Fusion hindrance and Pauli blocking in Ni58+Ni64

Bose-Enhancement and Pauli-Blocking Effects in Transport Models

The ability of semi-classical transport models to correctly simulate Pauli blocking and Bose enhancement is discussed. In the context of simple quantum mechanical systems, it is shown that using (1 ± f) enhancements is inadequate to describe systems far from equilibrium. The relaxation of (1 + f) descriptions toward equilibrium is studied both in the context of simple models, including a hot pi...

Effect of Pauli repulsion on fusion

epl draft Optical traps for electron produced by Pauli blocking

We propose a mechanism to trap electrons in a semiconductor using counterpropagating laser beams. The trapping comes from Pauli blocking between electron and virtual exciton coupled to unabsorbed photons. Electron exchange allows for the possibility of momentum transfer between photon and electron. This leads to a sinusoidal trap for electron with a period determined by the laser beam modulatio...

Enhanced Pauli blocking of light scattering in a trapped Fermi gas

Pauli blocking of spontaneous emission by a single excited-state atom has been predicted to be dramatic at low temperature when the Fermi energy EF exceeds the recoil energy ER. The photon scattering rate of a ground-state Fermi gas can also be suppressed by occupation of the final states accessible to a recoiling atom; however, suppression is diminished by scattering events near the Fermi edge...

Pauli blocking of collisions in a quantum degenerate atomic Fermi gas.

We have produced an interacting quantum degenerate Fermi gas of atoms composed of two spin states of magnetically trapped 40K. The relative Fermi energies are adjusted by controlling the population in each spin state. Thermodynamic measurements reveal a resulting imbalance in the mean energy per particle between the two species, which is a factor of 1.4 at our lowest temperature. This imbalance...
