Abstract: We study the gravitational effective action induced, at first order in the deformation parameter, by non-local $T\bar T$-like deformations of quantum field theories. Using a heat-kernel formulation, we extract the local geometric terms generated by stress-tensor two-point functions, and apply the construction to free fermions, massive Maxwell theory, and second-order Yang-Mills theory. While the resulting coefficients are generally model dependent, conformal field theories contain a universal sector fixed by the central charge $C_T$. After regularization and renormalization, this sector yields finite, scheme-independent contributions organized into a finite set of curvature invariants. We further analyze trace-trace deformations, for which the relevant contact terms are determined by the Weyl anomaly, and derive the corresponding finite gravitational action for a general class of minimal non-local kernels. These results provide a quantum effective-action realization of induced gravity in which universal conformal data determine calculable contributions to the emergent geometric response.

“The quality of the assessed criterion is weak, meaning it is not challenging relative to the international standard in the scientific domain. Many weaknesses or flaws can be identified and deserve absolutely to be addressed.”
Unfortunately, that perfectly describes the proposal I just spent 3½ hours reviewing.

The Newsom administration is suing five more California cities
— Calexico, Costa Mesa, Half Moon Bay, Ridgecrest and Turlock — for failing to complete state-mandated housing plans, known as the “housing element.”
Huntington Beach was the first city to face such a legal action, and it recently finalized its housing element plans following a court-order and massive fines.
The law, which has been in place since 1969, requires cities and counties every eight years to d…

Oops, that's a really nice screwup: bad NTP server taking down a large chunk of .au's phone network.
I guess NTP servers should probably have a 'before the release of this software' check in.

The massive surge of fossil fuel-powered data centers cropping up across the country
are emitting an enormous amount of pollution,
an indication that we’re headed in the wrong direction in the midst of a climate crisis.
The extent of the this polluting activity is confounding.
As climate action group Floodlight found in a recent investigation spotted by Wired, Texas has become the epicenter of the United States’ current obsession with constructing AI data centers.

Trump has ousted members of a bipartisan federal election commission that resisted his efforts to require would-be voters to document their U.S. citizenship before registering.
The White House on Friday confirmed the executive action against members of the Election Assistance Commission,
which distributes federal grants to states, oversees the testing of voting systems and maintains the national voter registration form.
It’s the latest instance of the Republican president t…

Senate Majority Leader John Thune’s political action committee dropped a massive
$53.9 million investment into the Texas Senate race, according to a Federal Election Commission filingsubmitted Monday.
The investment from Texas PAC, a committee associated with Thune’s Senate Leadership Fund, divided the media spending push:
Nearly $27 million will be used to support Republican nominee Ken Paxton, the Texas attorney general,
while $27 million is set to oppose Democratic …
