The AdS/CFT duality maps supersymmetric heavy operators with conformal dimension of the order of the central charge to asymptotically AdS supergravity solutions. We show that by studying the quadratic fluctuations around such backgrounds it is possible to derive the 4-point correlators of two light and two heavy states in the supergravity...

We derive an explicit expression for the 1/c con- tribution to the Virasoro blocks in 2D CFT in the limit of large c with fixed values of the operators' dimensions. We follow the direct approach of orthonormalising, at order 1/c, the space of the Virasoro descendants to obtain the blocks as a series expansion around z = 0. For generic conformal...

We derive the four-point correlators of scalar operators of dimension one in the supergravity limit of the D1D5 CFT holographically dual to string theory on AdS3×S3×M, with M either T4 or K3. We avoid the use of Witten diagrams but deduce our result from a limit of the heavy-heavy-light-light correlators computed in [1], together with several...

We present a formula for the holographic 4-point correlators in AdS3 × S3 involving four single-trace operators of dimension k, k, l, l. As an input we use the super- gravity results for the Heavy-Heavy-Light-Light correlators that can be derived by studying the linear fluctuations around known asymptotically AdS3 × S3 geometries. When the op-...

We study a simple class of correlators with two heavy and two light operators both in the D1D5 CFT and in the dual AdS3 × S3 × T 4 description. On the CFT side we focus on the free orbifold point and discuss how these correlators decompose in terms of conformal blocks, showing that they are determined by protected quantities. On the gravity...

We compute correlators of two heavy and two light operators in the strong coupling and large c limit of the D1D5 CFT which is dual to weakly coupled AdS3 gravity. The light operators have dimension two and are scalar descendants of the chiral primaries considered in arXiv:1705.09250, while the heavy operators belong to an ensemble of...

Introduction. Tenofovir disoproxil fumarate (Viread®) is the only nucleotide reverse transcriptase inhibitor currently approved for the treatment of HIV. It is frequently prescribed not only for its efficacy but also for its decreased side effect profile compared with other nucleotide analogs. In addition, it is now increasingly recognized as a...

In this report, we describe the coexistence of two rare and debated complications of hepatitis C virus (HCV) infection: interstitial nephritis, with associated focal glomerulosclerosis, and autoimmune hepatitis, in a 55-year-old HIV/HCV-coinfected woman. The patient was treated for the immune-mediated manifestations with mycophenolate mofetil,...

We construct an infinite family of smooth asymptotically-flat supergravity solutions that have the same charges and angular momenta as general supersymmetric D1- D5-P black holes, but have no horizon. These solutions resemble the corresponding black hole to arbitrary accuracy outside of the horizon: they have asymptotically flat regions, AdS3 ×...

A changing paradigm of treatment of kidney transplant recipients is a new, wider approach to immunosuppression, which should take into account both antiviral and anticancer effects, in addition to cardiovascular protection. Recent observations suggest that the early introduction of mammalian target of rapamycin inhibitors (mTORi) in association...
