Although it is known that AdS/CFT as a quantum erasure
correction code is only approximate, there is still much to learn
about the precise bulk physical consequences of deviating from
exact erasure correction codes. In this talk, I will take...
Computing the entropy of probability distributions and quantum
states is a fundamental task in information processing. In this
talk I'll discuss recent work with Matty Hoban (arXiv:2002.12814)
in which we show that estimating the entropy of quantum...
We introduce a theoretical framework to study experimental
physics using quantum complexity theory. This allows us to address:
what is the computational complexity of an experiment? For several
'model' experiments, we prove that there is an...
We take the tensor network describing explicit p-adic CFT
partition functions proposed in 1902.01411, and consider boundary
conditions of the network describing a deformed Bruhat-Tits (BT)
tree geometry. We demonstrate that this geometry satisfies...
I shall present joint work with Maxim Kontsevich
(arXiv:2105.10161) describing an interesting domain of complex
metrics on a smooth manifold. It is a complexification of the space
of ordinary Riemannian metrics, and has the Lorentzian metrics
(but...
What governs whether large-scale planetary habitability is
sustained through time? Lakes, valley networks, groundwaters,
hydrothermal systems, and chemically open-system weathering once
existed on Mars. The suite of aqueous environments preserved
in...
Abstract 1: In recent years, weak lensing of the cosmic
microwave background (CMB) has emerged as a powerful tool to probe
fundamental physics. The prime target of CMB lensing surveys is the
lensing potential, which is reconstructed from observed...
