991. xCPS: A Computational Toolkit for Covariant Phase Space Methods

Juan Margalef (Université de Montréal)

24/06/2026, 10:15

Theoretical Physics / Physique théorique (DTP-DPT)

Invited Speaker / Conférencier(ère) invité(e)

The covariant phase space (CPS) formalism provides a geometric framework to derive equations of motion and endow the space of solutions with a symplectic structure. This variational approach additionally provides Noether charges and plays a central role in modern gravitational physics and gauge theories. Despite its conceptual elegance, explicit computations in physically relevant models...

499. Bosonization of Noise Effects on Nonlocal Open Quantum Dynamics

Oral (Non-Student) / Orale (non-étudiant(e))

Quantum systems that interact non-locally with an environment are paradigms for exploring collective phenomena. They naturally emerge in various physical contexts involving long-range,vmany-body interactions. We consider a general class of such open systems characterized by a coupling to the environment which is inversely proportional to the square root of the environmentvsize. We demonstrate...

869. Quantum-like features in classical mechanics

Mustafa Amin (University of Lethbridge)

Theoretical Physics / Physique théorique (DTP-DPT)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Hilbert space, superposition, uncertainty relations, and Wigner negativity, are terms usually associated with quantum phenomena and formalism. We show that all of these have analogues in classical mechanics, and attempt to explain their (in hindsight, unsurprising) meaning in a classical context. This is in an effort to characterize and identify the root of the differences between classical...

498. Bridging the Gap between Classical and Quantum Mechanics through General Relativity.

Prof. Réjean Plamondon

24/06/2026, 11:15

Theoretical Physics / Physique théorique (DTP-DPT)

Oral (Non-Student) / Orale (non-étudiant(e))

This paper proposes a conceptual framework to bridge the gap between classical and quantum mechanics using an emergent paradigm that positions general relativity into a probabilistic context. Starting from an analogy between Einstein equations and Bayes law, the linear case of a weak field static symmetric massive object is analyzed to point out how Einstein’s equation could incorporate a...

705. An Isomorphism between Quantum Nonlocality and the Relativity of Colocality

Prof. Jonathan Sharp (University of Alberta)

24/06/2026, 11:30

Theoretical Physics / Physique théorique (DTP-DPT)

Oral (Non-Student) / Orale (non-étudiant(e))

Understanding Bell nonlocality (EPR) in the context of relativistic spacetime is a longstanding problem in the foundations of physics. Here, we show that an observer-centric reinterpretation of the ontology of classical special relativistic spacetime (for an ensemble of observers) exhibits sufficiently close parallels to the phenomena of quantum non-locality that we can claim that the two sets...

664. Time-Symmetric Nonlinear Dynamics and the Emergence of Objective Wavefunction Collapse in Strongly Correlated t-U-V-J Manifolds

Prof. Godfrey Ejiroghene Akpojotor (Delta State University, Abraka, Nigeria)

24/06/2026, 11:45

Theoretical Physics / Physique théorique (DTP-DPT)

Oral (Non-Student) / Orale (non-étudiant(e))

In this study, we propose a unified theoretical framework for objective wavefunction collapse by situating non-linear quantum dynamics within a time-symmetric manifold. Utilizing the Highly Simplified Correlated Variational Approach (HSCVA), we map the t-U-V-J Hamiltonian of strongly correlated electronic systems onto a non-linear temporal landscape. We introduce the Extended Dirac Principle...
