Exact Solvability and Integrability Signatures in a Periodically Driven Infinite-Range Spin Chain: The Case of Floquet interval
Harshit Sharma, Sashmita Rout, Avadhut V. Purohit +1
We study the signatures of quantum integrability (QI) in a spin chain model, having infinite-range Ising interaction and subjected to a periodic pulse of an external magnetic field…
Study of double kicked top: a classical and quantum perspective
Avadhut V. Purohit, Udaysinh T. Bhosale
We study the double kicked top (DKT), which is an extension of the standard quantum kicked top (QKT) model. The model allows us to study the transition from time-reversal symmetric…
The scalar field and gravity combined variable in ADM theory
Avadhut V Purohit
The canonical theory of gravity together with the scalar field is written as a combined variable theory in ADM form, in the classical and quantum theory. FLRW cosmology is r…
Combined variable field theory in FLRW cosmology
Avadhut Purohit
This work aims to study consequences of \textit{combined variable field theory} developed in [1] by analysing FLRW models of gravity. It shows $Φ_{q \rightarrow 0} \rightarrow \inf…
