Renormalization group analysis for thermal turbulence

International Journal of Mathematics and Mathematical Sciences, 1997
Renormalization group theory is applied to thermal turbulence. Turbulent fluxes for the flow are accounted for by repeatedly recasting the governing equations with the smallest scales represented by effective larger scales.

The density-matrix renormalization group

, 2004
The density-matrix renormalization group (DMRG) is a numerical algorithm for the efficient truncation of the Hilbert space of low-dimensional strongly correlated quantum systems based on a rather general decimation prescription.

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering

Advanced Energy and Sustainability Research, EarlyView.
Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, EarlyView.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Renormalization group in super-renormalizable quantum gravity

European Physical Journal C: Particles and Fields, 2018
One of the main advantages of super-renormalizable higher derivative quantum gravity models is the possibility to derive exact beta functions, by making perturbative one-loop calculations.

Optimal renormalization and the extraction of strange quark mass from semi-leptonic $\tau$-decay

, 2017
We employ optimal renormalization group analysis to semi-leptonic $\tau$-decay polarization functions and extract the strange quark mass from their moments measured by the ALEPH and OPAL collaborations.

Quantum Anomalies in Condensed Matter

Advanced Physics Research, EarlyView.
Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

The Correlated Block Renormalization Group

, 1995
We formulate the standard real-space renormalization group method in a way which takes into account the correlation between blocks. This is achieved in a dynamical way by means of operators which reflect the influence on a given block of its neighbours ...

Surface Local Impurity Scattering as a Probe for Topological Kondo Insulators

Advanced Physics Research, EarlyView.
Impurity scattering smokes out topology! Recent discoveries in topological quantum materials have rekindled excitement for studying particle and high‐energy physics in a condensed matter physics laboratory. By using a minimal‐orbital correlated electron model, this study sheds light on the topological nature of a Kondo insulator via the local ...
