For the first time, we show the coupling between advanced atomistic process and device modeling and its applicability for 65nm PMOS and NMOS technology. This technique can be used to simulate and get some important insights to improve and optimize future CMOS devices
The collapse of a trapped boson-fermion mixture with attraction between bosons and fermions is investigated in the framework of the effective Hamiltonian for the Bose system. The properties of an Rb and K mixture are analyzed quantitatively at T=0. We find numerically solutions of the modified Gross-Pitaevskii equation which continuously go from the stable(More)
An effective Hamiltonian for the Bose subsystem for the mixture of ultracold atomic clouds of bosons and fermions is obtained by integrating out the fermion degrees of freedom. Using the effective Hamiltonian, a collapse of the trapped boson-fermion mixture due to the boson-fermion attractive interaction without and in the presence of the quantized vortices(More)
An effective Hamiltonian for the Bose system in the mixture of ultracold atomic clouds of bosons and fermions is obtained by integrating out the Fermi degrees of freedom. An instability of the Bose system is found in the case of attractive interaction between components in good agreement with the experiment on the bosonic 87Rb and fermionic 40K mixture. The(More)
