A lower bound of concurrence for multipartite quantum systems
Xue-Na Zhu, Ming Li, Shao-Ming Fei
We present a lower bound of concurrence for four-partite systems in terms of the concurrence for part quantum systems and give an analytical lower bound for $…
Coherence of assistance and regularized coherence of assistance
Ming-Jing Zhao, Teng Ma, Shao-Ming Fei
We study the relation between the coherence of assistance and the regularized coherence of assistance introduced by Chitambar et al. [E. Chitambar et al., Phys. Rev. Lett. 116, 070…
Phylogenomics with Paralogs
Marc Hellmuth, Nicolas Wieseke, Marcus Lechner +3
Phylogenomics heavily relies on well-curated sequence data sets that consist, for each gene, exclusively of 1:1-orthologous. Paralogs are treated as a dangerous nuisance that has t…
Perelman's -functional on manifolds with conical singularities
Xianzhe Dai, Changliang Wang
In this paper, we develop the theory of Perelman's -functional on manifolds with isolated conical singularities. In particular, we show that the infimum of -functional over a…
Measure and detection of genuine multipartite entanglement for tripartite systems
Ming Li, Lingxia Jia, Jing Wang +2
It is a computationally hard task to certify genuine multipartite entanglement (GME). We investigate the relation between the norms of the correlation vectors and the detection of…
An introduction to random matrix theory
Gaëtan Borot
These are lectures notes for a 4h30 mini-course held in Ulaanbaatar, National University of Mongolia, August 5-7th 2015, at the summer school "Stochastic Processes and Applications…
