The S-matrix and boundary correlators in flat space
Diksha Jain, Suman Kundu, Shiraz Minwalla +3
We consider the path integral of a quantum field theory in Minkowski spacetime with fixed boundary values (for the elementary fields) on asymptotic boundaries. We define and study…
Canonical Purification and the Quantum Extremal Shock
Onkar Parrikar, Vivek Singh
We study the canonical purification (with respect to one of the parties) of pure, bi-partite states obtained by turning on sources in the Euclidean path integral. In holographic co…
Condensation of Lattice Defects and Melting Transitions in Quantum Hall phases
Gil Young Cho, Onkar Parrikar, Yizhi You +2
Motivated by recent progress in understanding the interplay between lattice and electronic topological phases, we consider quantum-melting transitions of {\it weak} quantum liquid…
Torsion, Parity-odd Response and Anomalies in Topological States
Onkar Parrikar, Taylor L. Hughes, Robert G. Leigh
We study the response of a class of topological systems to electromagnetic and gravitational sources, including torsion and curvature. By using the technology of anomaly polynomial…
The Exact Renormalization Group and Higher-spin Holography
Robert G. Leigh, Onkar Parrikar, Alexander B. Weiss
In this paper, we revisit scalar field theories in space-time dimensions possessing global symmetry. Following our recent work arXiv:1402.1430v2, we consider the generat…
