I want to simulate Superconducting Qubits With Al Trilayer Josephson Junctions
Mulya Hermana
Create a new model in Comsol and select the "Electromagnetic Waves, Time-Harmonic" physics interface. Define the geometry of the junction, including the superconducting electrodes and the insulating layer in between. Define the material properties of the superconductors and insulator, such as their conductivity, permittivity, and magnetic permeability. Define the initial conditions and boundary conditions for the system. For example, you may specify that the superconductors are in a superconducting state and that there is no current flowing across the insulating layer at the start of the simulation. Set up the equations that describe the behavior of the junction, including the Josephson equations and the London equations for superconductivity. Solve the system of equations to obtain the electromagnetic fields and currents in the junction over time. Analyze the results to study the behavior of the junction, such as the current-voltage characteristics, and the time-evolution of the superconducting phases.
To simulate a Josephson junction in Comsol, you need to set up a mathematical model that describes the behavior of the junction and its interactions with the surrounding environment. Here are the general steps to simulate a Josephson junction in Comsol:
It is important to note that simulating a Josephson junction can be a complex task, and it may be necessary to include additional physics and coupled equations, such as heat transfer, in order to accurately capture the behavior of the junction.
