Representation theory of the Clifford group: Schur-Weyl Duality for the Clifford Group, Property Testing, and de Finetti Representations
Schur-Weyl duality is a ubiquitous tool in quantum information. At its heart is the statement that the space of operators that commute with the tensor powers of all unitaries is...

MIP* = RE
MIP* denotes the class of problems that admit interactive proofs with quantum entangled provers. It has been an outstanding question to characterize the complexity of this class. Most notably, there...

Classical algorithms, correlation decay, and complex zeros of partition functions of quantum many-body systems
Basic statistical properties of quantum many-body systems in thermal equilibrium can be obtained from their partition function. In this talk, I will present a quasi-polynomial time classical algorithm that estimates...

LQG in diagonal gauge: A modern approach
The full theory of LQG presents enormous challenge to create physical computable models. In this talk we will present the new modern version of Quantum Reduced Loop Gravity. We will...

The small mass-ratio expansion of the relativistic two body problem
To predict the gravitational waves emitted by a black hole binary, one needs to understand the dynamics of the binary in general relativity. No closed form solutions of this problem...

Asymptotics of the eprl model on arbitrary vertices
We introduce a new technique to study the critical point equations of the eprl model. We show that it correctly reproduces the 4-simplex asymptotics, and how to apply it to...

LHC opportunities in long-live signatures from the hidden sectors
The LHC bear great potential in seeking for hidden sector particles, such as a high-quality QCD axion, glueballs, and heavy neutrinos. In this talk, I will present my recent studies...

Spring-loading electrons and other shenanigans of superoscillatory wave functions
A superoscillatory function is a bandlimited function that, on some interval, oscillates faster than the highest frequency component shown in the function's Fourier transform. Superoscillations can be arbitrarily fast and...

Exact bosonization in all dimensions and the duality between supercohomology fermionic SPT and higher-group bosonic SPT phases
The first part of this talk will introduce generalized Jordan–Wigner transformation on arbitrary triangulation of any simply connected manifold in 2d, 3d and general dimensions. This gives a duality between...

Simulating Galaxy Formation: Illustris, IllustrisTNG and beyond
Cosmological simulations of galaxy formation have evolved significantly over the last years. In my talk I will describe recent efforts to model the large-scale distribution of galaxies with cosmological hydrodynamics...
