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 ...

Totally smooth renormings [PDF]
arXiv, 2018 We study the problem of totally smooth renormings of Banach spaces and provide such renormings for spaces which are weakly compactly generated. We also consider renormings for $(a,B,c)$-ideals.

Renormalization group equations and integrability in Hamiltonian systems
, 1998 We investigate Hamiltonian systems with two degrees of freedom by using renormalization group method. We show that the original Hamiltonian systems and the renormalization group equations are integrable if the renormalization group equations are ...

The analytic renormalization group
Nuclear Physics B, 2016 Finite temperature Euclidean two-point functions in quantum mechanics or quantum field theory are characterized by a discrete set of Fourier coefficients $G_{k}$, $k\in\mathbb Z$, associated with the Matsubara frequencies $ _{k}=2 k/ $. We show that analyticity implies that the coefficients $G_{k}$ must satisfy an infinite number of model ...

Advanced Science, EarlyView.The resonant energy of the A and B exciton of the new 2D material, monolayer MoSi2N4, is found to be 2.18 and 2.34 eV, respectively, indicating a spin‐splitting energy of ≈160 meV. Complex and diverse exciton dynamics are observed. The work has a profound influence on the future developments of MoSi2N4‐based optoelectronic devices and the synthesis of ...

Time evolution as refining, coarse graining and entangling
New Journal of Physics, 2014 We argue that refining, coarse graining and entangling operators can be obtained from time evolution operators. This applies in particular to geometric theories, such as spin foams.

A new method that automatically regularizes scattering amplitudes
Journal of Physics Communications, 2023 We present a new regularization procedure called autoregularization . The new procedure regularizes the divergences, encountered previously in a scattering process, using the intrinsic scale of the process.

Renormalised singular stochastic PDEs [PDF]
arXiv, 2021 Extended decorations on naturally decorated trees were introduced in the work of Bruned, Hairer and Zambotti on algebraic renormalization of regularity structures to provide a convenient framework for the renormalization of systems of singular stochastic PDEs within that setting.

Renormalization group approach to matrix models via noncommutative space
, 2012 We develop a new renormalization group approach to the large-N limit of matrix models. It has been proposed that a procedure, in which a matrix model of size (N-1) \times (N-1) is obtained by integrating out one row and column of an N \times N matrix ...

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_{
