Full-frequency GW without frequency [PDF]
The Journal of Chemical Physics, 2021 Efficient computer implementations of the GW approximation must approximate a numerically challenging frequency integral; the integral can be performed analytically, but doing so leads to an expensive implementation whose computational cost scales as O(N6), where N is the size of the system. Here, we introduce a new formulation of the full-frequency GW

Simulation of TiN/HfO2/Pt memristor I–V curve for different conductive filament thickness [PDF]
Modern Electronic Materials, 2021 The operation of the TiN/HfO2/Pt bipolar memristor has been simulated by the finite elements method using the Maxwell steady state equations as a mathematical basis.

A continuum of bright and dark-pulse states in a photonic-crystal resonator
Nature Communications, 2022 A Kerr-nonlinear resonator with normal dispersion supports bright and dark pulse states. With photonic crystal ring resonators, this work demonstrates a continuum across these nonlinear states and explores the underlying mechanism.

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2016 We study the dynamics of coupled phase oscillators on a two-dimensional Kuramoto lattice with periodic boundary conditions. For coupling strengths just below the transition to global phase-locking, we find localized spatiotemporal patterns that we call “frequency spirals.” These patterns cannot be seen under time averaging; they become visible only ...

A Dual-Band Dual-Polarized Base Station Antenna Array With Isolation Enhancement
IEEE Open Journal of Antennas and Propagation, 2023 In this paper, a dual-band dual-polarized antenna with isolation enhancement is designed. The proposed antenna operates in the frequency range of 3.4–3.6 GHz and 4.8-5 GHz, where the center frequency of the high band (HB) is 1.4 times that of the ...

, 2023 Given an infinite word with values in a finite alphabet that admit frequencies for all its factors, the smallest frequency function associates with a given positive integer the smallest frequency for factors of this length, and the recurrence function measures the gaps between successive occurrences of factors.
