Advanced Science, EarlyView.The bonding hierarchy in X6Re6S8I8 (X = Rb, Cs) promotes phonon localization, generating extensive discrete phonon flat bands that redefine the lower bounds of lattice thermal conductivity in crystals. Abstract Within the unified theoretical framework for thermal transport, the inherent interplay between coherent tunneling and propagative phonon ...

Materials Selection Principles for Designing Electro‐Thermal Neurons
Advanced Electronic Materials, EarlyView.Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...

Exact flow equation for the divergence functional
Physics Letters B, 2023 An exact functional renormalization group flow equation is derived for the divergence functional which is a generalization of the Kullback-Leibler divergence to quantum field theories in the Euclidean domain.

Physical Review Research, 2023 Active matter is not only relevant to living matter and diverse nonequilibrium systems, but also constitutes a fertile ground for novel physics. Indeed, dynamic renormalization group (DRG) analyses have uncovered many new universality classes (UCs) in ...

The Functional Renormalization Group in Quantum Gravity
, 2023 The gravitational asymptotic safety program envisions a high-energy completion of the gravitational interactions by an interacting renormalization group fixed point, the Reuter fixed point. The primary tool for investigating this scenario are functional renormalization group equations, foremost the Wetterich equation.

Correlated starting points for the functional renormalization group [PDF]
Physical Review B, 2015 We present a general frame to extend functional renormalization group (fRG) based computational schemes by using an exactly solvable interacting reference problem as starting point for the RG flow. The systematic expansion around this solution accounts for a non-perturbative inclusion of correlations.
