Fig. 4: Magnetic field dependence of Fano interference in La2-xSrxCuO4.
From: Fano interference between collective modes in cuprate high-Tc superconductors
a, c Temperature dependence of I3ω with a magnetic field applied along the c-axis of a x ~0.16 (OP43), c x ~0.30 (OD30). b, d Corresponding temperature dependence of Φ3ω from the two samples. The peak terahertz driving field strength used for these measurements is ~25 kV/cm. The anti-resonance becomes increasingly broadened by the magnetic field, indicating a broadening/softening of the coupled mode with a magnetic field.
