Entanglement Entropy of 3-d Conformal Gauge Theories with Many Flavors
Igor R. Klebanov, Silviu S. Pufu, Subir Sachdev +1
Three-dimensional conformal field theories (CFTs) of deconfined gauge fields coupled to gapless flavors of fermionic and bosonic matter describe quantum critical points of condense…
Renyi Entropies for Free Field Theories
Igor R. Klebanov, Silviu S. Pufu, Subir Sachdev +1
Renyi entropies S_q are useful measures of quantum entanglement; they can be calculated from traces of the reduced density matrix raised to power q, with q>=0. For (d+1)-dimensiona…
F-Theorem without Supersymmetry
Igor R. Klebanov, Silviu S. Pufu, Benjamin R. Safdi
The conjectured F-theorem for three-dimensional field theories states that the finite part of the free energy on S^3 decreases along RG trajectories and is stationary at the fixed…
Towards the F-Theorem: N=2 Field Theories on the Three-Sphere
Daniel L. Jafferis, Igor R. Klebanov, Silviu S. Pufu +1
For 3-dimensional field theories with {\cal N}=2 supersymmetry the Euclidean path integrals on the three-sphere can be calculated using the method of localization; they reduce to c…
