Our results show that such a gyroscope may be also used for nanopositioning purposes in addition to its usual navigation application. Such a theory, called the Chameleon theory (presented in 2004 by Khoury and Weltman), is a dark matter model that is fundamentally dependent on the background density and involves mass coupling to the background field. B. infrared. We have seen no. Here, the signal strength decreased by, This leads to the conclusion that the origin of the effect is either connected to a critical low temperature independent, of the material used or that the effect is trigged by the cryogenic liquid helium itself. A hierarchy of scalar fields in the universe suggests a relationship with properties varying with background conditions or a hierarchy from the far background field to the local background field. An anomalous signal was found of similar value compared to our previous measurements with a changed sign. niobium tube. This paper will discuss the measurements recently obtained with the fiber optic gyroscopes. We recently implemented a magnetic encoder that we will use for future, The following data was obtained following a standardized speed profile which lasts about 210 seconds. The angular distribution of the shift in the UV suggests a large A quantum wave equation with logarithmic nonlinearity is known to describe such systems, at least in a leading-order approximation, wherein the nonlinear coupling is related to temperature. rotating superconductor experiments can be attributed to dark matter - like the formation of dark matter rings outside the confines of a galaxy. propulsion systems (space drive) using a radical new approach e.g. The pot is mechanically attached to the axis of a cryomotor (Phytron VSH-UHVC 100) allowing it to spin up to an, angular velocity of 60 rad/s. Comment: non technical review. Access scientific knowledge from anywhere. In superfluid helium, when an ion is flying through the liquid, it can create vortices in its wake. A superfluid acts as if it were a mixture of a normal component, with all the properties of a normal fluid, and a superfluid component. We are also planning to increase th. An inertial mass arising from quantum-mechanical interference is derived. The stepper motor is also producing acoustic noise in higher, frequency bands, however, here it makes no difference if the motor is working at low or normal temperatures and, therefore such influence can be easily assessed in room temperature calibration measurements. The other is a search for an external gauge field associated with the He II order parameter. We previously reported anomalous fiber‐optic gyroscope signals observed above rotating rings at temperatures close to liquid helium. The superfluid current is generated by steadily rotating the sphere about a vertical axis while cooling through the lambda-point and then stopping the sphere's rotation at a lower temperature. 2A, we show several snapshots in a 2.08 × 0.4-mm subregion of our measurement area, with the tracer particles used for further analysis indicated. assumed for the algebraic function f(T) and solutions are obtained. An array of vortices, each of strength rc = h/ m, core radius a and nearly parallel to Z, forms a schematic model of rotating liquid helium II. Our measurements of {ital S} and {Delta}{nu} enable us to quote a value of {ital m}{prime}/2{ital m}{sub {ital e}} for niobium of 1.000 084 (21). We constructed a new cryostat experiment that allows rotating a large quantity of liquid helium together with a superconducting niobium tube. Due to wrong natural philosophy scientists scratch only surface of hurricane and The model predicts that the temperature difference creates a direction in space in which quantum liquids can flow, even against the force of gravity. “Interferometric Closed-Loop Fiber Optic Gyrocopes with Linear Output,” Proceedings of the the 5th, itomagnetic Fields in Rotating Superconductors and, “Experimental Detection of the Gravitomagnetic London Mom, evich, I., “Investigation of Frame-Dragging-Like Signals f, T., “Precise Determination of the Cooper-Pair Mass,”, T., “Determination of the Cooper-Pair Mass in Niobium,”.

Figure 3b shows the gyro measurement at the center position (1) when the pot was rotating, with angular velocities up to 60 rad/s. Quantized vortices are central to the behavior of two-dimensional superfluids, as recognized by the 2016 Nobel Prize in Physics. However, this signal is already very close to our. Recent developments in this new subject are summarized by many of the researchers most directly involved. The main part of our experiment is a rotating pot as shown in Figure 1 inside. general solution is, These relics from the early universe could be the answer to many astrophysical conundrums. This paper emphasizes certain little known aspects of Einstein's general theory of relativity. In their experiments, Autti and colleagues rotated a helium-3-filled nafen sample around an axis parallel to the strands in the aerogel . clockwise and counter-clockwise rotation yielded different results.
