Abstract: The ability to address sub-picosecond events of weak optical signals is essential for progress in quantum science, nonlinear optics, and ultrafast spectroscopy. While up-conversion and optical Kerr gating (OKG) offer femtosecond resolution, they are generally limited to ensemble measurements, making ultrafast detection in nano-optics challenging. OKG, with its broadband response and high throughput without phase-matching, is especially promising when used at high repetition rates under focused illumination.
Here, we demonstrate an ultrafast detection scheme using the third-order nonlinearity of graphene and thin graphite films, operating at 1 GHz with sub-nanojoule pulses and achieving 141 fs temporal resolution. Their exceptionally large nonlinear refractive index, orders of magnitude higher than conventional Kerr media, enhances detection efficiency at smaller thicknesses, enables sub-picosecond response, and supports broadband operation. Their atomic-scale thickness minimizes dispersion and simplifies integration with microscopy platforms, optical fibers, and nanophotonic circuits, making them a compact, practical material platform for nano-optical and on-chip ultrafast Kerr gating.

Lately, I’ve been feeling burned out by how much people in my life assume things about me and my beliefs, so let's talk about it.
I spend some parts (not all) of my evenings online, usually from around 20:00 to 22:00 or sometimes even until midnight (00:00), not because I am consumed by politics but because I like to learn and reflect on how society could be better. I enjoy exploring ideas about justice, solidarity, and human rights in a way that feels meaningful to me. For me, spe…

1/ Pretty epic falling out with C yesterday. It started first thing in the morning when I discovered she hadn’t phoned the doctors to make an appointment. She’s bed bound with abdominal pain meaning that I’m having to care for her and baby full time. I’m happy to do that but I do expect C to play her part by seeking medical help. She did then contact the surgery, but doing it late meant she was unlikely to get a same day appointment.

A broad retreat is underway in the nonprofit world.
After Donald Trump ordered his administration to root out “illegal” diversity, equity and inclusion efforts earlier this year,
opening the door to investigations and funding cuts for offenders,
more than 1,000 charities rewrote their mission statements in forms they filed this year with the Internal Revenue Service,
removing or minimizing language tied to race, inequity and historically disadvantaged communities.<…

Deleting DEI
As the Trump administration ordered agencies to eradicate “illegal” diversity, equity and inclusion efforts, we identified more than 1,000 nonprofits that removed such language from the mission statements in their tax filings.

‘Green’ energy transition leaves a dirty trail in the Philippines’ nickel belt
MINDANAO, Philippines — Communities living near mining operations in the southern Philippines’ Caraga region are feeling the toll of the global energy transition, with nickel mining driving deforestation and pollution, according to a recent report. Climate Rights International (CRI), the U.S.-based NGO behind the report, highlighted harms to the environment, local livelihoods and public health […]

Sounds easy, looks nice: Crossmodal transfer of auditory processing fluency to visual object preference - Attention, Perception, & Psychophysics
Fluent (i.e., rapid and efficient) processing of perceptual objects is vital for humans to successfully navigate their environments. The experience of fluent processing per se tends to trigger positive affect; however, this affect is often misattributed by perceivers to the objects themselves, meaning that easy-to-perceive objects are judged more positively. These fluency-based preference effects have been robustly demonstrated unimodally, and specifically in situations in which fluency and pre…

The president of the United States is invading multiple US cities and liberal strongholds, in troop deployments that are now the primary component of his vast, lawless, smash-and-grab efforts to shred the nation’s constitutional and democratic order, all in the service of his personality cult.
And his enthusiasm for doing so is partially, and meaningfully, fueled by how mad he gets while binge-watching hours and hours of TV, current and former Trump advisers tell Zeteo.

Trump’s Addiction to Watching Fox Is Killing American Democracy
Our country is falling apart because one old man, Trump advisers and former administration officials say, won’t stop ‘yelling’ at his TV.
