Exciton Dynamics in Layered Halide Perovskite Light‐Emitting Diodes

Advanced Materials, EarlyView.
This review discusses the exciton dynamics in layered halide perovskitelight‐emitting diodes (PeLEDs). It opens with a summary of the structural and photophysical aspects, followed by an exploration of controlling dimensionality and cascade exciton transfer in quasi‐2D PeLEDs.

Functional renormalization group and conformal invariance in cold atoms

EPJ Web of Conferences, 2010
We present an application of a field-theoretic functional renormalization group technique to fewbody (vacuum) physics of nonrelativistic atoms near a Feshbach resonance.

UV completion of extradimensional Yang-Mills theory for Gauge-Higgs unification

SciPost Physics, 2023
The $SU(N)$ Yang-Mills theory in $\mathbb R^4\times S^1$ spacetime is studied as a simple toy model of Gauge-Higgs unification. The theory is perturbatively nonrenormalizable but could be formulated as an asymptotically safe theory, namely a ...

Renormalization Group Computation of Correlation Functions and Particle Densities [PDF]

Phys.Lett.A 284(2001) 6-11, 2000
We show that the Renormalization Group formalism allows to compute with accuracy the zero temperature correlation functions and particle densities of quantum systems.

Renormalization group invariant average momentum of non-singlet parton densities [PDF]

, 1999
We compute, within the Schr\"odinger functional scheme, a renormalization group invariant renormalization constant for the first moment of the non-singlet parton distribution function.

Ultrafast Anisotropic Optical‐Gap Shift in Low‐Symmetry Layered GeS

Advanced Optical Materials, EarlyView.
This study reveals ultrafast, anisotropic optical‐gap shift dynamics in GeS. Optical excitation induces a significant redshift in the polarization along the zigzag direction, about three times greater than that along the perpendicular armchair direction.

Four Loop Scalar ϕ4 Theory Using the Functional Renormalization Group †

Universe, 2019
We work with a symmetric scalar theory with quartic coupling in 4-dimensions. Using a 2PI effective theory and working at 4 loop order, we renormalize with a renormalization group method. All divergences are absorbed by one bare coupling constant and one

Efimov physics from the functional renormalization group

, 2012
Few-body physics related to the Efimov effect is discussed using the functional renormalization group method. After a short review of renormalization in its modern formulation we apply this formalism to the description of scattering and bound states in ...
