Increasing the number of topological nodal lines in semimetals via uniaxial pressure

Scientific Reports, 2021
The application of pressure has been demonstrated to induce intriguing phase transitions in topological nodal-line semimetals. In this work we analyze how uniaxial pressure affects the topological character of BaSn $$_2$$ 2 , a Dirac nodal-line semimetal

Topological phase transition at the interface of a topological with a conventional insulator

Journal of Physics: Condensed Matter, 2020
Abstract We study the topological states which appear at the interface between a topological insulator (TI) and a conventional insulator (CI) using effective Hamiltonians which accurately describe the band structure of the Bi 2 Se 3 ...

Topological phase transition and texture inversion in a tunable topological insulator [PDF]

, 2011
The recently discovered three-dimensional or bulk topological insulators are expected to exhibit exotic quantum phenomena. It is believed that a trivial insulator can be twisted into a topological state by modulating the spin-orbit interaction or the ...

Interaction-induced Metal to Topological Insulator Transition

, 2023
By means of exact diagonalizations, the Bernevig-Hughes-Zhang model at quarter-filling in the limit of strong Hubbard on-site repulsion is investigated. We find that the non-interacting metallic state will be turned into a Chern insulator with saturated ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

TRANSITIVITY IN POINT-FREE TOPOLOGY [PDF]

Bulletin of the Australian Mathematical Society, 2009
AbstractThe main purpose of this paper is to develop a point-free notion of topological transitivity. First, we define transitive frame maps and transitive completely prime filters inFrm, the category of frames and frame maps. Then we discuss the relationship between these notions inFrmand the notions of topological transitive and transitive points ...

Predicting a new phase (T′′) of two-dimensional transition metal di-chalcogenides and strain-controlled topological phase transition

, 2016
Single layered transition metal dichalcogenides have attracted tremendous research interest due to their structural phase diversities. By using a global optimization approach, we have discovered a new phase of transition metal dichalcogenides (labelled ...

Topological phase transition of Bi

, 2020
Compared with Bi2Se3 with its Dirac point in the bulk gap, the Dirac point of Bi2Te3 is in the valence band, then it is generally considered that it is difficult to observe the topological phase transition course in the Bi2Te3 system via nonmagnetic ...

Disorder-Induced Topological State Transition in Photonic Metamaterials [PDF]

, 2017
The topological state transition has been widely studied based on the quantized topological band invariant such as the Chern number for the system without intense randomness that may break the band structures.

Topological Transition of Superconductivity in Dirac Semimetal Nanowire Josephson Junctions [PDF]

, 2021
We report the topological transition by gate control in a Cd3As2 Dirac semimetal nanowire Josephson junction with diameter of about 64 nm. In the electron branch, the quantum confinement effectenforces the surface band into a series of gapped subbands ...
