. The study investigated the effect ...
Ultracold Atom-Ion Systems in Hybrid Traps
(Humboldt-Universität zu Berlin, 2017-11-21)
This thesis deals with the theoretical description of a hybrid system of an
ultracold neutral atom and a single ion. These hybrid atom-ion systems have
attracted significant interest in recent years. They combine the key ...
Polariton and anti-polariton qubits in the Rabi model
(Research gate, 2017)
This paper presents a precise algebraic and physical framework for studying the dynamics and practical
applications of the quantum Rabi model. We redefine the quantum Rabi interaction in terms of polariton
and anti-polariton ...
Conserved excitation number and U(1)-symmetry operators for the anti-rotating (anti-Jaynes-Cummings) term of the Rabi Hamiltonian
(Research gate, 2017)
+ hω0sz+ hg (ˆa+ ˆa†)(s++ s−)(1a) where ω, ˆa, ˆa† are the quantized field mode angular frequency, annihilation and creation operators, while ω0, sz, s+, s− are the atomic state transition angular frequency and operators. ...
Rabi oscillations, entanglement and teleportation in the anti-Jaynes-Cummings model
(Cornell University, 2021)
This paper provides a scheme for generating maximally entangled qubit states in the anti-JaynesCummings interaction mechanism, so called entangled anti-polariton qubit states. We demonstrate
that in an initial vacuum-field, ...
Acoustics of fractal porous material and fractional calculus
(MDPI, 2021)
In this paper, we present a fractal (self-similar) model of acoustic propagation in a porous material with a rigid structure. The fractal medium is modeled as a continuous medium of non-integer spatial dimension. The basic ...
Flow of a Self-Similar Non-Newtonian Fluid Using Fractal Dimensions
(MDPI, 2022)
In this paper, the study of the fully developed flow of a self-similar (fractal) power-law fluid is presented. The rheological way of behaving of the fluid is modeled utilizing the Ostwald–de Waele relationship (covering ...
Transient Propagation of Longitudinal and Transverse Waves in Cancellous Bone: Application of Biot Theory and Fractional Calculus
(MDPI, 2022)
In this paper, the influence of the transverse wave on sound propagation in a porous medium with a flexible structure is considered. The study is carried out in the time domain using the modified Biot theory obtained by ...
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(arxiv.org, 2022)
The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC)
interaction is described by a reduced density operator. The purity of the state has been measured by
taking the trace of the ...
