The Unruh Effect predicts an accelerated observer measures the vacuum to instead be a thermal bath of particles. It’s never been observed. Today Netta Engelhardt, Lindley Winslow, and I have a proposal to measure it: arxiv.org/abs/2607.17744. @bhi-harvard.bsky.social #physics

Measuring the Acceleration-Dependent Temperature of the Minkowski Vacuum

Relativistic quantum field theory is the structure on which the Standard Model and beyond-Standard Model physics are built. One of its most striking predictions is the Unruh effect: an accelerating ob...

Whatever direction you look into the night sky, at very large scales, the universe looks similar. What might explain this “isotropy”? A new take on this old question: arxiv.org/abs/2605.11085. Thanks to my coauthors in this new line of inquiry, Bruno Alexandre, Stephon Alexander & David Spergel.

A Quantum Gravitational Mechanism for Isotropization of de Sitter Cosmologies

Today, the observable cosmos exhibits a remarkable degree of isotropy and plausibly began in a nearly isotropic initial state. The properties of the Lorentzian Chern-Simons-Kodama (CSK) functional can...

We’re bringing together many of the people who've laid the foundations of our modern understanding of thermal physics in quantum field theory for conference in Sao Paolo this summer, August 3 - 7, with ICTP SAIFR and Instituto Principia. I hope you can join!!!

Merry Christmas! I’m grateful to Gautam Satishchandran, my coauthor on this new article. In it we show that black holes decohere their environments as if they're full of optimal observers!

As promised... No, classical spacetime can’t produce entanglement. I can create entanglement by turning a knob on a laser, but the knob isn't mediating entanglement. Is the knob "producing" the entanglement? This week's Nature paper is causing confusion! superposer.substack.com/p/no-classic... 🧪⚛️

If you're an academic talking to non-academics---or hell, even academics outside your field---you have a responsibility to distinguish between "this is the scholarly consensus" and "this is an active debate which I'm on one side of."

An eavesdropper hiding inside of a black hole could still obtain information about quantum objects on its outside, a finding that reveals how effectively black holes destroy the quantum states near their event horizons.

If neutrinos are Majorana particles—that is, if they are their own antiparticles—a process called neutrinoless double-beta decay should occur. A new and sensitive search has not found it.

Search Continues for Neutrinoless Decay

Observations of molybdenum nuclei have revealed no signs of a speculative nuclear decay called neutrinoless double-beta decay, setting a strong constraint on this process.
