  - OPEN SYSTEMS & INFORMATION DYNAMICS - Year 2011

  The Hamiltonians of the considered bi-partite systems are of the form $$ H_{S,R} = H_S /times 1_R + Q_{S} /times M_R + 1_S /times H_R $$ Subindex $S$ corresponds to the observed system and $R$ to the reservoir (the enviroment of $S$). Two classes of systems are distinguished: the discrete-continuous...

  - Colloquium Mathematicum - Year 2006

  Dowodzi się, że zbiór tych półgrup operatorów Markowa na klasie Schattena C1, dla których w mocnej topologii operatorowej T(t) jest zbieżne do operatora Markowa Q, gdzie Q jest 1-wymiarową projekcją, jest zbiorem rzadkim w zbiorze wszystkich półgrup Markowa.

  - PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY - Year 2017

  We prove a Wiener-Wintner ergodic type theorem for a Markov representation of a right amenable semitopological semigroup.

• Anomalous decay of quantum correlations of quantum-dot qubits

  Publication

  - PHYSICAL REVIEW A - Year 2013

  We study the evolution of quantum correlations, quantified by the geometric discord, of two excitonic quantum-dot qubits under the influence of the phonon environment. We show that the decay of these correlations differs substantially from the decay of entanglement. Instead of displaying sudden-death-type behavior, the geometric discord shows a tendency to undergo transitions between different types of decay, is sensitive to nonlocal...
