Optimal Quench for Distance-Independent Entanglement and Maximal Block Entropy

Autor: Alkurtass, Bedoor, Banchi, Leonardo, Bose, Sougato

Publikováno v: Phys. Rev. A 90, 042304 (2014)

We optimize a quantum walk of multiple fermions following a quench in a spin chain to generate near ideal resources for quantum networking. We first prove an useful theorem mapping the correlations evolved from specific quenches to the apparently unr

Block entropy for Kitaev-type spin chains in a transverse field

Autor: Subrahmanyam, V.

Publikováno v: Phys. Rev. A 88, 032315 (2013)

Block entanglement entropy in the ground state of a quantum spin chain is investigated. The spins have Kitaev-type nearest-neighbor interaction, of strength J_x or J_y, through either x or y components of the spins on alternating bonds, along with a

Application of Unit Time Block Entropy to Fetal Distress Heart Rate

Autor: Lee, U. C., Kim, S.

Recently, multiple time scale characteristics of heart dynamics have received much attention for distinguishing healthy and pathologic cardiac systems. Despite structural peculiarities of the fetal cardiovascular system, the fetal heart rate(FHR) dis

A Study of Fractality and Long-Range Order in the Distribution of Transposable Elements in Eukaryotic Genomes Using the Scaling Properties of Block Entropy and Box-Counting

Autor: Labrini Athanasopoulou, Diamantis Sellis, Yannis Almirantis

Publikováno v: Entropy, Vol 16, Iss 4, Pp 1860-1882 (2014)

Repeats or Transposable Elements (TEs) are highly repeated sequence stretches, present in virtually all eukaryotic genomes. We explore the distribution of representative TEs from all major classes in entire chromosomes across various organisms. We em
