Large analytical functional bootstrap I: 1D CFTs and total positivity
Zhijin Li
We initiate the analytical functional bootstrap study of conformal field theories with large limits. In this first paper we particularly focus on the 1D vector bootstrap…
Bootstrapping conformal QED
Soner Albayrak, Rajeev S. Erramilli, Zhijin Li +2
We present the results of a conformal bootstrap study of the presumed unitary IR fixed point of quantum electrodynamics in three dimensions (QED) coupled to two-compone…
Conformality and self-duality of QED
Zhijin Li
We study the IR phase of three dimensional quantum electrodynamics (QED) coupled to flavors of two-component Dirac fermions, which has been controversial for decades. T…
Symmetries of conformal correlation functions

A program of wide interest in modern conformal bootstrap studies is to numerically solve general conformal field theories, based on a critical assumption that the dynamics is encod…
Searching for gauge theories with the conformal bootstrap
Zhijin Li, David Poland
Infrared fixed points of gauge theories provide intriguing targets for the modern conformal bootstrap program. In this work we provide some preliminary evidence that a family of ga…

Three-dimensional conformal field theories (CFTs) with slightly broken higher spin symmetry provide an interesting laboratory to study general properties of CFTs and their roles in…

Zhijin Li
We bootstrap the deconfined quantum critical point (DQCP) and 3D Quantum Electrodynamics (QED) coupled to flavors of two-component Dirac fermions. We show the lattice and…

Anna Mîra, Yohan Payan, Ann-Katherine Carton +4
Mammography is currently the primary imaging modality for breast cancer screening and plays an important role in cancer diagnostics. A standard mammographic image acquisition alway…

Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We show that a new class of helical phase inflation models can be simply realized in minimal supergravity, wherein the inflaton is the phase component of a complex field and its po…

The supergravity (SUGRA) theories with exact global symmetry or shift symmetry in Kähler potential provide the natural frameworks for inflation. However, the quadratic infla…

No-Scale Ripple Inflation Revisited
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We revisit the no-scale ripple inflation model, where no-scale supergravity is modified by an additional term for the inflaton field in the Kahler potential. This term not only bre…
