The ferroelectric photo ground state of SrTiO3: Cavity materials engineering
(National Academy of Sciences, 2021-08-03)
Optical cavities confine light on a small region in space, which can result in a strong coupling of light with materials inside the cavity. This gives rise to new states where quantum fluctuations of light and matter can ...
Interplay of Topological States on TI/TCI Interfaces
(MDPI, 2020-10-10)
Based on first-principles calculations, we study electronic structure of interfaces between a Z2 topological insulator (TI) SnBi2Te4 and a topological crystalline insulator (TCI) SnTe. We consider two interface models ...
A Dissolution Model of Alite Coupling Surface Topography and Ions Transport under Different Hydrodynamics Conditions at Microscale
(Elsevier, 2021-04)
Portland cement is the most produced material in the world. The hydration process of cement consists of a group of complex chemical reactions. In order to investigate the mechanism of cement hydration, it is vital to study ...
Fabrication of a Novel Magnetic Topological Heterostructure and Temperature Evolution of its Massive Dirac Cone
(Nature, 2020-09-24)
Materials that possess nontrivial topology and magnetism is known to exhibit exotic quantum phenomena such as the quantum anomalous Hall effect. Here, we fabricate a novel magnetic topological heterostructure Mn4Bi2Te7/Bi2Te3 ...
Microcavity phonon polaritons from the weak to the ultrastrong phonon–photon coupling regime
(Nature Research, 2021-10-27)
[EN]Strong coupling between light and matter can be engineered to influence their properties and behaviour. Here, the authors demonstrate the evolution from weak to ultrastrong coupling of microcavity modes and optical ...
The Bloch point 3D topological charge induced by the magnetostatic interaction.
(Nature Research, 2021-11-05)
[EN]A hedgehog or Bloch point is a point-like 3D magnetization configuration in a ferromagnet. Regardless of widely spread treatment of a Bloch point as a topological defect, its 3D topological charge has never been ...
Chemistry in Quantum Cavities: Exact Results, the Impact of Thermal Velocities, and Modified Dissociation
(American Chemical Society, 2020-09-17)
In recent years tremendous progress in the field of lightmatter interactions has unveiled that strong coupling to the modes of an optical cavity can alter chemistry even at room temperature. Despite these impressive advances, ...
Direct Observation of Desorption of a Melt of Long Polymer Chains
(Nature, 2020-08-28)
Tuning the thermodynamic state of a material has a tremendous impact on its performance. In the case of polymers placed in proximity of a solid wall, this is possible by annealing above the glass transition temperature, ...
Tunable Photodetectors via In Situ Thermal Conversion of TiS3 to TiO2
(MDPI, 2020-04-09)
In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation ...
Out-of-Plane Transport of 1T-TaS2/Graphene-Based van der Waals Heterostructures
(American Chemical Society, 2021-07-27)
Due to their anisotropy, layered materials are excellent candidates for studying the interplay between the inplane and out-of-plane entanglement in strongly correlated systems. A relevant example is provided by 1T-TaS2, ...
