Constructions of rotated lattice constellations in dimensions power of 3
(2018-09-01)
In this paper, we present the constructions of rotated ℤ3r-1-lattices, where r is a positive integer, via ℤ-modules of the ring of the integers ℤ [ζ3r+ζ 3r-1]. Our focus is on totally real number fields since the associated ...
Famílias de reticulados algébricos e reticulados ideais
(Universidade Estadual Paulista (Unesp), 2010-02-26)
Neste trabalho é feito um estudo sobre famílias de reticulados algébricos e reticulados ideais. Nosso principal objetivo é a construção de reticulados que são versões rotacioanadas de reticulados já conhecidos na literatura. ...

Algebraic constructions of rotated unimodular lattices and direct sum of Barnes-Wall lattices
(2020-01-01)
In this paper, we construct some families of rotated unimodular lattices and rotated direct sum of Barnes-Wall lattices BWn for n = 4, 8 and 16 via ideals of the ring of the integers azeta&2rq + ;zeta&2rq-1] for q = 3, 5 ...
Phase-separated vortex-lattice in a rotating binary Bose–Einstein condensate
(2019-06-15)
We study circularly-symmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional binary Bose–Einstein condensate (BEC) by introducing a weak quartic trap in one of the ...
Vortex-lattice formation in a spin-orbit coupled rotating spin-1 condensate
(2020-11-06)
We study the vortex-lattice formation in a rotating Rashba spin-orbit (SO) coupled quasi-two-dimensional (quasi-2D) hyper-fine spin-1 spinor Bose-Einstein condensate (BEC) in the x-y plane using a numerical solution of the ...

Symmetry-breaking vortex-lattice of a binary superfluid in a rotating bucket
(2020-02-06)
We study spontaneous-symmetry-broken phase-separated vortex lattice in a weakly interacting uniform rapidly rotating binary Bose superfluid contained in a quasi-two-dimensional circular or square bucket. For the inter-species ...
Rotated dn-lattices in dimensions power of 3
(2021-09-15)
In this work, we present constructions of families of rotated Dn-lattices which may be good for signal transmission over both Gaussian and Rayleigh fading channels. The lattices are obtained as sublattices of a family of ...
Vortex-lattice in a uniform Bose-Einstein condensate in a box trap
(2019-01-01)
We study numerically the vortex-lattice formation in a rapidly rotating uniform quasi-twodimensional Bose-Einstein condensate (BEC) in a box trap. We consider two types of boxes: square and circle. In a square-shaped 2D ...
