Asymptotic and Catalytic Resource Orderings: Beyond Majorization
This talk is a progress report on ongoing research. I will explain what resource theories have to do with real algebraic geometry, and then present a preliminary result in real...

Speed of Gravity
Low energy effective field theories are usefully constrained by positivity bounds, i.e. positive signs for EFT interactions, derived from S-matrix analyticity. For non-gravitational theories S-matrix analyticity is consistent with the...

Structures of relative Gromov-Witten theory
Absolute Gromov-Witten theory is known to have many nice structural properties, such as quantum cohomology, WDVV equation, Givental's formalism, mirror theorem, CohFT etc.. In this talk, I will explain how...

New limits for large N matrix and tensor models
In this talk, I will describe the framework of large D matrix models, which provides new limits for matrix models where the sum over planar graphs simplifies when D is...

Strong Constraints on Superfluid Dark Matter from Milky Way Dynamics
Many well-known correlations between dark matter and baryons exist on galactic scales. These can essentially be encompassed by a simple scaling relation between observed and baryonic accelerations, historically known as...

Effective field theory near and far from equilibrium
In this talk I will discuss effective field theories for two classes of non-equilibrium systems, one far and one near equilibrium. The backbone of the approach is the Schwinger-Keldysh formalism...

Holographic Uhlmann Holonomy and the Entanglement Wedge Symplectic Form
Subregion duality is an idea in holography which states that every subregion of the boundary theory has a corresponding subregion in the bulk theory, called the 'entanglement wedge', to which...

On geometry and symmetries in gauge gravity: Cartan connection approach
Our earlier findings indicate the violation of the 'volume simplicity' constraint in the current Spinfoam models (EPRL-FK-KKL). This result, and related problems in LQG, promted to revisit the metric/vielbein degrees...

Tackling the challenges of galaxy-dark matter connection modeling and new insights into secondary (assembly) biases
Modeling galaxy-dark matter connection is essential in deriving unbiased cosmological constraints from galaxy clustering observations. We show that a more physically motivated galaxy-dark matter incorporating secondary (assembly) biases results in...
