Likelihood-free inference and gamma-ray astronomy Estimating (physical) model parameters θ from experimental data x is one of the core tasks in any field of physics. Statistical estimation procedures frequently make use of the likelihood function p(x|θ). Often, the likelihood can not be evaluated explicitly, but can be efficiently sampled from....

Forcing neutrinos to obey the holographic principle Gravity does not like the vast amounts of states present in QFT, and quantum gravitational effects are expected to drastically reduce the dimension of the QFT Hilbert space. This is e.g. achieved by "operator dressing", which changes the commutation relations of quantum fields....
