Quantization of integrable and chaotic three-particle Fermi-Pasta-Ulam-Tsingou models
Alio Issoufou Arzika, Andrea Solfanelli, Harald Schmid +1
We study the transition from integrability to chaos for the three-particle Fermi-Pasta-Ulam- Tsingou (FPUT) model. We can show that both the quartic b-FPUT model ( = 0) and the…
Quantum Yu-Shiba-Rusinov dimers
Harald Schmid, Jacob F. Steiner, Katharina J. Franke +1
Magnetic adatoms on a superconducting substrate undergo a quantum phase transition as their exchange coupling to the conduction electrons increases. For quantum spins, this transit…
Tricritical point in the quantum Hamiltonian mean-field model
Harald Schmid, Johannes Dieplinger, Andrea Solfanelli +2
Engineering long-range interactions in experimental platforms has been achieved with great success in a large variety of quantum systems in recent years. Inspired by this progress,…
Nonlinearity accelerates the thermalization of the quartic FPUT model with stochastic baths
Harald Schmid, Sauro Succi, Stefano Ruffo
We investigate the equilibration process of the strongly coupled quartic Fermi-Pasta-Ulam-Tsingou (FPUT) model by adding Langevin baths to the ends of the chain. The time evolution…
