Comment on "Absence of Off-Diagonal Long- Range Order in hcp He Dislocation Cores"
M. Boninsegni, A. Kuklov, L. Pollet +2
We contend that the arguments provided in Phys. Rev. Lett. 130, 016001 (2023), purporting to show the absence of off-diagonal long-range order in hcp He dislocation cores are m…
Bipolaronic superconductivity out of a Coulomb gas
J. Sous, C. Zhang, M. Berciu +4
Employing unbiased sign-problem-free quantum Monte Carlo, we investigate the effects of long-range Coulomb forces on BEC of bipolarons using a model of bond phonon-modulated electr…
Bipolaronic high-temperature superconductivity
C. Zhang, J. Sous, D. R. Reichman +4
Electron-lattice interactions play a prominent role in quantum materials, making a deeper understanding of direct routes to phonon-mediated high-transition-temperature ($T_{\mathrm…
Real-frequency response functions at finite temperature
I. S. Tupitsyn, A. M. Tsvelik, R. M. Konik +1
Building on previous developments, we show that the Diagrammatic Monte Carlo technique allows to compute finite temperature response functions directly on the real-frequency axis w…
Signatures of multiple charge excitations in RIXS spectra of metals
I. S. Tupitsyn, A. M. Tsvelik, R. M. Konik +1
We study how multiple charge excitations appear in the resonant inelastic x-ray scattering (RIXS) spectra of metals. The single excitations in the problem are the plasmons and elec…
Resonant Inelastic X-Ray Scattering in Metals: A Diagrammatic Approach
A. M. Tsvelik, R. M. Konik, N. V. Prokof'ev +1
We develop a formalism to study the Resonant Inelastic X-ray Scattering (RIXS) response in metals based on the diagrammatic expansion for its cross section. The standard approach t…
