Anomalous Aharonov-Bohm Interference in the Presence of Edge Reconstruction
Sourav Biswas, Hemanta Kumar Kundu, Rajarshi Bhattacharyya +2
Interferometry is a vital tool for studying fundamental features in the quantum Hall effect (QHE). For instance, Aharonov-Bohm (AB) interference in a quantum Hall interferometer ca…
Electron Pairing of Interfering Interface-Based Edge Modes
Sourav Biswas, Hemanta Kumar Kundu, Vladimir Umansky +1
The remarkable Cooper-like pairing phenomenon in the Aharonov-Bohm interference of a Fabry-Perot interferometer (FPI)operating in the integer quantum Hall regimerem…
Operator correlations in a quenched non-Hermitian Luttinger liquid
Ashutosh Dubey, Sourav Biswas, Arijit Kundu
We study operator correlations of a spinful Luttinger liquid after introducing a non-Hermitian interaction quench, yielding supersonic modes and dominant superconducting correlatio…
Two-channel Kondo problem in coupled interacting helical liquids
Sourav Biswas, Alessandro De Martino, Sumathi Rao +1
We study the two-channel Kondo problem in the context of two interacting helical liquids coupled to a spin- magnetic impurity. We show that the interactions between the tw…
