A bstract We study the temporal evolution of circuit complexity after local quench where two harmonic chains are suddenly joined, choosing initial state as reference state. discuss numerical results for entire chain and subsystem a block consecutive sites, obtained by exploiting Fisher information geometry covariance matrices. The qualitative behaviour evolutions depends on whether joining poin...

Qualitative simulation (QS) is an area of artificial intelligence that represent continuos and discrete aspects like space, time and quantity with little information, and makes inferences using symbolic data to represent physical quantities. Tradicionally, QS uses a global statebased representation to represent the behavior of the system. To qualitative simulate a system, some initial values ar...

Introduction Sulfur is required for the biosynthesis of several essential compounds like amino acids (cysteine and methionine), vitamins (biotin, thiamin), and prosthetic groups (Fe-S clusters) in all organisms. In order to synthesize these compounds, the sulfur has usually to be in a reduced state, most commonly as (hydrogen) sulfide. In the absence of an environmental supply of reduced sulfur...

By partitioning the electron density into subsystem contributions, the Frozen Density Embedding (FDE) formulation of subsystem Density Functional Theory (DFT) has recently emerged as a powerful tool for reducing the computational scaling of Kohn-Sham DFT. To date, however, FDE has been employed to molecular systems only. Periodic systems, such as metals, semiconductors, and other crystalline so...
