Really feeling this right now, but it’s a LOT more than just 2.

Quenching of excitons at grain boundaries in C60 thin films
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and therefore grain boundaries, impacts exciton dynamics in thin films of C60/Au(111) using time and angle-resolved photoemission spectroscopy (TR-ARPES). We find that films with multiple rotational domains exhibit shorter exciton lifetimes and evidence of exciton-exciton annihilation, even when one domain predominates. Scanni…

Content warning: Medical stuff / MRI selfie

On the 10th of December 2024 at about 4pm in the afternoon I had a sudden shivering attack. The room wasn't cold, but I was, so I took to bed and shivered on the electric blanket until I napped for a few hours.
Woke up groggy, and never got better. Feeling light headed and occasionally dizzy and half stoned all the time. Can't handle booze or dope at all any more. Doing the job feels like trying to program drunk, concentration shot and short term memory failing.
Various doctors have ordered batteries of tests and put me on drugs to reduce my blood pressure but nothing that's really helped.
They did an MRI last week. Apparently everything looks normal which is good I guess, but still leaves symptoms unexplained.
There are worse fates than feeling half drunk all the time I suppose.
Given no visible brain damage, about the best suggestion anyone has is to stay off booze and drugs (which is easy, since I can't handle them any more) and get back to meditation. If it's damage so small the MRI can't pick it up it'll get better slowly probably. 🤷
Anyway, they gave me the MRI data upon request, so I spent most of yesterday importing it into Blender and making some visualization.
Ladies and gentlemen, I present: My apparently completely normal brain in an MRI selfie.

Stochastic dark matter: Covariant Brownian motion from Planckian discreteness
Quantum gravity has long remained elusive from an observational standpoint. Developing effective cosmological models motivated by the fundamental aspects of quantum gravity is crucial for bridging theory with observations. One key aspect is the granularity of spacetime, which suggests that free particles would deviate from classical geodesics by following a covariant Brownian motion. This notion is further supported by swerves models in causal set theory, a discrete approach to quantum gravity.…

A Casimir-like probe for 4D Einstein-Gauss-Bonnet gravity
Virtual transitions in a Casimir-like configuration are utilized to probe quantum aspects of four-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity. This study employs a quantum optics-based approach, wherein an Unruh-DeWitt detector (modeled as a two-level atom) follows a radial timelike geodesic, falling freely into an uncharged, nonrotating black hole described by 4D EGB gravity, becoming thermalized in the usual Unruh manner. The black hole, asymptotically Minkowskian, is enclosed by a Cas…
