Engineered Dissipation for Thermal-State Tracking Across Quantum Criticality
Saikat Mistry, Dibyajyoti Sahu, Suhas Gangadharaiah
Engineering dissipation has emerged as a powerful strategy for controlling quantum many-body dynamics, complementing purely coherent control for state preparation. However, finite-…
Localization and Transport in a Non-Hermitian Hexagonal Harper Model
Akshey Rajoriya, Dibyajyoti Sahu, Suhas Gangadharaiah +1
We investigate a one-dimensional non-Hermitian hexagonal Harper model with quasiperiodically modulated hopping amplitudes. In the Hermitian limit, the model exhibits metallic, insu…
Noisy Braiding of Majorana Modes: A Comparison of Nanowire Trijunction and Quantum-Dot-Assisted Architectures
Dibyajyoti Sahu, Suhas Gangadharaiah
Majorana zero modes have emerged as one of the most promising platforms for topological quantum computation, since their non-Abelian braiding statistics allow quantum information t…
Anomaly-Induced Hybrid Bulk Electromagnetic Mode in Weyl Semimetals
Subrahmanyam D, Suhas Gangadharaiah, E. G. Mishchenko
Collective modes provide direct fingerprints of quantum matter. We predict a previously unidentified hybrid bulk electromagnetic mode in Weyl semimetals arising from the interplay…
Suppressing excitations using quantum-Brachistochrone and nearest-neighbour interactions
S John Sharon Sandeep, Dibyajyoti Sahu, Suhas Gangadharaiah
We examine excitation suppression in the transverse-field Ising model (TFIM), where finite-time drive across a quantum critical point is assisted by the presence of a time-dependen…
Entanglement entropy as a probe of topological phase transitions
Manish Kumar, Bharadwaj Vedula, Suhas Gangadharaiah +1
Entanglement entropy (EE) provides a powerful probe of quantum phases, yet its role in identifying topological phase transitions in disordered systems remains underexplored. We int…
