Physics beyond the standard model from Higgs Parity
The discovery of the Higgs boson has revealed that the quartic Higgs self-coupling becomes small at very high energy scales. Guided by this observation, I introduce Higgs Parity, which is...

Holographic cosmology: status report
I will give an overview of holographic cosmology and discuss recent results and work in progress. In holographic cosmology time evolution is mapped to inverse RG flow of the dual...

Cayley path and quantum supremacy: Average case #P-Hardness of random circuit sampling
Given the large push by academia and industry (e.g., IBM and Google), quantum computers with hundred(s) of qubits are at the brink of existence with the promise of outperforming any...

Bulk observables in JT gravity
Using a definition of bulk diff-invariant observables, we go into the bulk of 2d Jackiw-Teitelboim gravity. By mapping the computation to a Schwarzian path integral, we study exact bulk correlation...

The Python's Lunch: geometric obstructions to decoding Hawking radiation
Harlow and Hayden [ arXiv:1301.4504 ] argued that distilling information out of Hawking radiation is computationally hard despite the fact that the quantum state of the black hole and its...

Casimir and free energy for free fields and holographic theories in 2+1 on curved spaces
We investigate putting 2+1 free and holographic theories on a product of time with a curved compact 2-d space. We then vary the geometry of the space, keeping the area...

Quantum homeopathy works: Efficient unitary designs with a system-size independent number of non-Clifford gates
Many quantum information protocols require the implementation of random unitaries. Because it takes exponential resources to produce Haar-random unitaries drawn from the full n-qubit group, one often resorts to t-designs...

Nonlinear dynamical tides in white dwarf binaries
Compact white dwarf (WD) binaries are important sources for space-based gravitational-wave (GW) observatories, and an increasing number of them are being identified by surveys like ELM and ZTF. We study...
