Dynamical generation of phase-squeezed states two-component Bose-Einstein condensates
font style='font-size:12px;'>
2010/11/22
As an “input” state of a linear (Mach-Zehnder or Ramsey) interferometer, the phase-squeezed
state proposed by Berry and Wiseman exhibits the best sensitivity approaching to the Heisenberg
limit [Phy...
Photon spectra from quark generation by WIMPs
Dark matter indirect searches WIMPs photon spectra and quark pairs annihilation
font style='font-size:12px;'>
2010/11/16
If the present dark matter (DM) in the Universe annihilates into Standard Model (SM)particles, it must contribute to the gamma ray fluxes that are detected on the Earth. The magnitude of such contribu...
CAT-generation of ideals
CAT-generation of ideals math
font style='font-size:12px;'>
2010/11/19
We consider the problem of generating all ideals of a poset. It is a long standing open problem, whether or not the ideals of any poset can be generated in constant amortized time, CAT for short. We ...
