Superconductivity in the presence of strong electron-phonon interactions and frustrated charge order
Zi-Xiang Li, Marvin L. Cohen, Dung-Hai Lee
We study the superconductivity of strongly coupled electron-phonon systems where the geometry of the lattice frustrates the charge order by the sign-problem-free Quantum Monte Carl…
Electronic and phononic properties of a two dimensional electron gas coupled to dipolar phonons via small-momentum-transfer scattering
Zi-Xiang Li, T. P. Devereaux, Dung-Hai Lee
We study the electron and phonon spectral functions as well as superconductivity for a two dimensional electron gas couped to dipolar phonons via small-momentum transfer scattering…
Does the existence of Majorana zero mode in superconducting vortices imply the superconductivity is topologically non-trivial?
Lokman Tsui, Zi-Xiang Li, Yen-Ta Huang +2
We show that the presence of Majorana zero modes (2D), and chiral-dispersing Majorana modes (3D), in the vortex cores of superconductors are neither sufficient nor necessary condit…
Sign-Problem-Free Fermionic Quantum Monte Carlo: Developments and Applications
Zi-Xiang Li, Hong Yao
Reliable simulations of correlated quantum systems, including high-temperature superconductors and frustrated magnets, are increasingly desired nowadays to further understanding of…
