Building and (hints of) seeing gravitational statistical mechanics
Seth Major - Hamilton College
A statistical mechanics of geometry based on the quasi-local energy of constantly accelerating observers outside black holes is proposed. By assuming particle statistics for the geometric quanta, the geometry condenses in the large area limit, providing a quantum gravity cutoff for the entropy of…
Gravitational collapse, shock waves and white holes
Viqar Husain - University of New Brunswick
I will describe an effective quantum gravity model for dust collapse that predicts a shock wave as the end point of a black hole, and smooth metrics for black hole to white hole transitions.
To Lee, with best wishes
Abhay Ashtekar - Pennsylvania State University
I will make a few remarks of both scientific and personal nature to celebrate Lee's contributions to our field.
Cosmology, Quantum Gravity and a Constant
Stephon Alexander - Brown University
Cosmological data is consistent with a positive cosmological constant. In this talk I discuss an approach pioneered by Smolin that uses a non-perturbative exact quantization of gavity with a cosmological constant in the Ashtekar formalism. I discuss follow up work by the Author and his collaborators…
One of us would be superfluous
Carlo Rovelli - Aix-Marseille University
I will tell stories. About Lee's physics. About his insights that have shaped many of the ideas that we take for granted today. From the birth of Loop Quantum Gravity to the discreteness of physical space.
Probing Quantum Features of Gravity in Tabletop Regime and Reassessing the I.I.D. Assumption in Quantum Probability Assignments
Linqing Chen - Austrian Academy of Sciences
Recent advancements in tabletop experiments may offer the first empirical proof that gravity is not classical. In the first part of my talk, I will present two effects that overcome the current limitations of Newton potential phenomenology, involving generic quantum sources of gravity. These effects…
von Neumann algebraic quantum information theory and entanglement in infinite quantum systems
Lauritz van Luijk - Leibniz University Hannover
In quantum systems with infinitely many degrees of freedom, states can be infinitely entangled across a pair of subsystems. But are there different forms of infinite entanglement? In the first part of my talk, I will present a von Neumann algebraic framework for studying information-theoretic…
Flatness and spikes in Ponzano-Regge
The original spinfoam amplitude, Ponzano-Regge, has two properties in seeming contradiction: (1.) It can be written as an integral of a product of Dirac delta functions imposing that holonomies be exactly flat, and (2.) In its original sum-over-spins form, its leading order large spin asymptotics…
Theoretical physics at ELI ERIC
Sergey Bulanov
As part of a visit to Perimeter of a delegation from the ELI Beamlines laser facility in the Czech Republic, Dr. Bulanov will speak about potential topics for collaboration between Perimeter Institute and ELI theorists on topics related to high energy laser physics. To highlight the interplay…
