We review some aspects of the implementation of spacetime symmetries in noncommutative
field theories, emphasizing their origin in string theory and how they may be used to …

We study entanglement entropy (EE) in conformal field theories (CFTs) in Minkowski space
with a planar boundary or with a planar defect of any codimension. In any such boundary …

The problem of finding a holographic CFT dual to string theory on AdS3× S3× S3× S1 is
examined in depth. This background supports a large superconformal symmetry. While in …

This is an introduction to the microscopic techniques of non-rational bulk and boundary
conformal field theory which are needed to describe strings moving in non-compact curved …

We study the fusion of conformal interfaces in the c= 1 conformal field theory. We uncover an
elegant structure reminiscent of that of black holes in supersymmetric theories. The role of …

A bstract It was recently observed that boundary correlators of the elementary scalar field of
the Liouville theory on AdS 2 background are the same (up to a non-trivial proportionality …

A bstract AdS 3 string theory in the stringy regime k=(R AdS/ℓ s) 2< 1 provides a laboratory
for the study of holography in which both sides of AdS/CFT duality are under fairly good …

A bstract We show that the geometric interpretation of D-branes in WZW models as twisted
conjugacy classes persists in the λ-deformed theory. We obtain such configurations by …

We study a model of densely packed self-avoiding loops on the annulus, related to the
Temperley–Lieb algebra with an extra idempotent boundary generator. Four different …

This is an expository paper which aims at explaining a physical point of view on the K-
theoretic classification of D-branes. We combine ideas of renormalization group flows …
