The lepton pair production in ultraperipheral collisions is studied in the classical field
approximation. We derive a general form of the cross section in terms of photon distributions …

Dark matter particles gravitationally bound to our Galaxy should exhibit a characteristic
speed distribution limited by their escape velocity at the position of Earth (v esc≃ 550 km/s) …

Quantum state tomography is a daunting challenge of experimental quantum computing,
even in moderate system size. One way to boost the efficiency of state tomography is via …

With the advent of detectors with sub-keV sensitivities, atomic ionization has been identified
as a promising avenue to probe possible neutrino electromagnetic properties. The …

A long-standing problem in quantum mechanics is the minimum number of observables
required for the characterization of unknown pure quantum states. The solution to this …

Quantum state tomography (QST) is the art of reconstructing an unknown quantum state
through measurements. It is a key primitive for developing quantum technologies. Neural …

Quantum state tomography via local measurements is an efficient tool for characterizing
quantum states. However, it requires that the original global state be uniquely determined …

Relativistic millicharged particles (χ q) have been proposed in various extensions to the
standard model of particle physics. We consider the scenarios where they are produced at …

The frequency dependent conductivity σ (ω) of the strongly coupled quark-gluon plasma is
estimated using a bottom up holographic model that can adequately describe recent lattice …
