von Neumann spin measurements with Rashba fields
(IOP Publishing, 2014-01-10)
We show that dynamics in the spin-orbit coupling field simulate the von Neumann measurement of a particle spin. We demonstrate how the measurement influences the spin and coordinate evolution of a particle by comparing two ...
Temperature-and pH-Sensitive Nanohydrogels of Poly(N-Isopropylacrylamide) for Food Packaging Applications: Modelling the Swelling-Collapse Behaviour
(Public Library of Science, 2014-02)
Temperature-sensitive poly(N-isopropylacrylamide) (PNIPA) nanohydrogels were synthesized by nanoemulsion polymerization in water-in-oil systems. Several cross-linking degrees and the incorporation of acrylic acid as comonomer ...
Nanoscale shear cohesion between cement hydrates: The role of water diffusivity under structural and electrostatic confinement
(Elsevier, 2022-04)
[EN] The calcium silicate hydrate (C-S-H) controls most of the final properties of the cement paste, including its mechanical performance. It is agreed that the nanometer-sized building blocks that compose the C-S-H are ...
The effects of disorder in dimerized quantum magnets in mean field approximations
(IOP Publishing LTD, 2012-11-07)
We study theoretically the effects of disorder on Bose-Einstein condensates (BEC) of bosonic triplon quasiparticles in doped dimerized quantum magnets. The condensation occurs in a magnetic field, where the concentration ...
Stable Two-Dimensional Soliton Complexes in Bose-Einstein Condensates with Helicoidal Spin-Orbit Coupling
(IOP Publishing, 2020-10-08)
We show that attractive two-dimensional (2D) spinor Bose-Einstein condensates with helicoidal spatially periodic spin-orbit coupling (SOC) support a rich variety of stable fundamental solitons and bound soliton complexes. ...
Molecular Dynamics and Experimental Study on the Adhesion Mechanism of Polyvinyl Alcohol (PVA) Fiber in Alkali-Activated Slag/Fly Ash
(Elsevier, 2021-07)
This paper aims to study the adhesion mechanism of polyvinyl alcohol (PVA) fiber within alkali-activated slag/fly ash (AASF) matrix using molecular dynamics (MD) simulation in combination with systematic experimental ...
An Experimental Investigation of Ultraweak Photon Emission from Adult Murine Neural Stem Cells
(Nature, 2020-01-16)
Neurons like other living cells may have ultraweak photon emission (UPE) during neuronal activity. This study is aimed to evaluate UPE from neural stem cells (NSC) during their serial passaging and differentiation. We also ...
Interplay of Spin-Orbit Coupling and Coulomb Interaction in ZnO-Based Electron System
(Springer, 2021-05-26)
Spin-orbit coupling (SOC) is pivotal for various fundamental spin-dependent phenomena in solids and their technological applications. In semiconductors, these phenomena have been so far studied in relatively weak ...
An Innovative Approach for the Generation of Species of the Interstellar Medium
(Wiley, 2021-11-08)
[EN]The large amount of unstable species in the realm of interstellar chemistry drives an urgent need to develop efficient methods for the in situ generations of molecules that enable their spectroscopic characterizations. ...
Klein paradox for bosons, wave packets and negative tunnelling times
(Nature, 2020-11-05)
We analyse a little known aspect of the Klein paradox. A Klein-Gordon boson appears to be able to cross a supercritical rectangular barrier without being reflected, while spending there a negative amount of time. The ...
