One Plus One Equals Two Ones: On Identity, Aggregation, and Counting
Souvik Ghosh
A childhood observation of Thakur Anukulchandra that "one and one can only be two ones, not simply two" motivates a precise inquiry: what, exactly, is asserted when we pass from tw…
Exploring Topological and Localization Phenomena in SSH Chains under Generalized AAH Modulation: A Computational Approach
Souvik Ghosh, Sayak Roy
The Su-Schrieffer-Heeger (SSH) model serves as a canonical example of a one-dimensional topological insulator, yet its behavior under more complex, realistic conditions remains a f…
Impact of Temporally Correlated Dephasing Noise on the Fidelity of the 2-Qubit Deutsch-Jozsa Algorithm
Souvik Ghosh
Understanding the influence of realistic noise on quantum algorithms is paramount for the advancement of quantum computation. While often modeled as Markovian, environmental noise…
Numerical Investigation of Stub Length Influence on Dispersion Relations and Parity Effect in Aharonov-Bohm Rings
Souvik Ghosh
Aharonov-Bohm (AB) rings with side-attached stubs are model systems for quantum-interference studies in mesoscopic physics. The geometry of such systems, particularly the ratio of…
Inverse Diffusion Approximation for Extraction of Scattering and Absorption Coefficients in Highly Scattering Media
Lingxi Li, Yue Yu, Joanna Borowiec +6
Photon transport through a diffusing slab can be described by the radiative transfer equation (RTE). When the slab is highly scattering and weakly absorbing, the RTE simplifies to…
