“…We conclude by observing that the effect of particle statistics in different quantum phenomena is regarded to be of much importance motivating newer tests beyond traditional arenas [26]. Our approach of studying the influence of particle statistics on the arrival time distribution provides an independent manifestation of the fundamental quantum property of indistinguishability.…”

We study the effect of quantum statistics on the arrival time distribution of quantum particles computed through the probability current density. It is shown that symmetrization or asymmetrization of the wave function affects the arrival time distribution for even freely propagating particles. In order to investigate the effect of statistics on the weak equivalence principle in quantum mechanics (WEQ), we then compute the mean arrival time for wave packets in free fall. The violation of WEQ through the effect of statistics on the mass-dependence of the mean arrival time is clearly exhibited. We finally evaluate the effect of spin on the violation of WEQ using a different approach by including an explicit spin-dependence in the probability current distribution, and compare it with the approach using particle statistics. Our results show WEQ re-emerges smoothly in the limit of large mass.

“…Note that the test described in [1] does not involve electromagnetic excitations that can be treated as non-bosonic over their entire time of existence. Instead, the electromagnetic field is prepared in a coherent and intrinsically bosonic laser state.…”

It is an empirical question whether photons always obey Bose-Einstein statistics, but devising and interpreting experimental tests of photon statistics can be a challenge. The nonrelativistic cross section for Compton scattering illustrates how a small admixture ν of wrong-sign statistics leads to a loss of gauge invariance; there is a large anomalous amplitude for scattering timelike photons. Nevertheless, one can interpret the observed transparency of the solar wind plasma at low frequencies as a bound ν < 10 −25 if Lorentz symmetry is required. If there is instead a universal preferred frame, the bound is ν < 10 −14 , still strong compared with previous results.

“…There have been therefore a lot of interest in experiments looking for Bose symmetry violation as a means of testing the present theoretical framework. Theoretical ideas and experimental investigations for Bose symmetry violations have looked at the spin-0 nucleus of oxygen 16 O [3, 4], molecules such as 16 O 2 and CO 2 [5][6][7][8], photons [9][10][11][12][13][14], pions [15] and Bose symmetry violating transitions [16][17][18][19][20][21][22]. Theoretically a scenario where Bose symmetry is not exact swings open doors to a plethora of avenues for new physics [23][24][25][26][27].…”
