Generic tests of CP-violation in high- multi-lepton signals at the LHC and beyond
Yoav Afik, Shaouly Bar-Shalom, Kuntal Pal +2
We introduce a modification to the standard expression for tree-level CP-violation in scattering processes at the LHC, which is important when the initial state in not self-conjuga…
Associated production of Higgs and single top at the LHC in presence of the SMEFT operators
Subhaditya Bhattacharya, Sanjoy Biswas, Kuntal Pal +1
We analyse the single top production in association with the Higgs at the Large Hadron Collider (LHC) using Standard Model (SM) effective operators upto dimension six. We show that…
Conformal Fisher information metric with torsion
Kunal Pal, Kuntal Pal, Tapobrata Sarkar
We consider torsion in parameter manifolds that arises via conformal transformations of the Fisher information metric, and define it for information geometry of a wide class of phy…
Time evolution of spread complexity in quenched Lipkin-Meshkov-Glick model
Mir Afrasiar, Jaydeep Kumar Basak, Bidyut Dey +2
We use the spread complexity of a time evolved state after a sudden quantum quench in the Lipkin-Meshkov-Glick (LMG) model prepared in the ground state as a probe of quantum phase…
Evolution of circuit complexity in a harmonic chain under multiple quenches
Kuntal Pal, Kunal Pal, Ankit Gill +1
We study Nielsen's circuit complexity in a periodic harmonic oscillator chain, under single and multiple quenches. In a multiple quench scenario, it is shown that the complexity sh…
Regularising the JNW and JMN naked singularities
Kunal Pal, Kuntal Pal, Pratim Roy +1
We extend the method of Simpson and Visser (SV) of regularising a black hole spacetime, to cases where the initial metric represents a globally naked singularity. We choose two par…
Complexity in the Lipkin-Meshkov-Glick Model
Kunal Pal, Kuntal Pal, Tapobrata Sarkar
We study complexity in a spin system with infinite range interaction, via the paradigmatic Lipkin-Meshkov-Glick model, in the thermodynamic limit. Exact expressions for the Nielsen…
