The classical random walk formalism plays an important role in a wide range of applications.
Its quantum counterpart, the quantum walk, is proposed as an important theoretical model …

The persistent accumulation of carbon dioxide (CO2) in the atmosphere represents a major
environmental threat facing the world today. The electrochemical reduction of CO2 (ERCO2) …

In this work we aim at proving central limit theorems for open quantum walks on Z^ d Z d. We
study the case when there are various classes of vertices in the network. In particular, we …

The radical pair mechanism is by now the most prominent candidate for a biologically
relevant quantum effect of magnetic fields. Recently, N. Ikeya and JR Woodward …

Radical-ion-pair reactions, central for understanding the avian magnetic compass and spin
transport in photosynthetic reaction centers, were recently shown to be a fruitful paradigm of …

The main results of our work is determining the differences between limiting properties in
various models of quantum stochastic walks. In particular, we prove that in the case of …

This work focuses on the study of quantum stochastic walks, which are a generalization of
coherent, ie unitary quantum walks. Our main goal is to present a measure of a coherence of …

The radical pair (RP) based compass is considered as one of the principal models of avian
magnetoreception. Different from the conventional approach where the sensitivity of RP …

Here we show that a coherent random walk in a perfectly periodic chain of bosonic modes
with designed loss can exhibit a variety of different anomalous transfer regimes in …

Many animals display sensitivity to external magnetic field, but it is only in the simplest
organisms that the sensing mechanism is understood. Here we report on behavioural …
