Tomographic discord for a system of two coupled nanoelectric circuits
, 2015 We consider quantum correlations and quantum discord phenomena for two-qubit states with $X$-type density matrices in the tomographic framework of quantum mechanics.

Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization
Annalen der Physik, EarlyView.A notable asymmetry is shown to characterize the bistable switching between macroscopic metastable states of light in the strong‐coupling limit of radiation–matter interaction. Transitions from the vacuum to a highly excited state correlate with a highly bunched sequence of emitted photons, while a downward switch to the vacuum involves a coherent ...

Global Quantum Discord in Multipartite Systems
, 2011 We propose a global measure for quantum correlations in multipartite systems, which is obtained by suitably recasting the quantum discord in terms of relative entropy and local von Neumann measurements.

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity
Annalen der Physik, EarlyView.This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

Quantum Correlations Between Identical and Unidentical Atoms in a Dissipative Environment
, 2011 We have studied the dynamics of quantum correlations such as entanglement, Bell-nonlocality and quantum discord between identical as well as unidentical atoms interacting with a single-mode cavity field and subject to cavity decay.

Quantum Correlations in non-Markovian Environments
, 2010 We have studied the analytical Markovian and non-Markovian dynamics of quantum correlations, such as entanglement, quantum discord and Bell nonlocalities for three noisy qubits.

Assisted state discrimination without entanglement
, 2012 It is shown that the dissonance, a quantum correlation which is equal to quantum discord for separable state, is required for assisted optimal state discrimination.

Non-Markovian Dynamics of Quantum Discord
, 2010 We evaluate the quantum discord dynamics of two qubits in independent and common non-Markovian environments. We compare the dynamics of entanglement with that of quantum discord.

ChemPhysChem, EarlyView.Octahedral distortion parameters in two‐dimensional hybrid organic‐inorganic perovskites, as calculated by Python code, are correlated with electronic and optical properties. Structure, Dresselhaus spin splitting, and anisotropic optical transitions of synthesized chiral and achiral lead bromide perovskites are computationally analyzed. A computational
