Dielectric function in WSe2
Tiberius O. Cheche, Yia-Chung Chang
We develop a Hartree-Fock numerical method for computing the band structure of a two-dimensional Wigner crystal in an electron gas at zero temperature. The ground state is assumed…
Polarization of Charged Spherical Dielectric Core-Shell
A. Marin, O. Ianc, T. O. Cheche
Two point charges are placed in a spherical dielectric core-shell embedded in a dielectric environment, one of the charges being located in the core and the other in the shell. The…
Two-Body Motion in Central Conservative Force Fields
O. Ianc, A. Marin, T. O. Cheche
The two-body motion for the gravitational and linear elastic central conservative force field is discussed by comparing the differential equations of motions. The inverse and direc…
The dog-and-rabbit chase problem
R. A. Gutoiu, T. O. Cheche
The dog-and-rabbit chase problem is a classical problem that illustrates the concepts of elementary kinematics and, therefore, can be used in introductory mechanics teaching. By de…
Pulsejet engine dynamics in vertical motion using momentum conservation
Tiberius O. Cheche
The momentum conservation law is applied to analyse the dynamics of pulsejet engine in vertical motion in a uniform gravitational field in the absence of friction. The model predic…
Coin Toss Modeling
Razvan C. Stefan, Tiberius O. Cheche
The torque-free motion of rigid body in gravitational field is analyzed. The coin lands on a soft surface (such as the palm of the hand) that allows no bouncing. The model assumes…
