Construction of Frames on the Heisenberg Groups
Analysis and Geometry in Metric Spaces, 2020 In this paper, we present a construction of frames on the Heisenberg group without using the Fourier transform. Our methods are based on the Calderón-Zygmund operator theory and Coifman’s decomposition of the identity operator on the Heisenberg group ...

Advanced Science, EarlyView.A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Unusual Thermal Transport in Few‐Layer Van der Waals Antiferromagnet CrOCl
Advanced Science, EarlyView.Thermal transport serves as an ultra‐sensitive probe for detecting the magnetic order in 2D materials. Using the suspended thermal bridge method enhanced by Wheatstone bridges, it is, for the first time, observed anomalous critical behavior in few‐layer CrOCl near its Néel temperature.

Finite Heisenbeg Groups and Seiberg Dualities in Quiver Gauge Theories
, 2006 A large class of quiver gauge theories admits the action of finite Heisenberg groups of the form Heis(Z_q x Z_q). This Heisenberg group is generated by a manifest Z_q shift symmetry acting on the quiver along with a second Z_q rephasing (clock) generator

Geometric Hardy and Hardy–Sobolev inequalities on Heisenberg groups
Bulletin of Mathematical Sciences, 2020 In this paper, we present geometric Hardy inequalities for the sub-Laplacian in half-spaces of stratified groups. As a consequence, we obtain the following geometric Hardy inequality in a half-space of the Heisenberg group with a sharp constant: ∫ℍ ...

Gradings and Symmetries on Heisenberg type algebras [PDF]
Linear Algebra Appl. 458 (2014), 463-502, 2014 We describe the fine (group) gradings on the Heisenberg algebras, on the Heisenberg superalgebras and on the twisted Heisenberg algebras. We compute the Weyl groups of these gradings. Also the results obtained respect to Heisenberg superalgebras are applied to the study of Heisenberg Lie color algebras.

Advanced Science, EarlyView.Precise tuning of interlayer magnetic coupling in two‐dimensional bilayers enables control over altermagnetic and PT‐symmetric antiferromagnetic phases. This dual‐phase platform yields two intrinsic Hall responses: a Berry curvature–driven linear anomalous Hall effect and a quantum metric–induced second‐order nonlinear anomalous Hall effect ...

Bishop equations of Smarandache TM₁ curves of biharmonic B-slant helices in Heis³
Boletim da Sociedade Paranaense de Matemática, 2014 In this paper, we study Bishop equations for Smarandache TM₁ curves of biharmonic B-slant helices according to Bishop frame in the Heisenberg group Heis³.

Nonnegative kernels and $1$-rectifiability in the Heisenberg group [PDF]
, 2016 Let $E$ be an $1$-Ahlfors regular subset of the Heisenberg group $\mathbb{H}$. We prove that there exists a $-1$-homogeneous kernel $K_1$ such that if $E$ is contained in a $1$-regular curve the corresponding singular integral is bounded in $L^2(E ...
