Study of entanglement and phase transitions in the coupled top systems with standard and nonstandard symmetries
Rashmi Jangid Sharma, Jayendra N. Bandyopadhyay
We study classical and quantum versions of a coupled top system in the absence and the presence of nonlinear torsion in the individual top. The model without the torsion and couple…

Self-similar spectrum in effective time independent Hamiltonians for kicked systems
Rashmi Jangid Sharma, Jayendra N. Bandyopadhyay, Tapomoy Guha Sarkar
We study multifractal properties in the spectrum of effective time-independent Hamiltonians obtained using a perturbative method for a class of delta-kicked systems. The evolution…
