Dark and bright solitons in a Bose-Einstein condensate with a Feshbach resonance
Yüce, Cem; Kılıç, Abidin (Royal Swedish Acad Sciences, 2007)Both dark and bright solitons are constructed exactly for a Bose - Einstein condensation with a time-dependent scattering length in an expulsive parabolic potential. It is shown analytically how the size of the cloud and ... -
Dynamical Casimir effect for a swinging cavity
Yüce, Cem; Özçakmaklı, Zalihe (IOP Publishing LTD, 2009)The resonant scalar particle generation for a swinging cavity resonator in the Casimir vacuum is examined. It is shown that the number of particles grows exponentially when the cavity rotates at a specific external frequency. -
The dynamical Casimir effect for two oscillating mirrors in 3D
Yüce, Cem; Özçakmaklı, Zalihe (IOP Publishing LTD, 2008)The generation of photons in a three-dimensional rectangular cavity with two moving boundaries is studied by using the multiple scale analysis (MSA). It is shown that the number of photons are enhanced for the cavity whose ... -
Feshbach resonance and growth of a Bose-Einstein condensate
Yüce, Cem; Kılıç, Abidin (American Physical Soc, 2006)The Gross-Pitaevskii gain equation is used to model atom laser and Bose-Einstein condensation (BEC) fed by the surrounding thermal cloud. It is shown that the number of atoms continuously injected into BEC from the reservoir ... -
Inverted oscillator
Yüce, Cem; Kılıç, Abidin; Coruh, A. (IOP Publishing LTD, 2006)The inverted harmonic oscillator problem is investigated quantum mechanically. The exact wavefunction for the confined inverted oscillator is obtained and it is shown that the associated energy eigenvalues are discrete, ... -
Oscillating and rotating boundary conditions in quantum mechanics
Yüce, Cem; Özçakmaklı, Zalihe (IOP Publishing LTD, 2011)We consider a particle in an oscillating cavity and in a rotating cavity in the context of moving boundary problems in quantum physics. We use the multiple-scale analysis method to solve the Schrodinger equation subject ... -
Pseudo PT symmetric lattice
Yüce, Cem (Springer, 2015)We study pseudo PT symmetry for a tight binding lattice with a general form of the modulation. Using high-frequency Floquet method, we show that the critical non-Hermitian degree for the reality of the spectrum can be ... -
PT symmetric Floquet topological phase
Yüce, Cem (Springer, 2015)In this paper, we study the existence of Floquet topological insulators for PT symmetric non-Hermitian Hamiltonians. We consider an array of waveguide in 1D with periodically changing non-Hermitian potential and predict ...
