Entanglement-optimal trajectories of many-body quantum Markov processes
<p>We develop a novel approach aimed at solving the equations of motion of open quantum many-body systems. It is based on a combination of generalized wave function trajectories and matrix product states. We introduce an adaptive quantum stochastic propagator, which minimizes the expected entanglement in the many-body quantum state, thus minimizing the computational cost of the matrix product state representation of each trajectory. We illustrate this approach on the example of a one-dimensional open Brownian circuit. We show that this model displays an entanglement phase transition between area and volume law when changing between different propagators and that our method autonomously finds an efficiently representable area law unraveling.</p>
Quantum trajectory entanglement in various unravelings of Markovian dynamics
<p>The cost of classical simulations of quantum many-body dynamics is often determined by the amount of entanglement in the system. In this paper, we study entanglement in stochastic quantum trajectory approaches that solve master equations describing open quantum system dynamics. First, we introduce and compare adaptive trajectory unravelings of master equations. Specifically, building on Ref. [Phys. Rev. Lett. 128, 243601 (2022)], we study several greedy algorithms that generate trajectories with a low average entanglement entropy. Second, we consider various conventional unravelings of a one-dimensional open random Brownian circuit and locate the transition points from area- to volume-law-entangled trajectories. Third, we compare various trajectory unravelings using matrix product states with a direct integration of the master equation using matrix product operators. We provide concrete examples of dynamics, for which the simulation cost of stochastic trajectories is exponentially smaller than the one of matrix product operators.</p>

Plant species and water chemistry data for "Inference of future bog succession trajectory from spatial chronosequence of changing aapa mires"
<p>These files consist of whole plant species and water chemistry data examined in our paper "Inference of future bog succession trajectory from spatial chronosequence of changing aapa mires" (Ecology and Evolution). Species data sets for phytosociological relevés and nested subplots (size of 0.25 m<sup>2</sup>) consist of abundances of all vascular plant, bryophyte, and lichen species in the studied fen, transition, and bog zones of boreal aapa mires. Subplot data includes groupings of species into aerenchymatous and non-aerenchymatous species, and into shallow- and deep-rooted aerenchymatous species. Water chemistry data consist of pH and concentrations of dissolved organic carbon (DOC), Ca, Mg, Fe, Al, Si, and Mn, as well as water-table depth (WTD) for each sampling point.</p>
