Summary
We theoretically show that superconducting stripes influence nonlinear resistivity in crystals. A universal angular dependence of resistivity is predicted, aiding the detection of these stripes in cuprate superconductors above their transition temperature.
Area of Science:
- Condensed Matter Physics
- Materials Science
Background:
- Superconducting stripes are theorized to exist in cuprate superconductors.
- Understanding their impact on electronic properties is crucial.
Purpose of the Study:
- To theoretically investigate the influence of stripelike superconducting inclusions on nonlinear resistivity.
- To predict a measurable effect that can experimentally verify the presence of superconducting stripes.
Main Methods:
- Theoretical modeling of nonlinear resistivity in single crystals with stripelike superconducting inclusions.
- Analysis of the angular dependence of resistivity considering twinned stripe orientations.
Main Results:
- A universal dependence of nonlinear resistivity on the angle between applied current and crystal axes is predicted.
- This dependence holds even when stripe orientations vary due to twinning.
Conclusions:
- The predicted universal angular dependence provides a testable hypothesis for the existence of superconducting stripes.
- This research offers a new method to detect superconducting stripes in cuprate materials at and above their critical temperature.

01:24Superconductor
A substance that reaches superconductivity, a state in which magnetic fields cannot penetrate, and there is no electrical resistance, is referred to as a superconductor. In 1911, Heike Kamerlingh Onnes of Leiden University, a Dutch physicist, observed a relation between the temperature and the resistance of the element mercury. The mercury sample was then cooled in liquid helium to study the linear dependence of resistance on temperature. It was observed that, as the temperature decreased, the...
01:28Types Of Superconductors
A superconductor is a substance that offers zero resistance to the electric current when it drops below a critical temperature. Zero resistance is not the only interesting phenomenon as materials reach their transition temperatures. A second effect is the exclusion of magnetic fields. This is known as the Meissner effect. A light, permanent magnet placed over a superconducting sample will levitate in a stable position above the superconductor. High-speed trains that levitate on strong...
01:30The Hall Effect
Edwin H. Hall, in the year 1879, devised an experiment that could be used to identify the polarity of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.
01:12Double Resonance Techniques: Overview
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

01:26Linear Approximation in Frequency Domain
Linear systems are characterized by two main properties: superposition and homogeneity. Superposition allows the response to multiple inputs to be the sum of the responses to each individual input. Homogeneity ensures that scaling an input by a scalar results in the response being scaled by the same scalar.
In contrast, nonlinear systems do not inherently possess these properties. However, for small deviations around an operating point, a nonlinear system can often be approximated as linear.

01:22Resistivity
When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:
