Abstract: I'll review a few recent papers that discuss the subject in the title, focusing on results based on AdS/CFT.References:https://arxiv.org/abs/1603.09745http://arxiv.org/pdf/1510.07911.pdfhttps://arxiv.org/abs/1509.06374For background, see:h...

I will describe a method for determining the spins of framed BPS states supported on line defects in 4d N=2 theories of class S. Via the 2d-4d correspondence, this amounts to constructing quantum holonomies on a punctured Riemann surface. The main...

In this talk I will explore the constraints imposed by conformal invariance on defects in a conformal field theory. Correlation function of a conformal defect with a bulk local operator is fixed by conformal invariance up to an overall constant...

Abstract:The replica trick plays an important role in several considerations of condensed matter physics and statistical physics. Recently, it has also played a role in several contexts in high energy theory and holography. We discuss some of the...

I will discuss the recent work on the quantum statistics of particle and loop-like string excitations in 3+1D.It is known that the quantum statistics of particles in 2+1D begets

Some papers:

I would like to discuss the problem of categorification of Chern-Simons partition function on closed 3-manifolds. Physics constructions of Khovanov knot homology, which categorifies Jones polynomial, suggests that there should be a generalization to...

Quantum mechanics is distinguished by three essential features: the Hugeness of Hilbert Space, I.e., the capacity for exponential complexity; the phenomenon of Entanglement; and the duality between Wave Function Collapse and Everett's
