Tunable Floquet selection rules in a driven Ising chain
Rishi Paresh Joshi, Sanchayan Banerjee, Sneha Narasimha Moorthy +1
We study a periodically driven spin- Ising chain with a nearest-neighbour coupling and longitudinal field while a weak transverse field induces single-spin flips. Through Floq…

Random acceleration noise on Stern-Gerlach Interferometry in a Harmonic Trap
Sneha Narasimha Moorthy, Andrew Geraci, Sougato Bose +1
We analyze decoherence in a one-loop Stern--Gerlach--type matter-wave interferometer for a massive nanoparticle embedded with a nitrogen vacancy (NV)-centered nanodiamond evolving…

Magnetic noise in macroscopic quantum spatial superposition induced by inverted harmonic oscillator potential
Sneha Narasimha Moorthy, Anupam Mazumdar
We investigate a Stern-Gerlach type matter-wave interferometer where an inhomogeneous magnetic field couples to an embedded spin in a nanoparticle to create spatial superpositions.…
