“…Drift-diffusion can be realized experimentally, e.g., with a colloidal particle in a flow chamber. Such setup was recently used as part of an experimental demonstration of an information machine [58]. There, a barrier made of light was used to prevent the particle from being carried away by the flow, but light can also be used to trap and manipulate the particle.…”

First-passage processes can be divided in two classes: those that are accelerated by the introduction of restart and those that display an opposite response. In physical systems, a transition between the two classes may occur as governing parameters are varied to cross a universal tipping point. However, a fully tractable model system to teach us how this transition unfolds is still lacking. To bridge this gap, we quantify the effect of stochastic restart on the first-passage time of a drift-diffusion process to an absorbing boundary. There, we find that the transition is governed by the Péclet number (Pe) -the ratio between the rates of advective and diffusive transport. When Pe > 1 the process is drift-controlled and restart can only hinder its completion. In contrast, when 0 ≤ Pe < 1 the process is diffusion-controlled and restart can speed-up its completion by a factor of ∼ 1/Pe. Such speedup occurs when the process is restarted at an optimal rate r r 0 (1 − Pe), where r 0 stands for the optimal restart rate in the pure-diffusion limit. The transition considered herein stands at the core of restart phenomena and is relevant to a large variety of processes that are driven to completion in the presence of noise. Each of these processes has unique characteristics, but our analysis reveals that the restart transition resembles other phase transitions -some of its central features are completely generic. arXiv:1811.08239v4 [cond-mat.stat-mech]

“…This remains an interesting open question. The same issue arises in many other examples of multiple measurements under repeated feedback control [32][33][34][35] One of the most relevant results in [1] is that )*+ in Eq.

In a recent paper we have introduced a continuous version of the Maxwell demon (CMD) that is capable of extracting large amounts of work per cycle by repeated measurements of the state of the system [1]. Here we underline its main features such as the role played by the Landauer limit in the average extracted work, the continuous character of the measurement process and the differences between our continuous Maxwell demon and an autonomous Maxwell demon.We demonstrate the reversal of Landauer's inequality depending on the thermodynamical and mechanical stability of the work extracting substance. We also emphasize the robustness of the Shannon definition of the informationcontent of the stored sequences in the limit where work extraction is maximal and fueled by the large information-content of rare events.

“…Also, various models for 'Maxwell's demon' type information engines, capable of extracting work from a single heat bath by utilizing information about the microscopic state of the system, were developed [17,18,19,20,21]. Recent technological advances in the active control and precision measurement of small fluctuating systems allowed the experimental realization of information engines in classical systems using colloidal particles [22,23,24,25,26,27,28], a single DNA hairpin [29], a single electron box [30], and a photodetector [31]; and in quantum systems using a superconducting qubit [32]. Consequently, generalized fluctuation theorems and several fundamental principles of information thermodynamics were verified experimentally [22,23,26,32,33,34,35].…”

Recent theoretical developments in information thermodynamics elucidated the link between the acquired information and the entropy production through measurement and feedback control by generalizing the fluctuation theorems and the second law of thermodynamics. We summarize here our recent experimental studies based on the colloidal system that have been conducted to test the theoretical findings of information thermodynamics. In particular, we present the design principles of error-free and noisy information engines consisting of a colloidal particle in an optical trap that is capable of performing nearly error-free measurement and ultrafast feedback control. Our perspectives on future experimental studies are also presented.
