Schwinger pair production with ultracold atoms
V. Kasper, F. Hebenstreit, M. Oberthaler +1
We consider a system of ultracold atoms in an optical lattice as a quantum simulator for electron-positron pair production in quantum electrodynamics (QED). For a setup in one spat…
Implementing quantum electrodynamics with ultracold atomic systems
V. Kasper, F. Hebenstreit, F. Jendrzejewski +2
We discuss the experimental engineering of model systems for the description of QED in one spatial dimension via a mixture of bosonic Na and fermionic Li atoms. The loca…
Simulating a quantum commensurate-incommensurate phase transition using two Raman coupled one dimensional condensates
V. Kasper, J. Marino, S. Ji +3
We study a transition between a homogeneous and an inhomogeneous phase in a system of one-dimensional, Raman tunnel-coupled Bose gases. The homogeneous phase shows a flat density a…
Revival of the magnetar PSR J1622-4950: observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR
F. Camilo, P. Scholz, M. Serylak +205
New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least ear…
