Quantum Work Extraction via Conditional Spatial Displacements
Necati Çelik
We propose a protocol for extracting work from a coherent quantum battery state by exploiting measurement-assisted feedback mediated by a continuous-variable pointer. The scheme re…

Spectral-Gap Bounds and Timescales for Purity Loss in Hamiltonian--Pointer Interactions
Orhan Amirov, Necati Çelik
We investigate the purity dynamics of a quantum system coupled to a continuous-variable pointer through a von Neumann-type interaction Hamiltonian of the form $\hat H_{\mathrm{int}…

A New Quantum Interferometric Protocol Using Spin-Dependent Displacements
Necati Celik, Songul Akbulut Ozen, Burhan Engin
We propose a quantum interferometric protocol that leverages spin-dependent spatial displacements to enable high-precision parameter estimation beyond classical limits. By inducing…
