Non-Kolmogorov-Arnold-Moser Quantum Sensors for Quantum Parameter Estimation
Naga Dileep Varikuti, Sourav Manna, Athreya Shankar +2
Non-KAM (Kolmogorov-Arnold-Moser) systems, when subjected to weak time-dependent perturbations, exhibit an abrupt transition to classical chaos through the breakdown of invariant p…
Objectivity, basis ambiguity, and the classical simulability of concordant quantum computation
Bishal Kumar Das, Sourav Manna, Vaibhav Madhok
Concordant quantum computations, in which circuits whose register carries zero quantum discord with respect to every subsystem at every step, contain neither entanglement nor any o…
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 ha…
Half-quantized Hall Plateaus in the Confined Geometry of Graphene
Preeti Pandey, Sourav Manna, Kristiana N. Frei +8
Since the ground-breaking discovery of the quantum Hall effect, half-quantized quantum Hall plateaus have been some of the most studied and sought-after states. Their importance st…
Information acquisition, scrambling, and sensitivity to errors in quantum chaos
Sreeram PG, Abinash Sahu, Naga Dileep Varikuti +3
Signatures of chaos can be understood by studying quantum systems whose classical counterpart is chaotic. However, the concepts of integrability, non-integrability and chaos extend…
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…
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…
Shot noise as a diagnostic in the fractional quantum Hall edge zoo
Sourav Manna, Ankur Das, Yuval Gefen +1
The filling is the simplest paradigmatic example of a fractional quantum Hall state, which contains counter-propagating edge modes. These modes can be either in the unequi…
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…
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…
Full Classification of Transport on an Equilibrated 5/2 Edge via Shot Noise
Sourav Manna, Ankur Das, Moshe Goldstein +1
The nature of the bulk topological order of the 5/2 non-Abelian fractional quantum Hall state and the steady-state of its edge are long-studied questions. The most promising non-Ab…
Topologically distinct atomic insulators
Sanjib Kumar Das, Sourav Manna, Bitan Roy
Topological classification of quantum solids often (if not always) groups all trivial atomic or normal insulators (NIs) into the same featureless family. As we argue here, this is…
