Collective neutrino oscillations: Many-body non-forward effects and non-classicality
Julien Froustey, Ermal Rrapaj, Yuhao Liu +3
Neutrino evolution in dense astrophysical environments is typically described either within a quantum kinetic framework, which neglects the build-up of multi-body correlations, or…
Many-body collective neutrino oscillations: recent developments
Amol V. Patwardhan, Michael J. Cervia, Ermal Rrapaj +2
Neutrino flavor transformations in core-collapse supernovae and binary neutron star mergers represent a complex and unsolved problem that is integral to our understanding of the dy…
Sphaleron Transition Rates and the Chiral Magnetic Effect
Joseph I. Kapusta, Ermal Rrapaj, Serge Rudaz
The chiral magnetic effect is a novel quantum phenomenon proposed for high-energy nuclear collisions but which has yet to be observed. We quantify the axial charge relaxation time,…
Exact solution of multi-angle quantum many-body collective neutrino flavor oscillations
Ermal Rrapaj
I study the flavor evolution of a dense neutrino gas by considering vacuum contributions, matter effects and neutrino self-interactions. Assuming a system of two flavors in a unifo…
Rate of dark photon emission from electron positron annihilation in massive stars
Ermal Rrapaj, Andre Sieverding, Yong-Zhong Qian
We calculate the rate of production of dark photons from electron-positron pair annihilation in hot and dense matter characteristic of supernova progenitors. Given the non-linear d…
Charmonium in lattice QCD and the non-relativistic quark-model
Jozef J. Dudek, Ermal Rrapaj
We compare the results of a numerical lattice QCD calculation of the charmonium spectrum with the structure of a general non-relativistic potential model. To achieve this we form t…
