Bell Inequalities and Maximally Realistic Causal Quantum Mechanics
S. M. Roy
The De Broglie-Bohm (DeBB)\cite{DeBB} Causal Quantum Mechanics played a crucial role in Bell's discovery \cite{Bell1964} that quantum mechanics violates EPR local reality \cite{EPR…
Separability inequalities on N-qudit correlations exponentially stronger than local reality inequalities
S. M. Roy
I derive separability inequalities for Bell correlations of observables in arbitrary pure or mixed Qudit states in -dimensional state space. I find states (a continuum of…
Generic Contractive States and Quantum Monitoring of Free Masses and Oscillators
Priyanshi Bhasin, Ujan Chakraborty, S . M. Roy
Monitoring photon quadratures and free masses are useful tools to detect small disturbances such as gravitational waves.Here we report a large class of states for photon quadrature…
Arbitrarily large violations of non-contextuality in single mode photon states with positive Wigner function
S. M. Roy
Banaszek, Wódkiewicz and others (\cite{Banaszek},\cite{Chen},\cite{Chen-Zhang}) made the surprising discovery that Einstein-Bell locality inequalities can be violated by the two mo…
Rigorous Quantum Limits on Monitoring Free Masses and Harmonic Oscillators
S. M. Roy
There are heuristic arguments proposing that the accuracy of monitoring position of a free mass is limited by the standard quantum limit (SQL):$σ^2 (X(t)) \geq σ^2 (X(0)) +(t^2…
A Lower Bound on Inelasticity in Pion-Pion Scattering
André Martin, S. M. Roy
Assuming that the pion-pion scattering amplitude and its absorptive part are analytic inside an ellipse in - plane with foci , and right extremity , ($ε…
