Stability in the determination of the coefficients for coupled relativistic Schrödinger system
Nitesh Kumar, Parveen Kumar, Tanmay Sarkar
In this article, we prove a stability result for the identification of the coefficients appearing in a coupled relativistic Schrödinger system posed on a bounded domain of $\mathbb…
A partial data coefficient identification inverse problem for a semilinear damped wave operator
Mandeep Kumar, Parveen Kumar, Manmohan Vashisth
This manuscript deals with a coefficient identification inverse problem for a semilinear damped wave operator in a bounded domain of . We establish the…
Stable determination of time-dependent coefficients in a reaction-diffusion-convection system
Rahul Bhardwaj, Parveen Kumar
In this manuscript, we investigate an inverse boundary value problem for a reaction-diffusion-convection system in a bounded domain of , . We aim to obta…
Reconstruction of time-dependent coefficients in a semilinear dynamical Schr{ö}dinger equation
Parveen Kumar, Gen Nakamura, Manmohan Vashisth
In the present manuscript, we study an inverse problem related to a semilinear dynamical Schr{ö}dinger equation with lower order terms, in a bounded domain of $\Rb^{1+n},n\geq 2$.…
Interference of local-measurement histories
Parveen Kumar, Igor V. Gornyi, Yuval Gefen
The evolution of a quantum system comprises two fundamental processes--continuous unitary dynamics and stochastic measurement-induced jumps. The latter are often viewed as a source…
Violations of the Leggett-Garg inequality in Hybrid Liouvillian Dynamics: The Nonlinear Role of Detector Efficiency
Sourav Paul, Parveen Kumar, Sourin Das
Violations of the Leggett-Garg inequality (LGI) up to its algebraic bound under non-Hermitian dynamics are well established theoretically. Here, we demonstrate that such extreme vi…
