Quantum holonomies and the Heisenberg group [PDF]
Modern Physics Letters A, 2019 Quantum holonomies of closed paths on the torus [Formula: see text] are interpreted as elements of the Heisenberg group [Formula: see text]. Group composition in [Formula: see text] corresponds to path concatenation and the group commutator is a deformation of the relator of the fundamental group [Formula: see text] of [Formula: see text], making ...

Cr1/4NbSe2‐Single Crystal Growth and Evolution of Antiferromagnetic Correlated States
Advanced Science, EarlyView.High‐quality single crystals Cr1/4NbSe2 were synthesized and comprehensively characterized for the first time. Advanced structural, electronic, and magnetic measurements uncover a correlated antiferromagnetic state, resolving longstanding inconsistencies regarding magnetic behavior derived from earlier polycrystal studies.

One parameter family of S-tangent surfaces
Acta Scientiarum: Technology, 2015 In this paper, we study S-tangent surfaces according to Sabban frame in the Lorentzian Heisenberg group Heis³. We obtain differential equations about in terms of their geodesic curvatures in the Lorentzian Heisenberg group Heis³.

Fourier analysis on the Heisenberg group [PDF]
Proceedings of the National Academy of Sciences, 1977 We obtain a usable characterization of the (group) Fourier transform of 𝒮(H n ) (Schwartz space on the Heisenberg group). The characterization involves writing elements of [Formula: see text] as asymptotic series in Planck's constant. In the process,

The Cohomology of the Integer Heisenberg Groups
Journal of Algebra, 1996 A closed formula for the cohomology groups of the standard integer lattice in the simply-connected Heisenberg Lie group of dimension \(2n+1\), \(n\in\mathbb{Z}^+\) is given and a recursion relation involving \(n\) for these cohomology groups is provided.

Existence for (p, q) critical systems in the Heisenberg group
Advances in Nonlinear Analysis, 2019 This paper deals with the existence of entire nontrivial solutions for critical quasilinear systems (𝓢) in the Heisenberg group ℍn, driven by general (p, q) elliptic operators of Marcellini types.

Dioxygen Reduction at a Cu(I) Complex Supported by a Macrocyclic N3O Ligand System
Chemistry – A European Journal, EarlyView.A non‐reactive [CuI(14‐TMC)]+ complex is transformed to an efficient catalyst [CuI(14‐TMCO)]+ (TMCO = 4,8,12‐trimethyl‐1‐oxa‐4,8,12‐triazacyclotetradecane) for 4e−/4H+ reduction of O2 by N → O substitution. ABSTRACT CuI(14 TMCO) (1), involving a N3O‐macrocycle, reacts with O2 at cryogenic temperatures to yield an end‐on peroxodicopper(II) species.

Barley Leaf Area and Leaf Growth Rates Are Maximized during the Pre-Anthesis Phase
Agronomy, 2015 Leaf developmental traits are an important component of crop breeding in small-grain cereals. Surprisingly, little is known about the genetic basis for the differences in barley (Hordeum vulgare L.) leaf development. The two barley row-type classes, i.e.
