Experimentally Motivated Order of Length Scales Affect Shot Noise
Sourav Manna, Ankur Das
Shot noise at a conductance plateau in a quantum point contact (QPC) can be explained by considering equilibrations at the quantum Hall edges. The indication from recent experiment…
Absence of quantum Darwinism as a resource in secure quantum communication and computation
Bishal Kumar Das, Sourav Manna, Vaibhav Madhok
The emergence of classical world from underlying quantum mechanics is characterized by not only vanishing quantum correlations but also an unfolding of objectivity also known as qu…
Multiple Mechanisms for Emerging Conductance Plateaus in Fractional Quantum Hall States
Sourav Manna, Ankur Das, Yuval Gefen +1
Two-terminal conductance quantization in the context of quantum Hall (QH) physics is intimately related to the current carried by a discrete number of chiral edge modes. Upon pinch…
Half-integer thermal conductance in the absence of Majorana mode
Ujjal Roy, Sourav Manna, Souvik Chakraborty +6
Considering a range of candidate quantum phases of matter, half-integer thermal conductance () is believed to be an unambiguous evidence of non-Abelian states. It h…
Dynamic mass generation on two-dimensional electronic hyperbolic lattices
Noble Gluscevich, Abhisek Samanta, Sourav Manna +1
Free electrons hopping on hyperbolic lattices embedded on a negatively curved space can foster (a) Dirac liquids, (b) Fermi liquids, and (c) flat bands, respectively characterized…
Entangling power, gate typicality, and measurement-induced phase transitions
Sourav Manna, Vaibhav Madhok, Arul Lakshminarayan
When subject to a non-local unitary evolution, qubits in a quantum circuit become increasingly entangled. Conversely, measurements applied to individual qubits lead to their disent…
