A New Experimental Method for Determining the Pinning Energy of an Abrikosov Vortex
We demonstrate a novel method of experimentally addressing the pinning energy of an Abrikosov vortex in high-temperature superconducting thin films. The method is based on our previously published theoretical framework considering the optimization of heterostructural bilayer films. To demonstrate our method, we have estimated the pinning energy of a typical BaZrO$_3$-nanocolumn within YBa$_2$Cu$_3$O$_{6+x}$ lattice using the experimental data from our previous study. Our calculations result in …

Short close-up video of a small, but intensely flowing waterfall in a canyon, filmed directly from the narrow path going next to it. Turquoise water, spray, the camera initially following the flow, then panning upwards to show the depth of the canyon...

I rarely leave my neighborhood these days, so when the opportunity came last weekend to visit a town about 80 km from my home, I took a little detour to visit and take photos of the town’s only national historical marker.
(Those who have been following me long enough know that documenting historical markers in #Wikidata and

Cast iron historical marker with the following white text on black: Pagdaong sa Nasugbu Sa pook na ito dumaong ang mga sundalo ng Unang Batalyon at 188th Glider Infantry ng 11th Airborne Division sa pangunguna ni Lt. General Robert Eichelberger, 31 Enero 1945. Nagsilbing kabalikat ng hukbong Amerikano ang mga gerilyang Filipino na pinangunahan ni Tenyente Koronel Marcelo Castillo at Koronel Eleuterio L. Adevoso.
Historical marker mounted vertically on a concrete pedestal with a few steps before it and surrounded by a low concrete wall.

Flying choir boy vibes tbh #BloomScrolling #CaliforniaNatives #SanFranciscoHellscape

Close up photo of a Romneya coulteri blossom looking like a choir boy who’s about to take flight. The flower is large, floppy, and has 3 or 4 large white petals, with an orange yellow fuzzy ball in the centre that looks like the choir boy’s head. Behind the flower many other Romneya stalks are visible, many with unopened flower buds and/or opened blossoms on them.

Atomic-scale mapping of interfacial phonon modes in epitaxial YBa2Cu3O7-δ / (La,Sr)(Al,Ta)O3 thin films: The role of surface phonons
We investigate the behavior of phonons at the epitaxial interface between YBa2Cu3O7-δ thin film and (La,Sr)(Al,Ta)O3 substrate using vibrational electron energy loss spectroscopy. Interfacial phonon modes with different degrees of scattering localization were identified. We find evidence that surface contributions from the surrounding environment can impose additional scattering modulation into local EELS measurements at the interface. A method to remove those contributions is then used to iso…
