Sideband attraction via internal resonance in a multimode membrane as a mechanism for frequency combs Open
We explore self-induced parametric coupling between a driven (low frequency) and an undriven (high frequency) mode, also called internal resonances, in a membrane micromechanical system. Specifically, we focus on the formation of a limit c…

Limit cycles as stationary states of an extended harmonic balance ansatz Open
A limit cycle is a self-sustained, periodic, isolated motion appearing in autonomous differential equations. As the period of a limit cycle is unknown, finding it as a stationary state of a rotating ansatz is challenging. Correspondingly, …
Limit cycles as stationary states of an extended Harmonic Balance ansatz Open
A limit cycle is a self-sustained periodic motion appearing in autonomous ordinary differential equations. As the period of the limit cycle is a-priori unknown, it is challenging to find them as stationary states of a rotating ansatz. Corr…
Fixing the rotating-wave approximation for strongly detuned quantum oscillators Open
Periodically driven oscillators are commonly described in a frame corotating with the drive and using the rotating-wave approximation (RWA). This description, however, is known to induce errors for off-resonant driving. Here, we show that …
Codebase release 0.5 for HarmonicBalance.jl Open
HarmonicBalance.jl is a publicly available Julia package designed to simplify and solve systems of periodic time-dependent nonlinear ordinary differential equations. Time dependence of the system parameters is treated with the harmonic bal…

Second-order topological modes in two-dimensional continuous media Open
We present a symmetry-based scheme to create zero-dimensional (0D) second-order topological modes in continuous two-dimensional (2D) systems. We show that a metamaterial with a p6m-symmetric pattern exhibits two Dirac cones, which can be g…
Second-order topological modes in 2D continuous media Open
We present a symmetry-based scheme to create 0D second-order topological modes in continuous 2D systems. We show that a metamaterial with a \textit{p6m}-symmetric pattern exhibits two Dirac cones, which can be gapped in two distinct ways b…

Magnetic Resonance Force Microscopy with a One-Dimensional Resolution of 0.9 Nanometers Open
Magnetic resonance force microscopy (MRFM) is a scanning probe technique capable of detecting MRI signals from nanoscale sample volumes, providing a paradigm-changing potential for structural biology and medical research. Thus far, however…
Stability of Hydrogen Hydrates from Second-Order Møller–Plesset Perturbation Theory Open
The formation of gas hydrates and clathrates critically depends on the interaction between the host water network and the guest gas species. Density functional calculations can struggle to quantitatively capture these dispersion-type inter…
Polarisation analysis on the LET time-of-flight spectrometer Open
We present a design for implementing uniaxial polarisation analysis on the LET cold neutron time-of-flight spectrometer, installed on the second target station at ISIS. The polarised neutron beam is to be produced by a transmission-based s…
