Bounds on skewness and kurtosis of steady state currents
Krzysztof Ptaszynski
Current fluctuations are a powerful tool to unravel the underlying physics of the observed transport process. This work discusses some general properties of the third and the fourt…
Finite-frequency noise in non-Markovian systems: A Markovian embedding approach
Krzysztof Ptaszynski
I present an approach to calculate the finite-frequency quantum noise in systems strongly coupled to structured reservoirs based on the Markovian embedding. This technique consists…
Coherence-enhanced constancy of a quantum thermoelectric generator
Krzysztof Ptaszynski
The study shows that presence of the quantum coherent, unitary component of the evolution of the system can improve constancy of heat engines, i.e., decrease fluctuations of the ou…
Revealing the internal spin dynamics in a double quantum dot by periodic voltage modulation
Krzysztof Ptaszynski
The paper proposes the method to analyze the internal dynamics of nanoscopic systems by periodic modulation of the electrochemical potentials of the attached leads and measuring th…
Waiting time distribution revealing the internal spin dynamics in a double quantum dot
Krzysztof Ptaszynski
Waiting time distribution and the zero-frequency full counting statistics of unidirectional electron transport through a double quantum dot molecule attached to spin-polarized lead…
Nonrenewal statistics in transport through quantum dots
Krzysztof Ptaszynski
The distribution of waiting times between successive tunneling events is an already established method to characterize current fluctuations in mesoscopic systems. Here, I investiga…
