Adiabatic modulation of driving protocols in periodically driven quantum systems
Ashwin Murali, Tapomoy Guha Sarkar, Jayendra N. Bandyopadhyay
We consider a periodically driven system where the high-frequency driving protocol consists of a sequence of potentials switched on and off at different instants within a period. W…
Phase transition in a Aubry-Andre system with rapidly oscillating magnetic field
Tridev Mishra, Rajath Shashidhara, Tapomoy Guha Sarkar +1
We investigate a variant of the Aubry-André-Harper (AAH) model corresponding to a bosonic optical lattice of ultra cold atoms under an effective oscillatory magnetic field. In the…
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…
Metric deformation and boundary value problems in 2D
Subhasis Panda, Tapomoy Guha Sarkar, S Pratik Khastgir
A new analytical formulation is prescribed to solve the Helmholtz equation in 2D with arbitrary boundary. A suitable diffeomorphism is used to annul the asymmetries in the boundary…
