• #### No Time at the End of the Tunnel ﻿

(Communications Physics – Nature, 2018-08-21)
Modern atto-second experiments seek to provide an insight into a long standing question: “how much time does a tunnelling particle spend in the barrier?” Traditionally, quantum theory relates this duration to the delay ...
• #### Non-Markovian models of the growth of a polymer chain ﻿

(Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015-12-31)
Using simple exactly solvable models, we show that event-dependent time delays may lead to significant non-Poisson effects in the statistics of polymer chain growth. The results are confirmed by stochastic simulation of ...
