Mass-gap functional determinant approach for mobile Fermi polarons
Emilio Ramos Rodríguez, Eugen Dizer, Xin Chen +1
We extend the functional determinant approach (FDA), previously restricted to static impurities, to the case of finite-mass impurities by using the mass-gap description of Fermi po…
Emergent Fermi polarons in Dirac materials
Xin Chen, Eugen Dizer, Rafał Ołdziejewski +3
We investigate band-structure effects on the absorption spectra of quantum impurities in Dirac materials. We uncover the formation of novel quasiparticles -- Dirac-Fermi polarons -…
Interband optical conductivities in two-dimensional tilted Dirac bands revisited within the tight-binding model
Chao-Yang Tan, Jian-Tong Hou, Xin Chen +6
Within the framework of linear response theory, we theoretically investigated the interband longitudinal optical conductivities (LOCs) in two-dimensional (2D) tilted Dirac bands us…
Mass-gap description of heavy impurities in Fermi gases
Xin Chen, Eugen Dizer, Emilio Ramos Rodríguez +1
We present a unified theory that connects the quasiparticle picture of Fermi polarons for mobile impurities to the Anderson orthogonality catastrophe for static impurities. By oper…
Possible High temperature Superconductivity above 200K mediated by Bose Einstein Condensation of exciton
Shisheng Lin, Shaoqi Huang, Minhui Yang +3
Exciton mediated superconductor is a fascinating quantum phase of matter that occurs when excitons become the dominant excitation in materials, which is also very promising for hig…
Superconductivity induced by strong electron-exciton coupling in doped atomically thin semiconductor heterostructures
Jonas von Milczewski, Xin Chen, Atac Imamoglu +1
We study a mechanism to induce superconductivity in atomically thin semiconductors where excitons mediate an effective attraction between electrons. Our model includes interaction…
