Anomalous dimensions of partially-conserved higher-spin currents from conformal field theory: bosonic theories
Yongwei Guo, Wenliang Li
In the free scalar conformal field theory, there exist conserved and partially-conserved higher-spin currents. We study their anomalous dimensions associated with …
Solving anharmonic oscillator with null states: Hamiltonian bootstrap and Dyson-Schwinger equations
Yongwei Guo, Wenliang Li
As basic quantum mechanical models, anharmonic oscillators are recently revisited by bootstrap methods. An effective approach is to make use of the positivity constraints in Hermit…
Taming Dyson-Schwinger equations with null states
Wenliang Li
In quantum field theory, the Dyson-Schwinger equations are an infinite set of coupled equations relating -point Green's functions in a self-consistent manner. They have found im…
Null bootstrap for non-Hermitian Hamiltonians
Wenliang Li
A stable physical system has an energy spectrum that is bounded from below. For quantum systems, the dangerous states of unboundedly low energies should decouple and become null. W…
Ising model close to
Wenliang Li
The critical Ising model is described by an exactly solvable Conformal Field Theory (CFT). The deformation to is a relatively simple system at strong coupling outside…
Factorized lightcone expansion of conformal blocks
Wenliang Li
We present a factorized decomposition of 4-point scalar conformal blocks near the lightcone, which applies to arbitrary intermediate spin and general spacetime dimensions. Then we…
