Augmenting Imaginary-Time Evolution with Local Geometric Information
Carlos L. Benavides-Riveros, Prachi Sharma, Fedor Šimkovic +1
Imaginary-time evolution (ITE) underpins a broad family of algorithms for ground-state preparation in quantum simulation and quantum many-body physics. In these methods, convergenc…
Quantum subspace expansion in the presence of hardware noise
João C. Getelina, Prachi Sharma, Thomas Iadecola +2
Finding ground state energies on current quantum processing units (QPUs) using algorithms like the variational quantum eigensolver (VQE) continues to pose challenges. Hardware nois…
Optical conductivity and damping of plasmons due to electron-electron interaction
Prachi Sharma, Alessandro Principi, Giovanni Vignale +1
We re-visit the issue of plasmon damping due to electron-electron interaction. The plasmon linewidth can related to the imaginary part of the charge susceptibility or, equivalently…
Optical conductivity of a metal near an Ising-nematic quantum critical point
Songci Li, Prachi Sharma, Alex Levchenko +1
We study the optical conductivity of a pristine two-dimensional electron system near an Ising-nematic quantum critical point. We discuss the relation between the frequency scaling…
