Fractional Conformal Map, Qubit Dynamics and the Leggett-Garg Inequality

Autor: Paul, Sourav, Varma, Anant Vijay, Das, Sourin

Any pure state of a qubit can be geometrically represented as a point on the extended complex plane through stereographic projection. By employing successive conformal maps on the extended complex plane, we can generate an effective discrete-time evo

Autor: Pandey, Vineet, Mishra, Subhendu, Maity, Nikhilesh, Paul, Sourav, B, Abhijith M, Roy, Ajit, Glavin, Nicholas R, Watanabe, Kenji, Taniguchi, Takashi, Singh, Abhishek Kumar, Kochat, Vidya

Publikováno v: ACS Nano 2024

Twisted 2D layered materials have garnered a lot of attention recently as a class of 2D materials whose interlayer interactions and electronic properties are dictated by the relative rotation / twist angle between the adjacent layers. In this work, w

Essential role of quantum speed limit in violation of Leggett-Garg inequality across a PT-transition

Autor: Varma, Anant V., Muldoon, Jacob E., Paul, Sourav, Joglekar, Yogesh N., Das, Sourin

Publikováno v: Phys. Rev. A 108, 032202 (2023)

We study Leggett-Garg inequality (LGI) of a two level system (TLS) undergoing non-Hermitian dynamics governed by a non-linear Bloch equation (derived in J. Phys. A: Math. Theor. 54, 115301 (2021)) across a PT-transition. We present an algebraic ident
