Subspace Diagonalization on Quantum Computers using Eigenvector Continuation
Akhil Francis, Anjali A. Agrawal, Jack H. Howard +2
Quantum subspace diagonalization (QSD) methods are quantum-classical hybrid methods, commonly used to find ground and excited state energies by projecting the Hamiltonian to a smal…
Measuring NISQ Gate-Based Qubit Stability Using a 1+1 Field Theory and Cycle Benchmarking
Kubra Yeter-Aydeniz, Zachary Parks, Aadithya Nair +5
Some of the most problematic issues that limit the implementation of applications on Noisy Intermediate Scale Quantum (NISQ) machines are the adverse impacts of both incoherent and…
Flatband-Induced Itinerant Ferromagnetism in RbCoSe
Jianwei Huang, Zhicai Wang, Hongsheng Pang +8
CoSe (=K,Rb,Cs) is a homologue of the iron-based superconductor, FeSe. From a comprehensive study of RbCoSe via measurements of magnetization, tran…
Establishing non-thermal regimes in pump-probe electron-relaxation dynamics
MengXing Na, Fabio Boschini, Arthur K. Mills +8
Time- and angle-resolved photoemission spectroscopy (TR-ARPES) accesses the electronic structure of solids under optical excitation, and is a powerful technique for studying the co…
Quantum computation of magnon spectra
Akhil Francis, J. K. Freericks, A. F. Kemper
We demonstrate quantum computation of two-point correlation functions for a Heisenberg spin chain. Using the IBM Q 20 quantum machines, we find that for two sites the correlation f…
Observation of Chiral Surface Excitons in a Topological Insulator BiSe
H. -H. Kung, A. P. Goyal, D. L. Maslov +5
The protected electron states at the boundaries or on the surfaces of topological insulators (TIs) have been the subject of intense theoretical and experimental investigations. Suc…
