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 ...

Corner Transfer Matrix Algorithm for Classical Renormalization Group [PDF]

J. Phys. Soc. Jpn. 66 (1997) 3040, 1997
We report a real-space renormalization group (RSRG) algorithm, which is formulated through Baxter's corner transfer matrix (CTM), for two-dimensional (d = 2) classical lattice models. The new method performs the renormalization group transformation according to White's density matrix algorithm, so that variational free energies are minimized within a ...

Renormalization scheme dependence and renormalization group summation [PDF]

Canadian Journal of Physics, 2018
We consider logarithmic contributions to the free energy, instanton effective action, and Laplace sum rules in QCD that are a consequence of radiative corrections. Upon summing these contributions by using the renormalization group, all dependence on the renormalization scale parameter μ cancels.

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_{

General quartic β-function at three loops

Journal of High Energy Physics
We determine the three-loop MS ¯ $$ \overline{\textrm{MS}} $$ quartic β-function for the most general renormalisable four-dimensional theories. A general parametrisation of the β-function is compared to known β-functions for specific theories to fix all ...

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 ...

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 ...

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 ...

The Slow‐Rotating Nucleus of Comet C/2013 R1 (Lovejoy)

Astronomische Nachrichten, EarlyView.
ABSTRACT The close approach of comet C/2013 R1 (Lovejoy) allowed us to conduct an in‐depth study of the morphology of the inner coma. From the measurement of the dust emission structures expanding near the cometary nucleus in November–December 2013, we derived a slow rotation period of 47.8±1.2$$ 47.8\pm 1.2 $$ h.
