Bound polariton states in the Dicke–Ising model

Nanophotonics, Volume 14, Issue 11, Page 2053-2064, June 2025.
Abstract We present a study of hybrid light–matter excitations in cavity QED materials using the Dicke–Ising model as a theoretical framework. Leveraging linear response theory, we derive the exact excitations of the system in the thermodynamic limit.

All-multiplicity amplitudes in impulsive PP-waves from the worldline formalism

Journal of High Energy Physics
We use the worldline formalism to derive Bern-Kosower type Master Formulae for the tree-level scattering of a charged particle and an arbitrary number of photons on impulsive PP-waves, where the coupling of the PP-wave to matter is treated fully non ...

Quantum light: creation, integration, and applications

Nanophotonics, Volume 14, Issue 11, Page 1683-1686, June 2025.
Abstract In today’s rapidly evolving quantum landscape, the generation and manipulation of quantum light not only represent fundamental challenges but also herald unprecedented opportunities in communication, computing, sensing, and imaging. This special issue brings together a collection of contributions that span the entire journey, from the creation

Renormalization of the 2PI Hartree-Fock approximation on de Sitter background in the broken phase

, 2012
The infrared effects for light minimally coupled scalar fields with quartic self-interaction in de Sitter space is investigated using the 2PI effective action formalism.

Nonperturbative effects in deformation quantization

, 2000
The Cattaneo-Felder path integral form of the perturbative Kontsevich deformation quantization formula is used to explicitly demonstrate the existence of nonperturbative corrections to na\" ve deformation quantization.

Computation of Time‐Resolved Nonlinear Electronic Spectra From Classical Trajectories

WIREs Computational Molecular Science, Volume 15, Issue 3, May/June 2025.
Stimulated emission contribution to the two‐dimensional electronic spectrum of pyrazine at a waiting time of 60 fs as a function of the excitation and emission frequencies. ABSTRACT A variety of time‐resolved spectroscopic techniques employing femtosecond pump and probe pulses are nowadays widely used to unravel the fundamental mechanisms of ...

Complex eigenvalue instantons and the Fredholm determinant expansion in the Gross-Witten-Wadia model

Journal of High Energy Physics
We study the leading nonperturbative corrections to the strong-coupling (ungapped) phase of the Gross-Witten-Wadia (GWW) integral over unitary matrices, to one-loop order.

Elliptic genus derivation of 4d holomorphic blocks

Journal of High Energy Physics, 2018
We study elliptic vortices on ℂ × T 2 by considering the 2d quiver gauge theory describing their moduli spaces. The elliptic genus of these moduli spaces is the elliptic version of vortex partition function of the 4d theory. We focus on two examples: the

Semiholography for heavy ion collisions

, 2016
The formation of QGP in heavy ion collisions gives us a great opportunity for learning about nonperturbative dynamics of QCD. Semiholography provides a new consistent framework to combine perturbative and non-perturbative effects in a coherent way and ...

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking
