Patient-Reported Factors Impacting Memory and Cognition Among Women Currently or Previously Receiving Treatment for Breast Cancer.

Objectives Cognitive impairments associated with cancer and cancer treatments have yet to determine definitive causes, gold-standard assessments, or effective treatments to offset or mitigate symptoms. The purpose of the current study was to determine relationships between women with breast cancer and the negative memory impact of treatment and other factors. Materials and methods This online study included 171 participants receiving at least one type of treatment for breast cancer.

Reversible Phasonic Control of a Quantum Phase Transition in a Quasicrystal.

Periodic driving can tune the quasistatic properties of quantum matter. A well-known example is the dynamical modification of tunneling by an oscillating electric field. Here we show experimentally that driving the phasonic degree of freedom of a cold-atom quasicrystal can continuously tune the effective quasidisorder strength, reversibly toggling a localization-delocalization quantum phase transition.

Minimal quantum heat pump based on high-frequency driving and non-Markovianity.

We propose a minimal setup for a quantum heat pump consisting of two tunnel-coupled quantum dots, each hosting a single level and each being coupled to a different fermionic reservoir. The working principle relies on both non-Markovian system-bath coupling and driving-induced resonant coupling. We describe the system using a reaction-coordinate mapping in combination with Floquet-Born-Markov theory and characterize its performance.
