Superspace invariants and 3-point correlators in 3d SCFTs

Aditya Jain, Amin A. Nizami

We use the auxiliary polarization spinor formalism together with superspace techniques to construct a complete and minimal list of 3-point invariant structures in three-dimensional…

Superspace invariants and correlators in 4d superconformal field theories

Aditya Jain, Amin A. Nizami

Using polarization spinor methods in conjunction with the superspace formalism, we construct 3-point superconformal invariants that are used to determine the form of 3-point correl…

Spread complexity and quantum chaos for periodically driven spin chains

Amin A. Nizami, Ankit W. Shrestha

The complexity of quantum states under dynamical evolution can be investigated by studying the spread with time of the state over a pre-defined basis. It is known that this complex…

Krylov construction and complexity for driven quantum systems

Amin A. Nizami, Ankit W. Shrestha

Krylov complexity is an important dynamical quantity with relevance to the study of operator growth and quantum chaos, and has recently been much studied for various time-independe…

Higher spin 3-point functions in 3d CFT using spinor-helicity variables

Sachin Jain, Renjan Rajan John, Abhishek Mehta +2

In this paper we use the spinor-helicity formalism to calculate 3-point functions involving scalar operators and spin- conserved currents in general 3d CFTs. In spinor-helicity…

Double copy structure of parity-violating CFT correlators

Sachin Jain, Renjan Rajan John, Abhishek Mehta +2

We show that general parity-violating 3d conformal field theories show a double copy structure for momentum space 3-point functions of conserved currents, stress tensor and margina…

Momentum space parity-odd CFT 3-point functions

Sachin Jain, Renjan Rajan John, Abhishek Mehta +2

We study the parity-odd sector of 3-point functions comprising of scalar operators and conserved currents in conformal field theories in momentum space. We use momentum space confo…

Quantum chaos measures for Floquet dynamics

Amin A. Nizami

Periodically kicked Floquet systems such as the kicked rotor are a paradigmatic and illustrative simple model of chaos. For non-integrable quantum dynamics there are several diagno…

Thermal out-of-time-order correlators, KMS relations, and spectral functions

Felix M. Haehl, R. Loganayagam, Prithvi Narayan +2

We describe general features of thermal correlation functions in quantum systems, with specific focus on the fluctuation-dissipation type relations implied by the KMS condition. Th…

On Brane Back-Reaction and de Sitter Solutions in Higher-Dimensional Supergravity

C. P. Burgess, Anshuman Maharana, L. van Nierop +2

We argue that the problem of finding lower-dimensional de Sitter solutions to the classical field equations of higher-dimensional supergravity necessarily requires understanding th…
