Exactly Solvable Floquet Dynamics for Conformal Field Theories in Dimensions Greater than Two

The paper investigates the dynamics of conformal field theories (CFTs) in 3+1 dimensions under periodic driving protocols involving different deformations of the CFT Hamiltonian. By employing conformal transformations and a quaternion formalism, the authors calculate quantities like fidelity, unequal-time correlators, and energy density, demonstrating the existence of heating and non-heating phases depending on the drive parameters. For protocols with a single SU(1,1) subalgebra of the conformal group involved, the Floquet Hamiltonian is derived, enabling the study of dynamical phase transitions.

The anomalous magnetic moment of the muon in the Standard Model

The Standard Model calculation of the muon anomalous magnetic moment is a complex undertaking, involving contributions from QED, electroweak interactions, and hadronic effects. The current theoretical prediction differs from the experimental measurement by 3.7 standard deviations, suggesting the potential presence of new physics. However, the uncertainties associated with the hadronic contributions, particularly HVP and HLbL, are still significant and limit the ability to draw definitive conclusions.

Magnetic control of tokamak plasmas through deep reinforcement learning

This paper demonstrates successful real-time control of plasma shape and position in a tokamak using deep reinforcement learning. The controller, trained in simulation and deployed directly on the TCV tokamak, successfully stabilized a variety of plasma configurations, including advanced shapes like snowflakes and even two independent plasmas (droplets). This approach simplifies control design compared to conventional methods and enables more flexible exploration of new plasma configurations.

Replica wormholes and the entropy of Hawking radiation

This paper demonstrates how non-perturbative effects from "replica wormholes" can resolve the late-time entropy discrepancy for Hawking radiation, leading to a unitary Page curve. By including these new saddle points in the gravitational path integral, the island rule for computing entropy emerges naturally, suggesting a new way to understand how information escapes black holes.

Entanglement wedge reconstruction and the information paradox

This paper uses entanglement wedge reconstruction in AdS/CFT to show how information escapes from black holes after the Page time. It derives both the Page curve for the entanglement entropy of an evaporating black hole and the Hayden-Preskill criterion for decoding information thrown into the black hole.

Electrochemically induced nuclear fusion of deuterium

The authors claim to have observed excess heat generation in palladium cathodes during electrolysis of heavy water, suggesting nuclear fusion. However, the measured neutron and tritium levels are far too low to explain the observed heat, and the study suffers from methodological limitations and safety concerns.
