A gauge invariant Debye mass and the complex heavy-quark potential

Autor: Yannis Burnier, Alexander Rothkopf

Following the original idea of Debye, we define and extract a gauge-invariant screening mass from the complex static in-medium heavy-quark potential VQQ¯, recently obtained from lattice QCD. To this end we derive a formula using concepts from both e

Due to the helical structure of DNA the process of DNA replication is topologically complex. Freshly replicated DNA molecules are catenated with each other and are frequently knotted. For proper functioning of DNA it is necessary to remove all of the

The pseudoscalar correlator is an ideal lattice probe for thermal modifications to quarkonium spectra, given that it is not compromised by a contribution from a large transport peak. We construct a perturbative spectral function incorporating resumme

DNA in bacterial chromosomes and bacterial plasmids is supercoiled. DNA supercoiling is essential for DNA replication and gene regulation. However, the density of supercoiling in vivo is circa twice smaller than in deproteinized DNA molecules isolate

Complex heavy-quark potential and Debye mass in a gluonic medium from lattice QCD

Autor: Yannis Burnier, Alexander Rothkopf

Publikováno v: ResearcherID

We improve and extend our study of the complex in-medium heavy quark potential and its Debye mass $m_D$ in a gluonic medium with a finer scan around the deconfinement transition and newly generated ensembles closer to the thermodynamic limit. On the
