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 ...

(2015-05-08)
Esta memoria recoge el estudio de laboratorio de propiedades químico físicas de partículas submicrométricas representativas de aerosoles troposféricos de origen natural y antropogénico; sistemas de interés en la química y ...
Development and applications of semicrystalline polymers: from shape memory to self-healing materials
(2017-02-10)
Las exigencias y comodidades del día a día hacen que el mundo en el que vivimos sea cada vez más automatizado y tecnológico, habiendo cada vez más interés en tener aparatos y materiales capaces de actuar por sí mismos. En ...
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 ...
Experimental implementation of precisely tailored light-matter interaction via inverse engineering
(Springer Nature Limited, 2021-09-14)
Accurate and efficient quantum control in the presence of constraints and decoherence is a requirement and a challenge in quantum information processing. Shortcuts to adiabaticity, originally proposed to speed up the slow ...
