The Gauge Theory Bootstrap: Predicting pion dynamics from QCD
Yifei He, Martin Kruczenski
The Gauge Theory Bootstrap [arXiv:2309.12402, arXiv:2403.10772] computes the strongly coupled pion dynamics by considering the most general scattering matrix, form factors and spec…
Gauge Theory Bootstrap: Pion amplitudes and low energy parameters
Yifei He, Martin Kruczenski
Following the Gauge Theory Bootstrap method proposed in our previous work [arXiv:2309.12402], we compute pion scattering phase shifts for all partial waves with angular momentum $\…
Bootstrapping gauge theories
Yifei He, Martin Kruczenski
We consider asymptotically free gauge theories with gauge group and quarks with mass that undergo chiral symmetry breaking and confinement.…
From conformal correlators to analytic S-matrices: CFT/QFT
Lucía Córdova, Yifei He, Miguel F. Paulos
We study families of one-dimensional CFTs relevant for describing gapped QFTs in AdS. Using the Polyakov bootstrap as our main tool, we explain how S-matrices emerge from the f…
A note on the identity module in CFTs
Yifei He, Hubert Saleur
It has long been understood that non-trivial Conformal Field Theories (CFTs) with vanishing central charge () are logarithmic. So far however, the structure of the identity mo…
S-matrix bootstrap in 3+1 dimensions: regularization and dual convex problem
Yifei He, Martin Kruczenski
The S-matrix bootstrap maps out the space of S-matrices allowed by analyticity, crossing, unitarity, and other constraints. For the scattering matrix $S_{2\rightar…
The action of the Virasoro algebra in the two-dimensional Potts and loop models at generic
Linnea Grans-Samuelsson, Lawrence Liu, Yifei He +2
The spectrum of conformal weights for the CFT describing the two-dimensional critical -state Potts model (or its close cousin, the dense loop model) has been known for more than…
Geometrical four-point functions in the two-dimensional critical -state Potts model: The interchiral conformal bootstrap
Yifei He, Jesper Lykke Jacobsen, Hubert Saleur
Based on the spectrum identified in our earlier work [arXiv:1809.02191], we numerically solve the bootstrap to determine four-point correlation functions of the geometrical connect…
Four-point geometrical correlation functions in the two-dimensional -state Potts model: connections with the RSOS models
Yifei He, Linnea Grans-Samuelsson, Jesper Lykke Jacobsen +1
The "bootstrap determination" of the geometrical correlation functions in the two-dimensional Potts model proposed in a paper [arXiv:1607.07224] was later shown in [arXiv:1809.0219…
The O(N) S-matrix Monolith
Lucía Córdova, Yifei He, Martin Kruczenski +1
We consider the scattering matrices of massive quantum field theories with no bound states and a global symmetry in two spacetime dimensions. In particular we explore the sp…
A note on the S-matrix bootstrap for the 2d O(N) bosonic model
Yifei He, Andrew Irrgang, Martin Kruczenski
In this work we apply the S-matrix bootstrap maximization program to the 2d bosonic O(N) integrable model which has N species of scalar particles of mass m and no bound states. Sin…
Minimal area surfaces in AdS_{n+1} and Wilson loops
Yifei He, Changyu Huang, Martin Kruczenski
The AdS/CFT correspondence relates the expectation value of Wilson loops in N=4 SYM to the area of minimal surfaces in AdS_5 In this paper we consider minimal area surfaces in gene…
Minimal area surfaces in AdS through integrability
Yifei He, Martin Kruczenski
Minimal area surfaces in AdS ending on a given curve at the boundary are dual to planar Wilson loops in N=4 SYM. In previous work it was shown that the problem of finding such…
Minimal area surfaces dual to Wilson loops and the Mathieu equation
Changyu Huang, Yifei He, Martin Kruczenski
The AdS/CFT correspondence relates Wilson loops in N=4 SYM to minimal area surfaces in space. Recently, a new approach to study minimal area surfaces in $AdS_3 \s…
