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 Šmejkal, James K. Freericks
Altermagnets feature antiparallel spin sublattices with -, -, or -wave spin order, yielding nonrelativistic spin splitting without net magnetization. We show that embeddin…
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…
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…
Cavity-assisted magnetization switching in a quantum spin-phonon chain
Mohsen Yarmohammadi, Peter M. Oppeneer, James K. Freericks
We propose a Néel magnetization switching mechanism in a hybrid magnon-phonon optical cavity system. A terahertz-pumped single-mode cavity photon couples to a spin-phonon chain, wh…
