Witryna23 sie 2024 · In this paper we review the AdS/BCFT proposal of T. Takayanagi for holographic description of systems with boundaries, in particular, boundary conformal field theories (BCFTs). Motivated by better understanding of the proposed duality we employ entanglement entropy as a probe of familiar properties of impurities and … Witryna18 mar 2024 · Impurity contribution to the entropy S imp plotted against temperature T for a Kitaev tetrahedron with Kitaev couplings K = 0.5 and K ′ = 10 − 4, and Kondo coupling J = 0.3. Additional Heisenberg couplings ( J H and J H ′ ) between the sites of the cluster are also introduced such that J H = α K and J H ′ = α K ′ . florida society of the sar
Quantum phase transition of Ising-coupled Kondo impurities
Witryna9 lis 2024 · The entropy or the impurity measure can only take value from 0 to 1 as the probability ranges from 0 to 1 and hence, we do not want the above situation. So, to make the curve and the value of log 2 p i back to zero, we multiply log 2 p i with the probability i.e. with p i itself. Witryna11 lis 2015 · Entanglement Entropy in a Holographic Kondo Model. Johanna Erdmenger, Mario Flory, Carlos Hoyos, Max-Niklas Newrzella, Jackson M. S. Wu. We calculate entanglement and impurity entropies in a recent holographic model of a magnetic impurity interacting with a strongly coupled system. There is an RG flow to … Witryna2 gru 2024 · Entropy is a measure of information that indicates the disorder of the features with the target.
