Indefinite causal order: gravitational proposals and definitions of events in perspective
Abstract: 
Time in general relativity is dynamical and the ticking rates of clocks experiencing different gravitational fields are distinct. Thus, puzzling effects could happen in a theoretical configuration where a massive body is in a quantum superposition state of different positions. The idea of indefinite causal order comes from the possibility that, in these configurations, the causal relations among events would be in a superposition state as well. For instance, two events could be in a superposition of being in the past and future of each other. It is suggested that these configurations could be tested operationally using the proper times measured by clocks lying on such quantum spacetime. An important research goal nowadays is to find means compatible with the current technological capabilities that make these theoretical ideas possible to be tested. Here I will talk about our more recent results, where we show how to simulate an indefinite causal order with accelerated agents, and how to perform it with the gravity of Earth with current technology. Moreover, with the same techniques, it is possible to optimize these tasks in a quantum spacetime, what makes a hypothetical experiment several orders of magnitude more efficient. Beyond the discussion of applicability in experiments, it is also important to understand the fundamentals and interpretations of each proposal in the field of indefinite causal order. The interpretation of such tasks are under discussion and there is absolutely no consensus among the specialists. This disagreement is based on the fact that many different definitions of events are being considered by authors. I will raise this discussion in an unbiased way, summarizing all the definitions of events in the field of indefinite causal order and how they affect the interpretation of different proposals. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Peter.Matak@fmph.uniba.sk Tue, 29 Nov 2022 12:33:00 +0100 https://uniba.sk/ Thursday 1.12.2022 at 14:00, Lecture rook F2/51 Mgr.

A computer-free classification of orientably-regular maps of genus $p+1$ for prime $p$
Abstract:
In 2010, M. Conder, T. Tucker and the presenter published a classification of orientably-regular maps of genus $p+1$ for primes $p > 13$, with a computer-free proof for $p > 83$; for primes $p$ in the range $17 \le p \le 83$ part of the argument relied on computational results of M. Conder. Classification of such maps for $p\le 7$ was available by earlier results going back to 1930s -- 1980s, however, in a number of cases without explicit proofs. In the talk we will give an outline of methods and results leading to a computer-free classification of orientably-regular maps of genus $p+1$ for all primes $p\le 83$ (and hence for all primes $p$). This is a report on a joint work with M. Bachraty, M. Conder and J. Siagiova.

The latest results of the Higgs boson and top quark studies from the LHC
Abstract:
The seminar is mainly focused on the latest results regarding the physics of the Higgs boson and top quark obtained in the LHC experiments. At the same time, these results are analysed in connection with the current status of testing of the Standard Model and the impacts on such issues of particle physics as is the vacuum stability or the internal consistency of the Standard Model. The issue of further advancement of particle physics is also considered. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Jaroslav.Stanicek@fmph.uniba.sk Thu, 24 Nov 2022 17:35:00 +0100 http://https://uniba.sk/en/news-detail/back_to_page/aktuality-43/article/uk-odovzdala-cestny-doktorat-nemeckemu-farmakologovi-joachimovi-neumannovi/ Bratislava, 23 November 2022: Today, Comenius University Bratislava awarded the title of Doctor...
