From locality to irregularity: introducing local quenches in massive scalar field theory

Journal of High Energy Physics, 2023
In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider the dynamics of excited local states in massive scalar field theory in an arbitrary spacetime dimension and generalize the well-known two ...

The complex sinh-Gordon model: form factors of descendant operators and current-current perturbations

Journal of High Energy Physics, 2019
We study quasilocal operators in the quantum complex sinh-Gordon theory in the form factor approach. The free field procedure for descendant operators is developed by introducing the algebra of screening currents and related algebraic objects.

Dimensionally continued Oppenheimer-Snyder gravitational collapse. I - solutions in even dimensions

, 1996
The extension of the general relativity theory to higher dimensions, so that the field equations for the metric remain of second order, is done through the Lovelock action.

Modular energy inequalities from relative entropy

Journal of High Energy Physics, 2018
We obtain new constraints for the modular energy of general states by using the monotonicity property of relative entropy. In some cases, modular energy can be related to the energy density of states and these constraints lead to interesting relations ...

Generalized Electromagnetism of Subdimensional Particles: A Spin Liquid Story [PDF]

, 2017
It has recently been shown that there exists a class of stable gapless spin liquids in 3+1 dimensions described by higher rank tensor U(1) gauge fields, giving rise to an emergent tensor electromagnetism.

The Little Hierarchy in Universal Extra Dimensions [PDF]

, 2006
In the standard model in universal extra dimensions (UED) the mass of the Higgs field is driven to the cutoff of the higher-dimensional theory. This re-introduces a small hierarchy since the compactification scale 1/R should not be smaller than the weak ...

Compactifying 5d superconformal field theories to 3d

Journal of High Energy Physics, 2021
Building on recent progress in the study of compactifications of 6d (1, 0) superconformal field theories (SCFTs) on Riemann surfaces to 4d N $$ \mathcal{N} $$ = 1 theories, we initiate a systematic study of compactifications of 5d N $$ \mathcal{N} $$ = 1

Numerical and Theoretical Study of a Monodisperse Hard-Sphere Glass Former [PDF]

, 2010
There exists a variety of theories of the glass transition and many more numerical models. But because the models need built-in complexity to prevent crystallization, comparisons with theory can be difficult.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
