Sažetak
In this talk I will present insights into some of the important aspects of cuprate physics gained from measurements of nonlinear response to external fields. The experiments are made possible by a specially developed probe, which eliminates sample heating problems by using rapidly alternating (radio-frequency) fields and detecting the sample response at harmonics of the excitation frequency. Although not a conventional method, nonlinear response can provide a wealth of information on electronic physics, and the conditions necessary for the occurrence of nonlinearities will be expounded. These include strongly nonlinear response close to the superconducting transition temperature of several cuprates, collective dynamics of charge order, and unconventional charge stripe precursor phases. Also, some components of the nonlinear signal can be connected to broken symmetries in the sample – this will be discussed in the context of nematic order and pseudogap.
