In this report we review recent progress achieved in the understanding of heavy quarkonium
under extreme conditions from a theory perspective. Its focus lies both on quarkonium …

We review the recent status of the QCD sum rule approach to study the properties of
hadrons in vacuum and in hot or dense matter. Special focus is laid on the progress made in …

We study the properties of charmonium states at finite temperature in quenched QCD on
large and<? format?> fine isotropic lattices. We perform a detailed analysis of charmonium …

In this paper, we review recent progress toward understanding the nature of quarkonia in the
quark gluon plasma. We review the theory necessary to understand the melting of bound …

We calculate for the first time the complex potential between a heavy quark and antiquark at
finite temperature across the deconfinement transition in lattice QCD. The real and …

The first collisions of lead nuclei, delivered by the CERN Large Hadron Collider (LHC) at the
end of 2010, at a centre-of-mass energy per nucleon pair s NN= 2.76 TeV, marked the …

We investigate quarkonium mass spectra in external constant magnetic fields by using QCD
sum rules. We first discuss a general framework of QCD sum rules necessary for properly …

We investigate the mass spectra of open heavy flavor mesons in an external constant
magnetic field within QCD sum rules. Spectral Ansätze on the phenomenological side are …

In this paper, we propose an analytic continuation method to extract real-frequency spectral
functions from imaginary-frequency Green's functions of quantum many-body systems. This …

The computation of dynamical properties of nuclear matter, ranging from parton distribution
functions of nucleons and nuclei to transport properties in the quark-gluon plasma …
