Fig. 2: The results for observing interaction-induced Zitterbewegung of doublons in electric circuits.
From: Observation of interaction-induced phenomena of relativistic quantum mechanics
a The red, blue, and green lines correspond to simulated results of the center mass (〈n〉) for the input voltage-packet as a function of time with \(C_{{{{{{{{\mathrm{U}}}}}}}}\prime }\) = 11, 12 and 13 nF, respectively. b The left chart plots the photograph image of the fabricated circuit, and the corresponding enlarged view is presented in right charts. The red, blue, and green circles enclose the grounding capacitor CU, \(C_{{{{{{{{\mathrm{U}}}}}}}}\prime }\) on the main and first lateral diagonals and grounding inductor Lg, respectively. The value of C, CU, and Lg are taken as 1, 15 nF and 3.3 μH, respectively. c The measured results of the center mass in the time domain are presented by red, blue and green lines with \(C_{{{{{{{{\mathrm{U}}}}}}}}\prime }\) = 11, 12 and 13 nF, respectively.
