Disorder-induced topological transitions in a multilayer topological insulator

Physical Review B
We examine the impact of non-magnetic disorder on the electronic states of a multilayer structure comprising layers of both topological and conventional band insulators. Employing the Burkov-Balents model with renormalized tunneling parameters, we generate phase diagrams correlating with disorder, demonstrating that non-magnetic disorder can induce ...

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

Advanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Topological Lifshitz transitions [PDF]

Low Temperature Physics, 2017
Different types of Lifshitz transitions are governed by topology in momentum space. They involve the topological transitions with the change of topology of Fermi surfaces, Weyl and Dirac points, nodal lines, and also the transitions between the fully gapped states.

Exchange field-induced topological phase transition in ultrathin films of three-dimension topological insulators

, 2012
We investigate the topological phase transition in ultrathin films of three-dimension topological insulators, induced by a rotation of the exchange field.

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Topological Phase Transitions [PDF]

, 2019
This chapter aims to develop a systematic theory of topological phase transitions (TPTs) and explores a few typical examples, including (1) quantum phase transitions (QPTs), (2) galactic spiral structures, (3) electromagnetic eruptions on solar surface, (4) boundary-layer separation of fluid flows, and (5) interior separation of fluid flows.
