LGRT 1033
This workshop will highlight recent progress in understanding the landscape of quantum gravities, as well as defining the important open questions and developing connections with different areas of particle theory. The themes of the program will mimic the various approaches used to tackle this problem from top-down to bottom-up constructions as well as relating constraints from cosmology, holography and generalized symmetry structures.

LGRT 419B
This workshop will focus on our understanding of the equation of state of dense nuclear matter by exploring the connections between terrestrial measurements of neutron skins of nuclei and astrophysical measurements of the properties of neutron stars.
The workshop is timely because of the newly completed running of the PREX-II and CREX experiments at Jefferson Lab, new data from NICER and the upcoming fourth observing run of LIGO/Virgo/KAGRA. It is now time to bring these fields together, formulate a common language and coordinate future directions in both theory and experiment, with the shared goal of understanding neutron matter, from microscopic to the macroscopic scales.

Neutrino-less double beta decay is the most sensitive probe of lepton number violation and a powerful tool to study the origin of neutrino masses. Currently, experimental efforts are gearing up for the so-called "tonne-phase" searches, with sensitivity reach of T_1/2 ~ 10^28 years. In the US, this phase is under the stewardship of the DoE Office of Nuclear Physics.
This workshop aims at defining experimental paths for studying neutrinoless double beta decay beyond the "tonne-scale" and at providing theoretical guidance. From the theoretical point of view, it is important to frame both discoveries or lack thereof made by the tonne-scale experiments. The experimental challenges include reaching ~100x higher sensitivity (T_1/2 ~ 10^30 years) and extracting more information from double-beta decay events. The workshop is organized in the broader context of the Snowmass 2021 process. It follows the collection of numerous DBD-flavored LOIs in Summer 2020, and is meant to define the main thrusts along which contributed papers will be prepared in 2021 and to identify both goals and the community to carry this program in the coming 1-2 decades.

Realizing the full potential of experimental studies of nuclear matter requires a comprehensive understanding of the dynamics of its microscopic constituents, within the theory of quantum chromodynamics (QCD). Lattice QCD calculations have made significant contributions to our understanding of the strong interaction, but little is known from ab initio calculations about the dynamical properties of quarks and gluons. A central challenge for such calculations is the need to solve ill-posed inverse problems. This workshop will bring together practitioners in the field of lattice QCD and other communities working with inverse problems to address recent progress and remaining challenges in the extraction of dynamical properties from both numerical calculations and from experiment.
