An investigation on the recurrent function of the Pythagorean fuzzy cellular topological dynamical system [PDF]
HeliyonThis study is about Pythagorean fuzzy cellular topological dynamical system which is generated using Pythagorean fuzzy cellular space. A dynamical system receives input for a certain function and performs an iterative procedure for that same function.

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.

IEEE Transactions on Power Systems, 2023 The topology transition problem of transmission networks is becoming increasingly crucial with topological flexibility more widely leveraged to promote high renewable penetration. This paper proposes a novel methodology to address this problem. Aiming at achieving a bumpless topology transition regarding both static and dynamic performance, this ...

IEEE Transactions on Power Systems, 2022 Network topology has significant impacts on operational performance of power systems. While extensive research efforts have been devoted to optimization of network topology for improving various system performances, the problem of how to transition from the initial topology to the desired optimal topology requires study.

Topological Transitions in Metamaterials [PDF]
Science, 2012 Manipulating Optical TopologyPhase transitions in solid-state systems are often associated with a drastic change in the properties of that system. For example, metal-to-insulator transition or magnetic-to-nonmagnetic states find wide application in memory storage technology.

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 ...
