Suppression of dark-state polariton collapses in cold-atom quantum memory
Katja Gosar, Vesna Pirc Jevšenak, Tadej Mežnaršič +5
We observe dark-state polariton collapses and revivals in a quantum memory based on electromagnetically induced transparency on a cloud of cold cesium atoms in a magnetic field. Us…
Zeeman optical pumping of Rb atoms in a hollow core photonic crystal fibre
Tomasz Krehlik, Artur Stabrawa, Rafał Gartman +3
Preparation of an atomic ensemble in a particular Zeeman state is a critical step of many protocols for implementing quantum sensors and quantum memories. These devices can also be…
Cyclical properties of supply-side and demand-side shocks in oil-based commodity markets
Tomas Krehlik, Jozef Barunik
Oil markets profoundly influence world economies through determination of prices of energy and transports. Using novel methodology devised in frequency domain, we study the informa…
Measuring the frequency dynamics of financial connectedness and systemic risk
Jozef Barunik, Tomas Krehlik
We propose a new framework for measuring connectedness among financial variables that arises due to heterogeneous frequency responses to shocks. To estimate connectedness in short-…
Modeling and forecasting exchange rate volatility in time-frequency domain
Jozef Barunik, Tomas Krehlik, Lukas Vacha
This paper proposes an enhanced approach to modeling and forecasting volatility using high frequency data. Using a forecasting model based on Realized GARCH with multiple time-freq…
