Non-Fermi liquid behavior of large N_B quantum critical metals
A. Liam Fitzpatrick, Shamit Kachru, Jared Kaplan +1
The problem of continuous quantum phase transitions in metals involves critical bosons coupled to a Fermi surface. We solve the theory in the limit of a large number, N_B, of boson…
Model-independent WIMP Scattering Responses and Event Rates: A Mathematica Package for Experimental Analysis
Nikhil Anand, A. Liam Fitzpatrick, W. C. Haxton
The community's reliance on simplified descriptions of WIMP-nucleus interactions reflects the absence of analysis tools that integrate general theories of dark matter with standard…
Non-Fermi liquid fixed point in a Wilsonian theory of quantum critical metals
A. Liam Fitzpatrick, Shamit Kachru, Jared Kaplan +1
We study the problem of disorder-free metals near a continuous quantum critical point. We depart from the standard paradigm of Hertz and Millis, and treat both fermions and bosons…
Conformal Blocks in the Large D Limit
A. Liam Fitzpatrick, Jared Kaplan, David Poland
We derive conformal blocks in an inverse spacetime dimension expansion. In this large D limit, the blocks are naturally written in terms of a new combination of conformal cross-rat…
Decoupling of High Dimension Operators from the Low Energy Sector in Holographic Models
A. Liam Fitzpatrick, Jared Kaplan, Emanuel Katz +1
We study the decoupling of high dimension operators from the the description of the low-energy spectrum in theories where conformal symmetry is broken by a single scale, which we r…
The Analytic Bootstrap and AdS Superhorizon Locality
A. Liam Fitzpatrick, Jared Kaplan, David Poland +1
We take an analytic approach to the CFT bootstrap, studying the 4-pt correlators of d > 2 dimensional CFTs in an Eikonal-type limit, where the conformal cross ratios satisfy |u| <<…
