For Pauli stabilizer codes—such as surface codes and color codes—transversal logical gates are strongly constrained by the Bravyi–König bound. In particular, implementing a non-Clifford gate transversally (as required for universality) demands three...

Among many things, dark matter could be made of new fundamental or composite particles, which may feebly interact with nuclei or electrons (“baryons”), as well as with themselves. Cosmological observables are a promising avenue to test such...

It is believed that topologically ordered gapped local Hamiltonians in 2+1d consisting of commuting terms may not realize a chiral anyon theory. There is even a formula that expresses the chiral central charge of the edge theory as an integral of...

Binary stars in the central parsecs of galaxies are involved in the production of several modern astronomical phenomena, including hypervelocity stars, repeating partial tidal disruption events, and dust-enshrouded objects around Sgr A*. I present...

We explain how to tropicalize scalar quantum field theory and show that tropicalized massive scalar quantum field theory is exactly solvable. This exact solution manifests as a non-linear recursion equation fulfilled by the expansion coefficients of...

Conformal field theories in 3D are central to condensed-matter and high-energy physics. Among them, critical gauge theories, especially Chern-Simons-matter theories, stand out: They describe transitions where one or both phases are topologically...

Astrophysical black holes are surrounded by accretion disks, jets, magnetospheres, and coronae consisting of magnetized relativistic plasma. They produce observable multi wavelength and multi messenger signals from near the event horizon and it is...

Entanglement Bootstrap is a research program to understand and extract the universal data of quantum many body states from local entanglement information.  Since this universal data is usually encoded in a quantum field theory, the program can teach...

This talk has two parts. In the first, I will discuss a well-known Lorentzian axiomatic framework in which quantum gravity theorems can be rigorously established, with the quantum extremal surface prescription as a central highlight. I will describe...
