Does matter wave amplification work for fermions?

چکیده
We discuss the relationship between bosonic stimulation, density fluctuations, and matter wave gratings. It is shown that enhanced stimulated scattering, matter wave amplification, and atomic four-wave mixing do not require macroscopic occupation of a single quantum state. These processes are in principle possible for fermionic or nondegenerate samples, if they are prepared in a cooperative state. In practice, there are limitations due to short coherence times.

On the effective operators for Dark Matter annihilations
We consider effective operators describing Dark Matter (DM) interactions with Standard Model fermions. In the non-relativistic limit of the DM field, the operators can be organized according to their mass dimension and their velocity behaviour, i.e. whether they describe sor p-wave annihilations. The analysis is carried out for self-conjugate DM (real scalar or Majorana fermion). In this case, ...
متن کاملPhase-coherent amplification of matter waves
Phase-coherent matter-wave amplification was demonstrated using Bose- Einstein-condensed rubidium-87 atoms. A small seed matter wave was created with coherent optical Bragg diffraction. Amplification of this seed matter wave was achieved by using the initial condensate as a gain medium through the superradiance effect. The coherence properties of the amplified matter wave, studied with a matter...
متن کاملLaughlin wave function and one-dimensional free fermions.
Making use of the well-known phase space reduction in the lowest Landau level(LLL), we show that the Laughlin wave function for the ν = 1 m case can be obtained exactly as a coherent state representation of an one dimensional (1D) wave function. The 1D system consists of m copies of free fermions associated with each of the N electrons, confined in a common harmonic well potential. Interestingl...
متن کاملThe Hanbury Brown Twiss effect for atomic matter waves
This paper discusses our recent work on developing the matter wave analogs to the Hanbury Brown Twiss experiment. We discuss experiments using cold atoms, both bosons and fermions, both coherent and incoherent. Simple concepts from classical and quantum optics suffice to understand most of the results, but the ideas can also be traced back to the work of Einstein on the thermodynamics of Bose g...
متن کاملNon-Relativistic Limit of Neutron Beta-Decay Cross-Section in the Presence of Strong Magnetic Field
One of the most important reactions of the URCA that lead to the cooling of a neutron star, is neutron beta-decay ( ). In this research, the energy spectra and wave functions of massive fermions taking into account the Anomalous Magnetic Moment (AMM) in the presence of a strong changed magnetic field are calculated. For this purpose, the Dirac-Pauli equation for charged and neutral fermions is ...
