Quantum light-matter interactions in structured waveguides
Rupak Bag, Dibyendu Roy
We explore special features of quantum light-matter interactions inside structured waveguides due to their finite bandwidth, band edges, and non-trivial topological properties. We…
Fragile object transportation by a multi-robot system in an unknown environment using a semi-decentralized control approach
Dibyendu Roy, Sreejeet Maity, Madhubanti Maitra +1
In this paper, we introduce a semi-decentralized control technique for a swarm of robots transporting a fragile object to a destination in an uncertain occluded environment.The pro…
Single photons versus coherent state input in waveguide quantum electrodynamics: light scattering, Kerr and cross-Kerr effect
Athul Vinu, Dibyendu Roy
While the theoretical studies in waveguide quantum electrodynamics predominate with single-photon and two-photon Fock state (photon number states) input, the experiments are primar…
Spectral form factor in a minimal bosonic model of many-body quantum chaos
Dibyendu Roy, Divij Mishra, Tomaž Prosen
We study spectral form factor in periodically-kicked bosonic chains. We consider a family of models where a Hamiltonian with the terms diagonal in the Fock space basis, including r…
Topology of multipartite non-Hermitian one-dimensional systems
Ritu Nehra, Dibyendu Roy
The multipartite non-Hermitian Su-Schrieffer-Heeger model is explored as a prototypical example of one-dimensional systems with several sublattice sites for unveiling intriguing in…
Self-stabilization of light sails by damped internal degrees of freedom
M. Z. Rafat, Holger R. Dullin, Boris T. Kuhlmey +7
We consider the motion of a light sail that is accelerated by a powerful laser beam. We derive the equations of motion for two proof-of-concept sail designs with damped internal de…
