A delta angle, a term well known to civil engineers, is a measurement used in designing roadways. The delta angle is used to make other relevant calculations, or it can be determined using known measurements. Definition A delta angle is the measurement in degrees where two straight lines, als...
The signature delta wings needed a super aggressive angle to generate lift at low speeds, which forced the engineers to fit Concorde with its signature nose, which was lowered during takeoff and landing so the crew could see the runway. Jacek Krywko, Ars Technica, 29 Mar. 2024 The kit cons...
We use angle resolved photoemission spectroscopy to probe the electronic excitations of the non-superconducting state that exists between the antiferromagnetic Mott insulator at zero doping and the superconducting state at larger dopings in Bi_2Sr_2CaCu_2O_{8+\delta}. We find that this state is...
Angle-resolved photoemission experiments reveal evidence of an energy gap in the normal state excitation spectrum of the cuprate superconductor Bi2Sr2CaCu2O8+delta. This gap exists only in underdoped samples and closes around the doping level at which the superconducting transition temperature T-c is...
Reflections on the glasssurfaces everywhere on the 737NGX has amazing reflection and behavior with light that I haven’t seen before. It’s really neat to see as you’re panning around the windows outside, and the instruments inside, that the light really does play off the glass as though...

In this paper, we show that this phase, in conjunction with the Witten effect, gives rise to a topological phase proportional to the vacuum angle \theta and thereby connected with CP violation. We show that this phase becomes quantised in a vacuum state \delta _{\theta }=n\theta and ...
