Muon-pair creation by two x-ray laser photons in the field of an atomic nucleus.
The generation of muon-antimuon pairs is calculated in the collision of an ultrarelativistic bare ion with an intense x-ray laser beam. The reaction proceeds nonlinearly via absorption of two laser photons. By systematic study throughout the nuclear chart, we show that the interplay between the nuclear charge and size, along with the possibility of nuclear excitation leads to saturation of the ...
متن کاملResonant sum frequency generation with time-energy entangled photons.
We describe a technique for enhancing the efficiency of sum frequency generation using entangled signal and idler photons. By resonating the sum frequency field, we observe that the generated power varies linearly with input power and is increased by a factor of 12.

Charged pion pair production by two photons from a chiral sum rule
The cross-section for a charged pion pair production by two photons is evaluated by using the low energy expression previously obtained from current algebra and PCAC which involves an integral over vector and axial-vector spectral functions. Data on the latter obtained from τ-decay as measured by the ALEPH collaboration is then inserted in the integral which is appropriately modified in order t...
