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…

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…
