Tuning the phase diagram of a Rosenzweig-Porter model with fractal disorder
Madhumita Sarkar, Roopayan Ghosh, Ivan M. Khaymovich
Rosenzweig-Porter (RP) model has garnered much attention in the last decade, as it is a simple analytically tractable model showing both ergodic--nonergodic extended and Anderson l…
Quantum order-by-disorder induced phase transition in Rydberg ladders with staggered detuning
Madhumita Sarkar, Mainak Pal, Arnab Sen +1
atoms are known to have long-lived Rydberg excited states with controllable excitation amplitude (detuning) and strong repulsive van der Waals interaction $V_{{\bf…
Signatures of multifractality in a periodically driven interacting Aubry-André model
Madhumita Sarkar, Roopayan Ghosh, Arnab Sen +1
We study the many-body localization (MBL) transition of Floquet eigenstates in a driven, interacting fermionic chain with an incommensurate Aubry-André potential and a time-periodi…
Mobility edge and multifractality in a periodically driven Aubry-André model
Madhumita Sarkar, Roopayan Ghosh, Arnab Sen +1
We study the localization-delocalization transition of Floquet eigenstates in a driven fermionic chain with an incommensurate Aubry-André potential and a hopping amplitude which is…
Dynamical Transition for a class of integrable models coupled to a bath
Madhumita Sarkar, K. Sengupta
We study the dynamics of correlation functions of a class of dimensional integrable models coupled linearly to a fermionic or bosonic bath in the presence of a periodic drive w…
Energy and Effective Mass Dependence of Electron Tunnelling Through Multiple Quantum barriers in Different Heterostructures
Jatindranath Gain, Madhumita Das Sarkar, Sudakshina Kundu
Tunneling of electrons through the barriers in heterostructures has been studied, within unified transfer matrix approach. The effect of barrier width on the transmission coefficie…
