Deformation of noncommutative quantum mechanics [PDF]

Journal of Mathematical Physics, 2016
In this paper, the Lie group GNCα,β,γ, of which the kinematical symmetry group GNC of noncommutative quantum mechanics (NCQM) is a special case due to fixed nonzero α, β, and γ, is three-parameter deformation quantized using the method suggested by Ballesteros and Musso [J. Phys. A: Math. Theor. 46, 195203 (2013)].

Atomistic mechanism of nucleation and growth of a face-centered orthogonal phase in small-sized single-crystalline Mo

Materials Research Letters, 2020
Phase transformation is an important deformation and blunting mechanism at the crack tip of body-centered cubic (BCC) metals. The BCC-to-face-centered orthogonal (FCO) transformation was only predicted by ab initio calculations.

Deformation evolution and deformation destabilization mechanism of fault-boundary slope dumping

Shuiwen dizhi gongcheng dizhi
In April 2017, a slope in Pingquan City, Hebei Province, China showed signs of large-scale sliding deformation after multiple excavations. Although the excavation revealed that the slope underwent toppling deformation, the surrounding rock strata are ...

Design by analysis of ductile failure and buckling in torispherical pressure vessel heads [PDF]

, 2007
Thin shell torispherical pressure vessel heads are known to exhibit complex elastic-plastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes ...

Vaidya Spacetime in Massive Gravity's Rainbow

, 2017
In this paper, we will analyze the energy dependent deformation of massive gravity using the formalism of massive gravity's rainbow. So, we will use the Vainshtein mechanism and the dRGT mechanism for the energy dependent massive gravity, and thus ...

Microstructure evolution and densification of sintered porous 2024 aluminum alloy compressed in a semi-solid state

Materials Research Express, 2021
The semi-solid powder forming (SSPF) as a promising technology has a complicated process, but the formation mechanism of that remains unclear. The study of semi-solid compression of porous materials is an effective method to investigate the SSPF.

Role of Fragment Higher Static Deformations in the Cold Binary Fission of $^{252}$Cf [PDF]

, 1998
We study the binary cold fission of $^{252}$Cf in the frame of a cluster model where the fragments are born to their respective ground states and interact via a double-folded potential with deformation effects taken into account up to multipolarity ...
