On the Quantum Resolution of Cosmological Singularities using AdS/CFT
, 2012 The AdS/CFT correspondence allows us to map a dynamical cosmology to a dual quantum field theory living on the boundary of spacetime. Specifically, we study a five-dimensional model cosmology in type IIB supergravity, where the dual theory is an unstable

Berry phase in quantum field theory: Diabolical points and boundary phenomena [PDF]
Physical Review B, 2020 We study aspects of Berry phase in gapped many-body quantum systems by means of effective field theory. Once the parameters are promoted to spacetime-dependent background fields, such adiabatic phases are described by Wess-Zumino-Witten (WZW) and similar terms.

Analytic bootstrap for boundary CFT
Journal of High Energy Physics, 2019 We propose a method to analytically solve the bootstrap equation for two point functions in boundary CFT. We consider the analytic structure of the correlator in Lorentzian signature and in particular the discontinuity of bulk and boundary conformal ...

Journal of High Energy Physics, 2020 We analyze a simple example of a holographically dual pair in which we topologically twist both theories. The holography is based on the two-dimensional N = 2 supersymmetric Liouville conformal field theory that defines a unitary bulk quantum ...

Charging up the functional bootstrap
Journal of High Energy Physics, 2021 We revisit the problem of bootstrapping CFT correlators of charged fields. After discussing in detail how bounds for uncharged fields can be recycled to the charged case, we introduce two sets of analytic functional bases for correlators on the line. The

Liouville theory and matrix models: a Wheeler DeWitt perspective
Journal of High Energy Physics, 2020 We analyse the connections between the Wheeler DeWitt approach for two dimensional quantum gravity and holography, focusing mainly in the case of Liouville theory coupled to c = 1 matter.

Conformal bootstrap near the edge
Journal of High Energy Physics, 2021 We propose a bootstrap program for CFTs near intersecting boundaries which form a co-dimension 2 edge. We describe the kinematical setup and show that bulk 1-pt functions and bulk-edge 2-pt functions depend on a non-trivial cross-ratio and on the angle ...
