Entanglement entropy inequalities in BCFT by holography

چکیده

We study entanglement entropy inequalities in boundary conformal field theory (BCFT) by holographic correspondence. By carefully classifying all the configurations for different phases, we prove strong subadditiviy and monogamy of mutual information BCFT at both zero finite temperatures

Topological Entanglement Entropy and Holography

We study the entanglement entropy in confining theories with gravity duals using the holographic prescription of Ryu and Takayanagi. The entanglement entropy between a region and its complement is proportional to the minimal area of a bulk hypersurface ending on their border. We consider a disk in 2+1 dimensions and a ball in 3+1 dimensions and find in both cases two types of bulk hypersurfaces...

Thermal corrections to entanglement entropy from holography

We use holographic techniques to calculate the first thermal correction to the entanglement entropy of a cap-like region of a CFT defined on a sphere, successfully reproducing the field theory result. Since this is an order-one correction to the entropy in the large-N expansion, quantum corrections to the holographic entanglement entropy formula are essential. The bulk calculation is made tract...

Identifying topological order by entanglement entropy

Topological phases are unique states of matter that incorporate long-range quantum entanglement and host exotic excitations with fractional quantum statistics. Here we report a practical method to identify topological phases in arbitrary realistic models by accurately calculating the topological entanglement entropy using the density matrix renormalization group (DMRG). We argue that the DMRG a...

Bell inequalities and entanglement

We discuss general Bell inequalities for bipartite and multipartite systems, emphasizing the connection with convex geometry on the mathematical side, and the communication aspects on the physical side. Known results on families of generalized Bell inequalities are summarized. We investigate maximal violations of Bell inequalities as well as states not violating (certain) Bell inequalities. Fin...

Entanglement and Bell’s Inequalities

Our goal for this experiment was to demonstrate violation of Bell’s inequalties. This was accomplished by producing two polarization entangled photons via spontaneous parametric down-conversion using two type 1 beta barium borate crystals. With polarizers placed in front of two avalanche photodiodes, we observed how the alignment of the polarizers affected the number of observed photon pairs co...
