Weighted Berry curvature and global geometry of mixed quantum states
Dominik Kuczyński, Erik Sjöqvist
We examine the geometric interpretation of the quantum geometric tensor proposed in [Phys. Rev. B {\bf 110}, 035404 (2024)] for mixed quantum states, focusing on its imaginary part…
-pod realization of nonadiabatic holonomic quantum computation
Oskar Axelsson, Claes Fälth, Elias Henriksson Lindberg +1
Holonomic quantum computation (HQC) realizes quantum gates through non-Abelian geometric phases, providing an experimentally accessible approach to quantum control. While the nonad…
Quasi-holonomy in non-adiabatic quantum evolution
Erik Sjöqvist, Adam Fredriksson
We develop a framework for quasi-holonomy in non-adiabatic quantum time evolution of subspaces along loops in a complex Grassmannian. By factoring the Schrödinger evolution into dy…
Quantum spin systems: toroidal classification and geometric duality
Vahid Azimi-Mousolou, Anders Bergman, Anna Delin +4
Toroidal classification and geometric duality in quantum spin systems is presented. Through our classification and duality, we reveal that various bipartite quantum features in mag…
Quantum analog of Landau-Lifshitz-Gilbert dynamics
Yuefei Liu, Ivan P. Miranda, Lee Johnson +7
The Landau-Lifshitz-Gilbert (LLG) and Landau-Lifshitz (LL) equations play an essential role for describing the dynamics of magnetization in solids. While a quantum analog of the LL…
Coupled spin-lattice dynamics from the tight-binding electronic structure
Ramon Cardias, Simon Streib, Zhiwei Lu +7
We developed a method which performs the coupled adiabatic spin and lattice dynamics based on the tight-binding electronic structure model, where the intrinsic magnetic field and i…
