The ability to charge your electric vehicle at home appears to prompt the switch to dynamic energy prices. That's what a survey of Dutch #EV drivers indicates: Of those able to charge their EV at home, 41% are on a dynamic tariff, with a further 34% wanting to switch.

Dark Signals in the Brain: Augment Brain Network Dynamics to the Complex-valued Field
Recordings of brain activity, such as functional MRI (fMRI), provide low-dimensional, indirect observations of neural dynamics evolving in high-dimensional, unobservable spaces. Embedding observed brain dynamics into a higher-dimensional representation may help reveal functional organization, but precisely how remains unclear. Hamiltonian mechanics suggests that, by introducing an additional dimension of conjugate momenta, the dynamical behaviour of a conservative system can be formulated in a …

Infinite-Dimensional Stochastic Differential Equations and Diffusion Dynamics of Coulomb Random Point Fields
We consider the stochastic dynamics of infinite particle systems in $\mathbb{R}^d$ interacting through the $d$-dimensional Coulomb potential. For arbitrary inverse temperature $β>0$ and all dimensions $d\ge2$, we construct solutions to the associated infinite-dimensional stochastic differential equations (ISDEs). Our main results establish the existence of strong solutions and their pathwise uniqueness. The resulting labeled process is an $(\mathbb{R}^d)^N$-valued diffusion with no invariant m…

U-generating system dynamics with a product state using local operations
A quantum system may undergo undesired dynamics if it is already correlated with its environment before global unitary evolution takes place. To mitigate these effects, we apply local operations on the system of interest prior to the global evolution. This ensures that a specific dynamics-matching condition is satisfied - namely, that the system's dynamics can be U-generated starting from an initial product state. We review two strategies for achieving this: local measurements and local unitari…

Reducing Spatial and Temporal Dimensionality in the Multidimensional Caldeira-Leggett Model
Focusing on the real-time dynamics of the reduced density matrix of the multidimensional Caldeira-Leggett model, several techniques are adopted in this paper to reduce the spatial and temporal dimensionality, combined into an efficient algorithm. From a spatial perspective, an equivalent formulation of the Dyson series is presented. With the aid of a low-rank approximation, the spatial dimensionality of open quantum system simulations is halved. From a temporal perspective, the frozen Gaussian …
