Dissipation induced Majarona - and -modes in a driven Rashba nanowire
Koustabh Gogoi, Tanay Nag, Arnob Kumar Ghosh
Periodic drive is an intriguing way of creating topological phases in a non-topological setup. However, most systems are often studied as a closed system, despite being always in c…
Quantum state transfer and maximal entanglement between distant qubits using a minimal quasicrystal pump
Arnob Kumar Ghosh, Rubén Seoane Souto, Vahid Azimi-Mousolou +2
Coherent quantum state transfer over macroscopic distances between non-neighboring elements in quantum circuits is a crucial component to increase connectivity and simplify quantum…
Multi higher-order Dirac and nodal line semimetals
Amartya Pal, Arnob Kumar Ghosh
In recent years, there has been a surge of interest in exploring higher-order topology and their semi-metallic counterparts, particularly in the context of Dirac, Weyl, and nodal l…
Local and energy-resolved topological invariants for Floquet systems
Arnob Kumar Ghosh, Rodrigo Arouca, Annica M. Black-Schaffer
Periodically driven systems offer a perfect breeding ground for out-of-equilibrium engineering of topological boundary states at zero energy (-mode), as well as finite energy ($…
