Instanton effects in quark form factor and quark-quark scattering at high energy

, 2004
The nonperturbative effects in the high-energy processes involving strongly interacting particles are studied within the instanton liquid model of the QCD vacuum (ILM) by using the Wilson integral framework.

Nonperturbative effects on radiative energy loss of heavy quarks [PDF]

Journal of High Energy Physics, 2020
Abstract The radiative energy loss of fast partons traveling through the quark-gluon plasma (QGP) is commonly studied within perturbative QCD (pQCD). Nonperturbative (NP) effects, which are expected to become important near the critical temperature, have been much less investigated.

Sequestering in String Compactifications

, 2010
We study the mediation of supersymmetry breaking in string compactifications whose moduli are stabilized by nonperturbative effects. We begin with a critical review of arguments for sequestering in supergravity and in string theory.

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

Advanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...

Floquet‐Engineered Noise‐Resilient Terahertz Receiver with Modular Phased Array Architecture for Scalable Chip‐Scale Communication

Advanced Photonics Research, EarlyView.
Overcoming the bandwidth, latency, and power constraints of wired interconnects in multicore processing units, this work introduces a terahertz wireless solution featuring a dual‐carrier modular phased‐array transmitter and a novel 2D semiconductor quantum‐well nanoreceiver.

Quantum effective actions from nonperturbative worldline dynamics

, 2005
We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we compute the effective action for a super-renormalizable field theory with

Nonperturbative and perturbative aspects of photo- and electroproduction of vector mesons [PDF]

, 2006
We discuss various aspects of vector meson production, first analysing the interplay between perturbative and nonperturbative aspects of the QCD calculation.

Hawking radiation of extended objects

Journal of High Energy Physics, 2020
We compute the effects on the temperature and precise spectrum of Hawking radiation from a Schwarzschild black hole when the emitted object is taken to be spatially extended.

The Källén-Lehmann representation in de Sitter spacetime

Journal of High Energy Physics, 2023
We study two-point functions of symmetric traceless local operators in the bulk of de Sitter spacetime. We derive the Källén-Lehmann spectral decomposition for any spin and show that unitarity implies its spectral densities are nonnegative.

Laser‐Driven Charge‐Transfer Dynamics in the Quaterthiophene–Fullerene Donor/Acceptor Interface

ChemPhotoChem, EarlyView.
This ab initio study investigates laser‐induced charge‐transfer in a quaterthiophene/fullerene complex at varying intensities of the external pulse. Pulses above 3 GW cm−2 are needed to trigger charge transfer, which is enabled by vibrations in the donor. Under stronger field intensities, transient effects in the system prevail.
