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…
Lightcone expansions of conformal blocks in closed form
Wenliang Li
We present new closed-form expressions for 4-point scalar conformal blocks in the s- and t-channel lightcone expansions. Our formulae apply to intermediate operators of arbitrary s…
Coupled density-spin Bose-Einstein condensates dynamics and collapse in systems with quintic nonlinearity
Jing Li, Boris A. Malomed, Wenliang Li +2
We investigate the effects of spin-orbit coupling and Zeeman splitting on the coupled density-spin dynamics and collapse of the Bose-Einstein condensate driven by the quintic self-…
Closed-form expression for cross-channel conformal blocks near the lightcone
Wenliang Li
In the study of conformal field theories, conformal blocks in the lightcone limit are fundamental to the analytic conformal bootstrap method. Here we consider the lightcone limit o…
Character Integral Representation of Zeta function in AdS: II. Application to partially-massless higher-spin gravities
Thomas Basile, Euihun Joung, Shailesh Lal +1
We compute the one-loop free energies of the type-A and type-B higher-spin gravities in -dimensional anti-de Sitter (AdS) spacetime. For large and…

Thomas Basile, Euihun Joung, Shailesh Lal +1
The zeta function of an arbitrary field in -dimensional anti-de Sitter (AdS) spacetime is expressed as an integral transform of the corresponding representation ch…
Non-Relativistic Limits of Colored Gravity in Three Dimensions
Euihun Joung, Wenliang Li
The three-dimensional non-relativistic isometry algebras, namely Galilei and Newton-Hooke algebras, are known to admit double central extensions, which allows for non-degenerate bi…
Exclusive Backward-Angle Omega Meson Electroproduction
Wenliang Li
This work is a pioneering study of backward-angle omega cross sections through the exclusive 1H(e,e'p)omega reaction using the missing mass reconstruction technique. The extracted…
New method for the conformal bootstrap with OPE truncations
Wenliang Li
We investigate two aspects of conformal field theories. In the first part, we study the general 4-point correlator of identical scalars around the fully crossing symmetric point $u…
Repulsive Fermi polarons with negative effective mass
Wenliang Li, Xiaoling Cui
Recent LENS experiment on a 3D Fermi gas has reported a negative effective mass () of Fermi polarons in the strongly repulsive regime. There naturally arise a question wheth…
Inverse Bootstrapping Conformal Field Theories
Wenliang Li
We propose a novel approach to study conformal field theories (CFTs) in general dimensions. In the conformal bootstrap program, one usually searches for consistent CFT data that sa…
Electron correlation in beryllium: Effects in ground state, short-pulse photoionization and time-delay studies
Juan J. Omiste, Wenliang Li, Lars Bojer Madsen
We apply a three-dimensional (3D) implementation of the time-dependent restricted-active-space self-consistent-field (TD-RASSCF) method to investigate effects of electron correlati…
On the absence of the Boulware-Deser ghost in novel graviton kinetic terms
Wenliang Li
Using novel nonlinear kinetic terms for gravitons, a large class of bi-gravity models were constructed, which are potentially free of the Boulware-Deser (BD) ghost. In this work, w…
Unifying Ghost-Free Lorentz-Invariant Lagrangians
Wenliang Li
We present the details of the novel framework for Lagrangian field theories that are Lorentz-invariant and lead to at most second order equations of motion. The use of antisymmetri…
A unifying framework for ghost-free Lorentz-invariant Lagrangian field theories
Wenliang Li
We propose a framework for Lorentz-invariant Lagrangian field theories where Ostrogradsky's scalar ghosts could be absent. A key ingredient is the generalized Kronecker delta. The…
Novel nonlinear kinetic terms for gravitons

A set of novel derivative terms for spin-2 fields are proposed. They are the wedge products of curvature two-forms and vielbeins. In this work, we investigate the properties of nov…

Elias Kiritsis, Wenliang Li, Francesco Nitti
The holographic formalism is applied to the calculation of the effective potential for the scalar glueball operator. Three different versions of this operator are defined, and for…

Euihun Joung, Wenliang Li, Massimo Taronna
We examine the generic theory of a partially massless (PM) spin-two field interacting with gravity in four dimensions from a bottom-up perspective. By analyzing the most general fo…
