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…
Optimal Thermalization under Indefinite Causal Order with Identical and Asymmetric Baths
Neeraj Sharma, Parveen Kumar
Indefinite causal order (ICO), in which the order of quantum operations is placed in a coherent superposition, has been demonstrated to enhance various information-processing tasks…
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…
Gradually opening Schrödinger's box reveals a cascade of sharp dynamical transitions
Barkay Guttel, Danielle Gov, Noam Netzer +9
Quantum mechanics predicts that unobserved systems may exist in a superposition of states, yet measurement produces definite outcomes, a tension at the heart of the quantum-to-clas…
