Decoherence induced by a dynamic spin environment (I): The universal regime [PDF]

, 2007
This article analyzes the decoherence induced on a single qubit by the interaction with a spin chain with nontrivial internal dynamics (XY-type interactions). The aim of the paper is to study the existence and properties of the so-called universal regime,

Attributed Network Embedding for Learning in a Dynamic Environment

, 2018
Network embedding leverages the node proximity manifested to learn a low-dimensional node vector representation for each node in the network. The learned embeddings could advance various learning tasks such as node classification, network clustering, and

Prevalence and mobility of integrative and conjugative elements within a Streptomyces natural population

Frontiers in Microbiology, 2022
Horizontal Gene Transfer (HGT) is a powerful force generating genomic diversity in bacterial populations. HGT in Streptomyces is in large part driven by conjugation thanks to plasmids, Integrative and Conjugative elements (ICEs) and Actinomycete ICEs ...

Excitation Dynamics in Chain-Mapped Environments [PDF]

Entropy, 2020
The chain mapping of structured environments is a most powerful tool for the simulation of open quantum system dynamics. Once the environmental bosonic or fermionic degrees of freedom are unitarily rearranged into a one dimensional structure, the full power of Density Matrix Renormalization Group (DMRG) can be exploited.
