Web1 de ago. de 2024 · In Section 3, we first briefly review the basics of GPR and then present the hidden physics model for the elastic wave equations to estimate the P-wave and S-wave velocities, density. In Section 4, several numerical examples are provided to demonstrate the effectiveness of the method. Finally, we conclude in Section 5. WebThe synthetic gauge field and dissipation are of crucial importance in both fundamental physics and applications. Here, we investigate the interplay of the uniform flux and the on-site gain and loss by considering a dissipative two-leg ladder model. By calculating the spectral winding number and the generalized Brillouin zone, we predict the non …
