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…
Polaronic hybridization of atoms, dimers and trimers in a Bose-Einstein condensate
Carsten Robens, Arthur Christianen, Alexander Y. Chuang +4
The Bose polaron problem of an impurity immersed in a Bose-Einstein condensate (BEC) has been predicted to feature strong correlations arising from bound states of multiple bosons…
Quantum Contact Processes on a Topological Lattice
Julius Bohm, Richard Schmidt, Michael Fleischhauer +1
Contact processes play an important role in classical non-equilibrium dynamics, describing the spreading of diseases, the dynamics of earthquakes and forest fires, and the distribu…
Enhancing superconductivity using thermal bosons
Ekaterina Vlasiuk, Manfred Salmhofer, Eugene Demler +1
We investigate how the strong coupling of a superconductor to thermal bosons can enhance its superconducting critical temperature. To tackle this problem, we use a renormalization…
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…
