Normal Fermi-Walker Derivative in E_{1}^{3}

In this paper, firstly, in $E_1^3$, we defined normal Fermi-Walker derivative and applied for the adapted frame. Normal Fermi-Walker parallelism, normal non-rotating frame, and Darboux vector expressions of normal Fermi-Walker derivative by normal Fermi-Walker derivative are given for adapted frame. Being conditions of normal Fermi-Walker derivative and normal non-rotating frame are examined fo...

Fermi Acceleration

Fermi acceleration is a mechanism, first suggested by Enrico Fermi in 1949, to explain heating of particles in cosmic rays. Fermi studied charged particles being reflected by the moving interstellar magnetic field and either gaining or losing energy, depending on whether the ”magnetic mirror” is approaching or receding. In a typical environment, Fermi argued, the probability of a head-on collis...

Quantum Degeneracy in an Atomic Fermi-Fermi-Bose Mixture

This thesis deals with dilute fermionic and bosonic quantum gases in the nK temperature regime. In the work presented here, the first quantum-degenerate mixture of two different fermionic atomic species and the first triple-degenerate Fermi-Fermi-Bose mixture were produced. The quantum-degenerate mixtures were realized using sympathetic cooling of the fermionic species 6Li and 40K by an evapora...
