In quantum many-body physics, the analytic continuation of Greens' functions is a well-known problem.
The problem is ill-posed in the sense that the transformation kernel becomes chaotic for large energies and thus small noise
creates huge differences in the resulting spectral density function.
Some techniques in the field of machine learning, in particular neural networks, are known for...
The emission of soft photons plays a fundamental role in our understanding of quantum field theories. However, the calculations for one-photon emission observables appear to be incompatible with the experimental measurements. Future upgrades to the ALICE detector at the LHC are proposed to measure soft photon emission, which is of great interest. Predictions for processes involving soft...
In the most commonly adopted approach to transverse momentum-dependent (TMD) factorization, the TMD parton distributions are expressed in position space, which is Fourier-conjugate to the transverse momenta. The transverse momentum-dependent observables are obtained through a two-dimensional Fourier transform, which can be reduced to a one-dimensional Hankel transform. Computation of this...
I am going to discuss the results of the entanglement entropy of proton's constituents as have been obtained recently within Kharzeev-Levin approach. The proposal resolves the paradox coming from the fact that the proton is a pure state but its constituents are incoherent states of partons. The resulting entropy formula can be shown to describe measured data as well as agrees with...
