Interlayer Fermi Polarons in Bilayer MoTe
Ruihao Ni, Eugen Dizer, Maximilian Wolf +15
Atomic bilayers of transition metal dichalcogenides (TMDs) host quantum phases governed by the layer degree of freedom, including bilayer Wigner crystals, fractional Chern insulato…
Anderson orthogonality scaling in the Rabi-driven heavy Fermi polaron
Michael Rautenberg, Tobias Krom, Eugen Dizer +6
The Anderson orthogonality catastrophe (AOC) is a paradigmatic many-body phenomenon in which a local perturbation induces a macroscopic response of a Fermi sea. We probe signatures…
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…
Tunable state-dependent interactions in collisionally stable mixtures of polar molecules
Hubert J. Jóźwiak, Hanwei Yang, Eugen Dizer +2
We propose encoding a pseudo-spin- system in the ground () and first excited () vibrational states of polar molecules. Double microwave shielding simultaneously shie…
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 -…
Microscopic Model of Exciton Polarons in 2D Wigner Crystals
Haydn S. Adlong, Eugen Dizer, Richard Schmidt +2
Monolayer transition-metal dichalcogenides (TMDs) provide a platform for realizing Wigner crystals and enable their detection via exciton spectroscopy. We develop a microscopic the…
Wigner polarons reveal Wigner crystal dynamics in a monolayer semiconductor
Lifu Zhang, Liuxin Gu, Haydn S. Adlong +12
Wigner crystals, lattices made purely of electrons, are a quintessential paradigm of studying correlation-driven quantum phase transitions. Despite decades of research, the interna…
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…
Spectral properties and observables in ultracold Fermi gases
Eugen Dizer, Jan Horak, Jan M. Pawlowski
We calculate non-perturbative self-consistent fermionic and bosonic spectral functions of ultra-cold Fermi gases with the spectral functional approach. This approach allows for a d…
Hadronic vacuum polarization correction to the bound-electron factor
Eugen Dizer, Zoltán Harman
The hadronic vacuum polarization correction to the factor of a bound electron is investigated theoretically. An effective hadronic Uehling potential obtained from measured cros…
Hadronic vacuum polarization correction to atomic energy levels
Sören Breidenbach, Eugen Dizer, Halil Cakir +1
The shift of atomic energy levels due to hadronic vacuum polarization is evaluated in a semiempirical way for hydrogenlike ions and for muonic hydrogen. A parametric hadronic polar…
