Chromatin Topological Transitions [PDF]
Progress of Theoretical Physics Supplement, 2011 (Received February 24, 2011)DNA transaction events occurring during a cell cycle (transcription, repair, replication)are always associated with severe topological constraints on the double helix. However, sincenuclear DNA is bound to various proteins (including histones) that control its accessibilityand 3D organization, these topological constraints ...

Topological transition on the conformal manifold [PDF]
Physical Review Research, 2020 Despite great successes in the study of gapped phases, a comprehensive understanding of the gapless phases and their transitions is still under developments. In this paper, we study a general phenomenon in the space of (1+1)$d$ critical phases with fermionic degrees of freedom described by a continuous family of conformal field theories (CFT), a.k.a ...

In-Plane Anisotropic Plasmons in Van Der Waals Thin Films of WTe2
IEEE Photonics Journal, 2022 Anisotropic plasmonic surface supports elliptic, hyperbolic and even flattened polaritons, which is quite interesting for the diffractionless and highly collimated propagation of infrared light at the nanoscale.

Negative refraction in twisted hyperbolic metasurfaces
Nanophotonics, 2021 Hyperbolic metasurfaces with unique dispersion properties can manipulate light–matter interactions according to the demands. However, due to their inherent physical properties, topological transitions (flat bands) exist only in the orthogonal directions,

Percolation transition in a topological phase
Physical Review B, 2023 Transition out of a topological phase is typically characterized by discontinuous changes in topological invariants along with bulk gap closings. However, as a clean system is geometrically punctured, it is natural to ask the fate of an underlying topological phase. To understand this physics we introduce and study both short and long-ranged toy models

Rotation controlled topological edge states in a trimer chain composed of meta-atoms
New Journal of Physics, 2022 Recently, topological chains have attracted extensive attention because of their simple structure, rich physics and important applications. In this work, we theoretically and experimentally uncover that the abundant topological phases of periodic trimer ...

Generalized topological transition matrix [PDF]
Topological Methods in Nonlinear Analysis, 2016 This article represents a major step in the unification of the theory of algebraic, topological and singular transition matrices by introducing a definition which is a generalization that encompasses all of the previous three. When this more general transition matrix satisfies the additional requirement that it covers flow-defined Conley-index ...

Abnormal Wave Propagation in Tilted Linear‐Crossing Metamaterials
Advanced Photonics Research, 2021 The propagation properties of electromagnetic waves depend on media dispersion in momentum space, which can be characterized using isofrequency contours (IFCs).
