Abstract: We present an innovative cluster-based method employing linear combinations of diverse cluster mean-field states and apply it to describe the ground state of strongly correlated spin systems. In cluster mean-field theory, the ground state wave… read more here.

Abstract: Electromagnetic field states in optical cavities can show classical-nonclassical transition due to interaction with matter in the cavity. We analyze non-classicality in cavity-field state using negativity in its phase-space (quasi) distribution. We show that induced… read more here.

Abstract: We analyze the interactions of particle detectors with coherent states of a free scalar field. We find that the eigenvalues of the post-interaction density matrices of i) a single detector, ii) two detectors, and iii)… read more here.
