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
Fock-space fragmentation, as it is currently investigated, primarily originates from specific kinematic constraints or emergent conservation laws in many-body systems with translat…
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…
Spin-basis wavefunctions for the one-dimensional Kitaev model
Alwyn Jose Raja, Rajesh Narayanan, R. Ganesh
Magnetic phases with quantum entanglement are often expressed in terms of parton wavefunctions. Relatively few examples are known where wavefunctions can be directly written down i…
Fermi-Bose crossover using engineered disorder potential
Madhuparna Karmakar, Rajesh Narayanan
We present the first instance of a disorder tuned Fermi-Bose crossover that could be realized in superconducting systems. More specifically, harnessing a non perturbative numerical…
