Slow-phonon control of spin Edelstein effect in Rashba -wave altermagnets
Mohsen Yarmohammadi, Jacob Linder, James K. Freericks
Altermagnets have zero net magnetization yet feature spin-split bands. Here, we investigate how slow lattice vibrations (phonons) influence both the intrinsic and externally induce…
Low Depth Unitary Coupled Cluster Algorithm for Large Chemical Systems
Jeremy Canfield, Dominika Zgid, J K Freericks
The unitary coupled cluster (UCC) algorithm is one of the most promising implementations of the variational quantum eigensolver for quantum computers. However, for large systems, t…
Hidden rotation symmetry of the Jordan-Wigner transformation and its application to measurement in quantum computation
Grant Davis, James K. Freericks
Using a global rotation by theta about the z-axis in the spin sector of the Jordan-Wigner transformation rotates Pauli matrices X and Y in the x-y-plane, while it adds a global com…
Classical reservoir approach for efficient molecular ground state preparation
Zekun He, Dominika Zgid, A. F. Kemper +1
Ground state preparation is a central application of quantum algorithms for electronic structure. We introduce the classical reservoir approach, a low cost variational ansatz tailo…
Cavity-induced coherent magnetization and polaritons in altermagnets
Mohsen Yarmohammadi, Libor Å mejkal, James K. Freericks
Altermagnets feature antiparallel spin sublattices with -, -, or -wave spin order, yielding nonrelativistic spin splitting without net magnetization. We show that embeddin…
Probing Bound State Relaxation Dynamics in Systems Out-of-Equilibrium on Quantum Computers
Heba A. Labib, Goksu Can Toga, J. K. Freericks +1
Pump-probe spectroscopy is a powerful tool for probing response dynamics of quantum many-body systems in and out-of-equilibrium. Quantum computers have proved useful in simulating…
