At the limits of criticality-based quantum metrology: apparent super-Heisenberg scaling revisited
Marek M. Rams, Piotr Sierant, Omjyoti Dutta +2
We address the question whether the super-Heisenberg scaling for quantum estimation is realizable. We unify the results of two approaches. In the first one, the original system is…
Few interacting fermions in one-dimensional harmonic trap
Tomasz Sowiński, Tobias Grass, Omjyoti Dutta +1
We study spin-1/2 fermions, interacting via a two-body contact potential, in a one-dimensional harmonic trap. Applying exact diagonalization, we investigate their behavior at finit…
Coupling nanomechanical cantilevers to dipolar molecules
S. Singh, M. Bhattacharya, O. Dutta +1
We investigate the coupling of a nanomechanical oscillator in the quantum regime with molecular (electric) dipoles. We find theoretically that the cantilever can produce single-mod…
