On quantum bound states in equiperiodic multi-well potentials I: Locally periodic potential sequences and Floquet/Bloch bands
Karl-Erik Thylwe
Two connected equiperiodic one-dimensional multi-well potentials of different well depths are studied. Floquet/Bloch energy bands for respective multi-well potential are found to b…
Note on a Floquet/Bloch-band fusion phenomenon in scattering by truncated periodic multi-well potentials
K-E Thylwe
A transmission phenomenon for a quantal particle scattered through a multi-well potential in one dimension is observed by means of an amplitude-phase method. The potential model co…
Quantum transmission for embedded, locally periodic potentials -- amplitude-phase approaches
Karl-Erik Thylwe
Quantum particle transmission through locally periodic potentials surrounded by symmetric exterior potentials is analyzed. Closed-form conditions for locating energy peaks of total…
Spinless particles in the field of unequal Scalar-Vector Yukawa potentials
Majid Hamzavi, Sameer M. Ikhdair, Karl-Erik Thylwe
We present analytical bound state solutions of the spin-zero Klein-Gordon (KG) particles in the field of unequal mixture of scalar and vector Yukawa potentials within the framework…
The Rotation-Vibration Spectrum of Diatomic Molecules with the Tietz-Hua Rotating oscillator
M. Hamzavi, A. A. Rajabi, K. -E. Thylwe
The Tietz-Hua (TH) potential is one of the very best analytical model potentials for the vibrational energy of diatomic molecules. By using the Nikiforov-Uvarov (NU) method, we hav…
Approximate analytical solution of the Yukawa potential with arbitrary angular momenta
M. Hamzavi, M. Movahedi, K. -E. Thylwe +1
The Yukawa potential is often used to compute bound-state normalizations and energy levels of neutral atoms. By using the generalized parametric Nikiforov-Uvarov (NU) method, we ha…
