Improving cosmological reach of a gravitational wave observatory using Deep Loop Shaping

Posted by klaurent Caltech

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: , , , , | Summary: Improved low-frequency sensitivity of gravitational wave observatories would unlock study of intermediate-mass black hole mergers, binary black hole eccentricity, and provide early warnings for multi-messenger observations of binary neutron star mergers. Today’s mirror stabilization control injects harmful noise, constituting a […]

Accurate ground states of $SU(2)$ lattice gauge theory in 2+1D and 3+1D

Posted by klaurent Delft

Kavli Affiliate: Eliska Greplova | First 5 Authors: Thomas Spriggs, Thomas Spriggs, , , | Summary: We present a neural network wavefunction framework for solving non-Abelian lattice gauge theories in a continuous group representation. Using a combination of $SU(2)$ equivariant neural networks alongside an $SU(2)$ invariant, physics-inspired ansatz, we learn a parameterization of the ground […]
