Complexity and Entanglement: From quantum gravity to many-body systems
In recent years, complexity and entanglement have emerged as two fundamental computational measures and played a significant role in shaping our understanding of various phenomena, from the geometric nature of quantum ... -
Conformal Bootstrap : Old and New
(2018-05-25)Conformal Field Theories (CFT) are Quantum Field Theories characterized by enhanced (conformal) symmetries. They are interesting to Theoretical Physicists because they occur at critical points in phase transitions of various ... -
Explorations in the Space of S-Matrices
S-matrix is one of the fundamental observables of the quantum theory of relativistic particles. The quantum dynamics of relativistic particles can be abstractly understood in terms of S-matrix bypassing a Lagrangian ... -
Lessons for Conformal Field Theories from Bootstrap and Holography
(2018-02-06)The work done in this thesis includes an exploration of both the conformal field theory techniques and holographic techniques of the Gauge/Gravity duality. From the field theory, we have analyzed the analytical aspects of ... -
Lessons for Gravity from Entanglement
One of the recent fundamental developments in theoretical high energy physics is the AdS/CFT correspondence [1, 2, 3, 4] which posits a relationship between Quantum Field Theories (QFT) in a given dimension and String ... -
New tools to constrain EFTs and CFTs
In this thesis, we develop new methods for the S matrix bootstrap in the context of 2-2 scattering amplitudes and four-point correlators in conformal field theories (CFTs). For 2-2 scattering in quantum field theories, ... -
Understanding Conformal Field Theory in Mellin Space
In the last decade, there has been tremendous progress in understanding conformal eld theories in more than two space-time dimensions. The numerical bootstrap framework has been pushed to a very advanced level of ...
