Universality of loop corrected soft theorems in 4d
In [1], logarithmic correction to subleading soft photon and soft graviton theorems have been derived in four spacetime dimensions from the ratio of IR-finite S-matrices. This has been achieved after factoring out IR-divergent components from the tradition ...
New York2023Covariant formulation of relativistic mechanics
Miguel Alexandre Ribeiro Correia
Accretion disks surrounding compact objects, and other environmental factors, deviate satellites from geodetic motion. Unfortunately, setting up the equations of motion for such relativistic trajectories is not as simple as in Newtonian mechanics. The prin ...
AMER PHYSICAL SOC2022General invariance and equilibrium conditions for lattice dynamics in 1D, 2D, and 3D materials
Nicola Marzari, Changpeng Lin, Samuel Poncé
The long-wavelength behavior of vibrational modes plays a central role in carrier transport, phonon-assisted optical properties, superconductivity, and thermomechanical and thermoelectric properties of materials. Here, we present general invariance and equ ...
NATURE PORTFOLIO2022Physics-enhanced machine learning with symmetry-adapted and long-range representations
Theoretical and computational approaches to the study of materials and molecules have, over the last few decades, progressed at an exponential rate. Yet, the possibility of producing numerical predictions that are on par with experimental measurements is t ...
