Smeared phase transition in the dissipative random quantum Ashkin-Teller model
Pedro S. Farinas, Rajesh Narayanan, José A. Hoyos
We study the effects of dissipation in the phase diagram of the random quantum Ashkin-Teller model by means of a generalization of the strong-disorder renormalization group combine…

Fock space fragmentation in quenches of disordered interacting fermions
Ishita Modak, Rajesh Narayanan, Ferdinand Evers +1
Hilbert space fragmentation, as it is currently investigated, primarily originates from specific kinematic constraints or emergent conservation laws in many-body systems with trans…

Measuring dark state number in the Tavis-Cummings model
L. Theerthagiri, Rajesh Narayanan, R. Ganesh
Quantum mechanics allows for light-matter setups that hold excitations without releasing them as light. Arising from destructive interference processes, they are best seen in a Tav…
