Modular invariance and thermal effective field theory in CFT [PDF]
Journal of High Energy PhysicsWe use thermal effective field theory to derive that the coefficient of the first subleading piece of the thermal free energy, c 1, is equal to the coefficient of the subleading piece of the Casimir energy on S 1 × S d−2 for d ≥ 4.

Interplay between improved interaction rates and modified cosmological histories for dark matter
Frontiers in Physics, 2023 A novel particle has been and still is an intriguing option to explain the strong evidence for dark matter in our universe. To quantitatively predict the dark matter energy density, two main ingredients are needed: interaction rates and the history of ...

Thermal Effects in Ising Cosmology
Universe, 2023 We consider a real scalar field in de Sitter background and compute its thermal propagators. We propose that in a dS/CFT context, nontrivial thermal effects as seen by an ‘out’ observer can be encoded in the anomalous dimensions of the d=3 Ising model ...

Feynman rules for forced wave turbulence
Journal of High Energy Physics, 2023 It has long been known that weakly nonlinear field theories can have a late-time stationary state that is not the thermal state, but a wave turbulent state with a far-from-equilibrium cascade of energy.

Determining all thermodynamic transport coefficients for an interacting large N quantum field theory
Journal of High Energy Physics, 2023 Thermodynamic transport coefficients can be calculated directly from quantum field theory without requiring analytic continuation to real time. We determine all second-order thermodynamic transport coefficients for the uncharged N-component massless ...

Holographic thermal correlators: a tale of Fuchsian ODEs and integration contours
Journal of High Energy Physics, 2023 We analyze real-time thermal correlation functions of conserved currents in holographic field theories using the grSK geometry, which provides a contour prescription for their evaluation.

Real-time spin systems from lattice field theory
Journal of High Energy Physics, 2023 We construct a lattice field theory method for computing the real-time dynamics of spin systems in a thermal bath. This is done by building on previous work of Takano with Schwinger-Keldysh and functional differentiation techniques. We derive a Schwinger-

Spectral form factor of a quantum spin glass
Journal of High Energy Physics, 2022 It is widely expected that systems which fully thermalize are chaotic in the sense of exhibiting random-matrix statistics of their energy level spacings, whereas integrable systems exhibit Poissonian statistics.

Thermalization and chaos in a 1+1d QFT
Journal of High Energy Physics, 2023 We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. We find that our eigenstate spectrum satisfies Wigner-Dyson statistics and that the coefficients describing eigenstates in our basis satisfy ...
