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…
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…
