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 …
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…
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…
Measurement as Sheafification: Context, Logic, and Truth after Quantum Mechanics
Partha Ghose
Quantum measurement is commonly posed as a dynamical tension between linear Schrödinger evolution and an ad hoc collapse rule. I argue that the deeper conflict is logical: quantum…
A Contextual Seven-Valued Logic (\emph{Saptabhangīnaya}) for Quantum Systems
Partha Ghose
The quantum measurement problem is often presented as a conflict between unitary evolution and non-unitary collapse. Drawing on Wittgenstein's later philosophy of language and Bohr…
Context and Complementarity: Formalizing Bohr's Vision through Many-Valued Contextual Logic
Partha Ghose, Sudip Patra
Quantum mechanics challenges classical intuitions of space, time, and causality via the superposition principle, which allows systems to exist in multiple states simultaneously. Ni…
Intersystem Non-separability and CHSH-Bell Violations in Classical Optics
Partha Ghose
A method is proposed to produce a classical optical state that is `intersystem nonseparable' and a close analog of the Bell state. A derivation of the CHSH-Bell inequality is…
