Synthetic Flat Bands, Hierarchical Topology, and Phase-Fluctuation-Insensitive Quantized Transconductance in Josephson Junctions
Subhadeep Chakraborty, Aabir Mukhopadhyay, Udit Khanna +1
We uncover hierarchy of topological phases within the synthetic Brillouin zone of a three-terminal Josephson junction's (3-TJJ's) Bogoliubov-de Gennes spectrum. We demonstrate that…
Multistability and Self-Trapping in Cavity-Magnonic Dimer
Pooja Kumari Gupta, Amarendra K. Sarma, Subhadeep Chakraborty
We show that a driven-dissipative cavity-magnonic dimer supports multistability with coexisting symmetric and symmetry-broken steady states. The interplay between magnon Kerr nonli…
Quantum signatures of bistability and limit cycle in Kerr-modified cavity magnomechanics
Pooja Kumari Gupta, Subhadeep Chakraborty, Sampreet Kalita +1
We study a Kerr-modified cavity magnomechanical system with a focus on its bistable regime. We identify a distinct parametric condition under which bistability appears, featuring t…
Self-trapping phenomenon, multistability and chaos in open anisotropic Dicke dimer
G. Vivek, Debabrata Mondal, Subhadeep Chakraborty +1
We investigate semiclassical dynamics of a coupled atom-photon interacting system described by a dimer of anisotropic Dicke model in the presence of photon loss, exhibiting a rich…
Robust Majorana bound state in pseudo-spin domain wall of 2-D topological insulator
Subhadeep Chakraborty, Vivekananda Adak, Sourin Das
We investigate helical edge states (HES) emerging at the composite domain wall of spin and pseudo-spin degrees of freedom in a 2-D bulk governed by the Bernevig-Hughes-Zhang Hamilt…
