The toric code under antiferromagnetic isotropic Heisenberg interactions
Won Jang, Robert Peters, Thore Posske
We investigate the impact of an isotropic antiferromagnetic Heisenberg perturbation on the toric code, focusing on the resulting quantum phase transition and the nature of the phas…

Hinge non-Hermitian skin effect in the single-particle properties of a strongly correlated f-electron system
Robert Peters, Tsuneya Yoshida
Non-Hermitian systems exhibit novel phenomena without Hermitian counterparts, such as exceptional points and the non-Hermitian skin effect. These non-Hermitian topological phenomen…

Quantum skyrmion dynamics studied by neural network quantum states
Ashish Joshi, Robert Peters, Thore Posske
We study the dynamics of quantum skyrmions under a magnetic field gradient using neural network quantum states. First, we obtain a quantum skyrmion lattice ground state using varia…
