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…
