Flat bands and entanglement in the Kitaev ladder
Ritu Nehra, Devendra Singh Bhakuni, Ajith Ramachandran +1
We report the existence of \emph{flat bands} in a p-wave superconducting Kitaev ladder. We identify two sets of parameters for which the Kitaev ladder sustains flat bands. These fl…
Quantum entanglement and transport in non-equilibrium interacting double-dot setup: The curious role of degeneracy
Anirban Dey, Devendra Singh Bhakuni, Bijay Kumar Agarwalla +1
We study quantum entanglement and its relation to transport in a non-equilibrium interacting double dot system connected to electronic baths. The dynamical properties in the non-in…
Enhancement of crossed Andreev reflection in a Kitaev ladder connected to normal metal leads
Ritu Nehra, Devendra Singh Bhakuni, Auditya Sharma +1
We study nonlocal transport in a two-leg Kitaev ladder connected to two normal metals. The coupling between the two legs of the ladder when the legs are maintained at a (large) sup…
Characteristic length scales from entanglement dynamics in electric-field-driven tight-binding chains
Devendra Singh Bhakuni, Auditya Sharma
We study entanglement dynamics in the nearest-neighbour fermionic chain that is subjected to both DC and AC electric fields. The dynamics gives the well known Bloch oscillations in…
Landauer current and mutual information in a bosonic quantum dot
Hrushikesh Shashikant Sable, Devendra Singh Bhakuni, Auditya Sharma
We study the quantum transport of bosons through a quantum dot coupled to two macroscopic heat baths and , held at fixed temperatures and respectively. We ma…
Many-body entanglement in a topological chiral ladder
Ritu Nehra, Devendra Singh Bhakuni, Suhas Gangadharaiah +1
We find that the topological phase transition in a chiral ladder is characterized by dramatic signatures in many body entanglement entropy between the legs, close to half-filling.…
