A soft-clamped topological waveguide for phonons
Xiang Xi, Ilia Chernobrovkin, Jan Košata +5
Topological insulators were originally discovered for electron waves in condensed matter systems. Recently this concept has been transferred to bosonic systems such as photons and…
Limit cycles as stationary states of an extended Harmonic Balance ansatz
Javier del Pino, Jan Košata, Oded Zilberberg
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 t…
Fixing the rotating-wave approximation for strongly-detuned quantum oscillators
Jan Košata, Anina Leuch, Tobias Kästli +1
Periodically-driven oscillators are commonly described in a frame co-rotating with the drive and using the rotating-wave approximation (RWA). This description, however, is known to…
Second-order topological modes in two-dimensional continuous media
Jan Košata, Oded Zilberberg
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…
Spin detection via parametric frequency conversion in a membrane resonator
J. Košata, O. Zilberberg, Christian L. Degen +2
Recent demonstrations of ultracoherent nanomechanical resonators introduce the prospect of new protocols for solid state sensing applications. Here, we propose to use two coupled u…
Magnetic resonance force microscopy with a one-dimensional resolution of 0.9 nanometers
U. Grob, M. D. Krass, M. Héritier +7
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…
