Contextuality, Locality, and the Interpretation of Bell Violations
Partha Ghose
The ontological significance of violations of Bell inequalities is reexamined. Bell's theorem admits several mathematically equivalent formulations that support different interpret…
Leggett--Garg Tests in Neural Dynamics: Probing Non-Diffusive Stochastic Structure in Single Neurons
Partha Ghose
We propose an experimental programme to test Leggett--Garg-type temporal correlations in single-neuron dynamics. The goal is to distinguish between diffusive (Wiener/cable-equation…
Nelson's Stochastic Mechanics: Measurement, Nonlocality, and the Classical Limit
Partha Ghose
Nelson's stochastic mechanics may be understood as a stochastic underpinning, or reconstruction, of nonrelativistic quantum mechanics, once the diffusion scale is fixed by …
Bell-like States in Classical Optics: A Process-Theoretic and Sheaf-Theoretic (Categorical) Clarification
Partha Ghose
Classical polarization optics is naturally described by a two-dimensional complex Hilbert space (Jones vectors), so the tensor-product kinematics underlying bipartite nonseparabili…
Indefinite Causal Order from Failure-to-Glue: Contextual Semantics and Parametric Time
Partha Ghose
Indefinite causal order (ICO) has been studied via higher-order quantum processes (e.g.\ the quantum switch), process matrices, and quantum-gravity proposals involving superposed c…
Einstein's Worries and Actual Physics: Beyond Pilot Waves
Partha Ghose
Tim Maudlin has argued that the standard formulation of quantum mechanics fails to provide a clear ontology and dynamics and that the de Broglie--Bohm pilot-wave theory offers a be…
