Dynamically reconfigurable topological routing in nonlinear photonic systems
The propagation path of topologically protected states is bound to the interface between regions with different topology, and as such, the functionality of linear photonic devices leveraging these states is fixed during fabrication. Here, we propose a mechanism for dynamic control over a driven dissipative system's local topology, yielding reconfigurable topological interfaces and thus tunable paths for protected routing. We illustrate our approach in non-resonantly pumped polariton lattices, w…

Just wrote this quickie shell script to create and launch Debian13 KVM VMs. Just provide the hostname. Sharing in case someone else can use this.
The template is the debian13 nocloud image that I expanded to 20 GB. https://cloud.debian.org/images/cloud/trixi…

Tunable magnon-phonon cavity via structural phase transition
Strong coupling between two quantized excitations in a cavity has the potential to lead to hybridized states that bestow novel quantum phenomena as required for emerging applications. In particular, tunable hybrid magnon-phonon cavities with precise control knobs are in pressing demand for developing quantum functionalities in solid-state platforms. Here, using a combination of synthesis and characterization tools, we present an epitaxial La0.7Sr0.3MnO3/SrTiO3 (LSMO/STO) heterostructure that ma…

Kirby Tilt 'n' Tumble was released in Japan 25 years ago today (August 23, 2000). One of the coolest, most unique Game Boy Color games to come out-- it's a real blast. Here's my copy, and also a Japanese ad for it.

Gate-tunable Josephson parametric amplifiers based on semiconductor nanowires
Superconductor-semiconductor hybrid materials have been extensively used for experiments on electrically tunable quantum devices. Notably, Josephson junctions utilizing nanowire weak links have enabled a number of new gate-tunable qubits, including gatemons, Andreev level qubits and spin qubits. Conversely, superconducting parametric amplifiers based on Josephson junctions have not yet been implemented using nanowires, even though such nearly quantum limited amplifiers are key elements in exper…

Yes, someone was indeed dumb enough to tell a man so unafraid of death that he was willing to go into the void on a fragile explosive rocket, a coward.

The Grateful Dead is this afternoon's background, from 1979, which is a pleasant tumbling sort of thing.
The vocals are terrible of course but that hardly matters.

Narrow-linewidth, piezoelectrically tunable photonic integrated blue laser
Frequency-agile lasers operating in the ultraviolet-to-blue spectral range (360-480 nm) are critical enablers for a wide range of technologies, including free-space and underwater optical communications, optical atomic clocks, and Rydberg-atom-based quantum computing platforms. Integrated photonic lasers offer a compelling platform for these applications by combining low-noise performance with fast frequency tuning in a compact, robust form factor through monolithic integration. However, realiz…
