One-neutron removal strength of 7He into 6He using the complex scaling method

We study the one-neutron removal strength of the 7He ground state, which provides us with the 6He-n component in 7He. The He isotopes are described on the basis of the 4He+Xn cluster model (X=1,2,3). The complex scaling method is applied to describe not only the Gamow resonances but also the nonresonant continuum states of valence neutrons, with the correct boundary condition of particle decays. The one-neutron removal strength of 7He into the unbound states of 6He is calculated using the complex-scaled Green's function, in which a complex-scaled complete set of 4He+n+n states is adopted. Using this framework, we investigate resonant and nonresonant contributions of the strength, which individually produce specific structures in the distributions. In addition, we propose a method to obtain the real-value strength using the complex values of spectroscopic factors of Gamow states. As a result, the 6He(2+) resonance is found to give the largest contribution.Comment: 11 pages, 10 figures, Corrected typo

Control strategies for arbitration in cryptocurrencies

Tato práce je zaměřena především na obchodování kryptocyrrence mezi různými exhnangers, které poskytují vysokou bezpečnost, spolehlivost a tzv. API. V současné době existují situace, kdy se ve stejné instanci obchoduje stejná kryptocyrrence za výrazně odlišné ceny na různých burzách. Současný nákup / prodej na různých místech by proto generoval zisk, absolutně bez rizika. Tento druh obchodování se nazývá arbitráž. Lze to shrnout tak, že hlavním cílem práce je ověřit, zda takový systém může existovat či nikoliv, a také napsat webovou stránku pro zobrazení získaných výsledků.This work is, mainly, dedicated to trading cryptocyrrencies between different exhnangers that provide high safety, reliability and so-called API. Nowadays, there are situations where at the same instance the same cryptocyrrency is traded at significantly different prices at different exchanges. Concurrent purchase/sales at various locations would therefore generate profits, absolutely without risk. This kind of trading is called arbitration. It can be summed up by saying that the main aim of the thesis is to verify whether such a system can exist or not and also to write a website to display the obtained results
