Lattice Bose polarons at strong coupling and quantum criticality
Ragheed Alhyder, Victor E. Colussi, Matija Čufar +3
We develop a new theoretical framework for exploring a mobile impurity interacting strongly with a highly correlated bath of bosons in the quantum critical regime of a Mott insulat…
Chiral polaron formation on the edge of topological quantum matter
Amit Vashisht, Ivan Amelio, Laurens Vanderstraeten +3
Immersing a mobile impurity in a quantum many-body environment can reveal fundamental properties of the background medium, hence providing a powerful probe of quantum matter. This…
Probing a quantum spin liquid with equilibrium and nonequilibrium hole dynamics
J. H. Nyhegn, K. Knakkergaard Nielsen, G. M. Bruun
The properties and experimental identification of quantum spin liquids (QSLs) remain an important topic with many fundamental questions. Here, we explore the dynamics of a single c…
Interactions mediated by atoms, photons, electrons, and excitons
Rosario Paredes, Georg Bruun, Arturo Camacho-Guardian
Interactions between quasiparticles mediated by a surrounding environment are ubiquitous and lead to a range of important effects from collective modes of low temperature quantum g…
Green's function approach to interacting lattice polaritons and optical nonlinearities in subwavelength arrays of quantum emitters
Simon Panyella Pedersen, Georg M. Bruun, Thomas Pohl
Sub-wavelength arrays of quantum emitters offer an efficient free-space approach to coherent light-matter interfacing, using ultracold atoms or two-dimensional solid-state quantum…
