Discovery of a New Phase in Thin Flakes of KV3Sb5 under Pressure
Advanced Science, EarlyView.The discovery of an unexpected new phase is reported in thin flake of KV3Sb5 under pressure. The new phase, alongside the CDW and superconducting phases, reveals an intriguing interplay between various novel phases in the kagome system. These findings suggest that this phase is related to nematicity, showcasing the kagome system's potential for ...

Functional Renormalization Group flows on Friedman-Lema\^{\i}tre-Robertson-Walker backgrounds [PDF]
, 2017 We reanalyze the construction of the gravitational functional renormalization group equation tailored to the Arnowitt-Deser-Misner formulation emphasizing its connection to the covariant formulation.

Functional renormalization group study of the Anderson–Holstein model
New Journal of Physics, 2014 We present a comprehensive study of the spectral and transport properties in the Anderson–Holstein model both in and out of equilibrium using the functional renormalization group (fRG).

Truncated-Unity Functional Renormalization Group for Multiband Systems With Spin-Orbit Coupling
Frontiers in Physics, 2018 Although the functional renormalization group (fRG) is by now a well-established method for investigating correlated electron systems, it is still undergoing significant technical and conceptual improvements.

Functional renormalization group for quantized anharmonic oscillator
, 2010 Functional renormalization group methods formulated in the real-time formalism are applied to the $O(N)$ symmetric quantum anharmonic oscillator, considered as a $0+1$ dimensional quantum field-theoric model, in the next-to-leading order of the gradient ...

Realizing Intrinsically Ultralow and Glass‐Like Thermal Transport via Chemical Bonding Engineering
Advanced Science, EarlyView.Lattice thermal conductivity can be effectively suppressed by introducing a S2 − anion into the bridging position between the Ag–Ag bond in the Ag6 octahedron, which weakens the Ag–Ag bond within the octahedral structure and enhances phonon‐phonon scattering rates. Abstract Crystals exhibiting glass‐like and low lattice thermal conductivity (κL$\kappa_{

Low Energy Thresholds and the Renormalization Group in the MSSM [PDF]
Phys.Lett. B348 (1995) 451-456, 1994 We derive the 1-loop Renormalization Group Equations for the parameters of the Minimal Supersymmetric Standard Model (MSSM) taking into account the successive decoupling of each sparticle below its threshold. This is realized by a step function at the level of each graph contributing to the Renormalization Group Equations.

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 ...
