Nonlinear Stability of Large-Period Traveling Waves Bifurcating from the Heteroclinic Loop in the FitzHugh-Nagumo Equation

Kavli Affiliate: Ke Wang | First 5 Authors: Ji Li, Ke Wang, Qiliang Wu, Qing Yu, | Summary: A wave front and a wave back that spontaneously connect two hyperbolic equilibria, known as a heteroclinic wave loop, give rise to periodic waves with arbitrarily large spatial periods through the heteroclinic bifurcation. The nonlinear stability of […]

Exponential quantum speedups in quantum chemistry with linear depth

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state inputs, […]
