Lie groups locally isomorphic to generalized Heisenberg groups [PDF]
Proceedings of the American Mathematical Society, 2008 We classify connected Lie groups which are locally isomorphic to generalized Heisenberg groups. For a given generalized Heisenberg group N N

Dual Lie algebras of Heisenberg Poisson Lie groups
Tsukuba Journal of Mathematics, 1993 Starting point is an arbitrary Heisenberg Lie algebra \(L\) \(([L,L] = Z(L)\) with one-dimensional center \(Z(L)\)) and the set of its multiplicative Poisson structures. The authors study the dual Lie algebras induced on \(L\) by these structures.

The Harmonic Oscillator on the Heisenberg Group
Comptes Rendus. Mathématique, 2020 In this note we present a notion of harmonic oscillator on the Heisenberg group $\mathbf{H}_n$ which forms the natural analogue of the harmonic oscillator on $\mathbb{R}^n$ under a few reasonable assumptions: the harmonic oscillator on $\mathbf{H}_n ...

Phase diagram of a distorted kagome antiferromagnet and application to Y-kapellasite
npj Computational Materials, 2022 We investigate the magnetism of a previously unexplored distorted spin-1/2 kagome model consisting of three symmetry-inequivalent nearest-neighbor antiferromagnetic Heisenberg couplings J ⬡, J, and $$J^{\prime}$$ J ′ , and uncover a rich ground state ...

Multi-fixed point numerical conformal bootstrap: a case study with structured global symmetry
Journal of High Energy Physics, 2021 In large part, the future utility of modern numerical conformal bootstrap depends on its ability to accurately predict the existence of hitherto unknown non-trivial conformal field theories (CFTs). Here we investigate the extent to which this is possible

The Local Structure of the Cyclic Cohomology of Heisenberg Lie Groups
Journal of Functional Analysis, 1994 Let \(G\) be a connected, simply connected nilpotent Lie group of dimension \(n\) and \(S(G)\) the convolution algebra of the Schwartz functions. It is known [\textit{G. A. Elliott} and the authors, Cyclic cohomology for one- parameter smooth crossed products, Acta Math. 160, No.

Advances in Mathematics, 2023 In the paper under reviewing, by using the Fourier transformed Knapp-Stein intertwining operators, the authors study decomposability of representations induced from a character of the maximal parabolic subgroup with a Heisenberg group as its radical. A reductive Lie group \(G\) is Hermitian if its symmetric space \(K\backslash G\) is Hermitian.

Group theoretic approach to many-body scar states in fermionic lattice models
Physical Review Research, 2021 It has been shown [K. Pakrouski et al., Phys. Rev. Lett. 125, 230602 (2020)PRLTAO0031-900710.1103/PhysRevLett.125.230602] that three families of highly symmetric states are many-body scars for any spin-1/2 fermionic Hamiltonian of the form H_{0}+OT ...
