High Energy Physics - Theory Papers of the Week

We introduce a multi-trace eigenstate thermalization hypothesis, an extension of ETH that governs connected correlations of operator matrix elements with arbitrary index structures, including several disjoint index cycles.

We investigate general properties of quasi-topological theories of gravity involving infinite towers of polynomial densities and of their regular vacuum black hole solutions.

We study the pinning-field line defect in the critical $\mathrm{O}(N)$ model at finite temperature, describing a static symmetry-breaking impurity at a quantum critical point.

We develop and validate a physics-informed neural network (PINN) framework for computing the tidal Love numbers of black holes directly from their perturbation equations.

In this thesis, we study classical black hole scattering, systematically including spin---an important feature of real astrophysical systems---to describe Kerr black hole dynamics.

We describe certain large $N$ decoupling limits where families of the saddles decouple from the rest to give the gravity duals of certain higher-dimensional field theories.

We show that the convergence region of the QNM representation of the retarded Green's function of the Kerr spacetime is set by complex-time bouncing singularities, as in our previous work for the Schwarzschild case.

We study thermal two- and three-point functions of scalar primaries in holographic CFTs dual to AdS black branes.

We introduce a recursion based on hidden zeros that reconstructs complete tree level scattering amplitudes and one-loop integrands at generic kinematics.

We construct the Hilbert space of a closed universe of fixed topology in anti-de Sitter (AdS) and de Sitter (dS) Jackiw-Teitelboim (JT) gravity from the gravitational path integral.

Can the geometry transverse to M2-branes capture effects that are exponentially small in their three-sphere ($S^3$) partition function? We investigate this question by extending beyond constant maps the proposal that M2-brane observables are encoded by equivariant topological strings on the transverse Calabi-Yau fourfold (CY$_4$).

We develop a numerical conformal bootstrap for two-dimensional CFTs with $c>1$ based on Virasoro conformal blocks, computed with Zamolodchikov's recursion and optimal polynomial interpolation.

Topological fluctuations in the quark-gluon plasma can generate local chiral imbalances whose spatial coherence remains difficult to access with conventional charge-separation measurements. We propose differential hyperon-pair spin correlations as a probe of both the strength and spatial organization of these fluctuations.

We construct an exact map between continuum fermion fields and lattice fields in 1+1 dimensions.

Because of the fermion doubling problem, it has been a longstanding challenge to describe a lattice algorithm for studying four-dimensional gauge theories coupled to chiral fermions.

In this paper, we study anomalies of $d$-dimensional topological quantum field theories (TQFTs) coupled to parameter spaces and their implications for ground-state degeneracies.

We show that the 7-brane data are encoded by additional lines in the GTP, which correspond to non-toric, non-compact divisors that we call exuberant divisors. Building on a local analysis of these divisors and on the associativity of the intersection product, we develop an algorithm that computes the triple intersection numbers, and hence the prepotential, directly from the combinatorial data of the GTP.

The large-order behavior of the expansion coefficients encodes physical information inaccessible at any finite order, so cosmological EFTs contain hidden data. Using resurgence analysis, we show how this information can be systematically extracted to recover exact and non-perturbative predictions from the perturbative expansion.

We derive the wave functional of the field on the nucleation slice from the half-bounce path integral, and use it to compute the root-mean-square quadrupole moment of a bubble at nucleation.

We apply the functional renormalization group to the worldsheet theory of the bosonic string.
