Hanbury Brown-twiss Interferometry in Subatomic Particles

Detection of Single Photon Emission by Hanbury-Brown Twiss Interferometry

We prepare a solution of nano-diamond particles on a glass microscope slide with a target concentration of 1 × 10 M. Using a confocal microscope, we observe photons emitted from the particles via excitation from a pulsed 532 nm solid state laser at 840 μW. A Hanbury Brown and Twiss interferometer is used to probe these photons for evidence of antibunching. At this time, we did not observe antib...

The Hanbury Brown and Twiss effect

If we had just 2Nk in the sum, this would be proportional to the energy of each mode times the number of quanta in each mode, summed over all modes. In fact, we have a ‘zero point’ contribution even when Nk = 0. It has exactly the same origin as the 12~ω ground state energy of the simple harmonic oscillator. In this case, the infinite number of modes means that the sum in Eq. (3) is not converg...

The fermionic hanbury brown and twiss experiment

A Hanbury Brown and Twiss experiment for a beam of electrons has been realized in a two-dimensional electron gas in the quantum Hall regime. A metallic split gate serves as a tunable beam splitter to partition the incident beam into transmitted and reflected partial beams. In the nonequilibrium case the fluctuations in the partial beams are shown to be fully anticorrelated, demonstrating that f...

Hanbury Brown–Twiss interferometry for fractional and integer Mott phases

The theoretical framework of Hanbury Brown–Twiss interferometry (HBTI) is used to study integer and fractionally filled Mott insulator (MI) phases in period-2 optical superlattices. In contrast to the quasimomentum distribution, this second order interferometry pattern exhibits high contrast fringes in the insulating phases. Our detailed study of HBTI suggests that this interference pattern sig...
