Quantum dynamics of spin-J particles in static and rotating magnetic fields: Entanglement resonances and kinks
Nargis Sultana, Siddharth Seetharaman, Rejish Nath
We examine the quantum dynamics of both a single spin-J particle and a pair of spin-J particles in the presence of static and rotating magnetic fields, which can be important for q…

Properties of Krylov state complexity in qubit dynamics
Siddharth Seetharaman, Chetanya Singh, Rejish Nath
We analyze the properties of Krylov state complexity in qubit dynamics, considering a single qubit and a qubit pair. A geometrical picture of the Krylov complexity is discussed for…
