Engineering SU()-Symmetric Hubbard Models with Microwave-Shielded Dipolar Molecules

Jing-Lun Li, Ragheed Alhyder, Andreas Schindewolf +3

The paper proposes a method to realize SU(N)-symmetric extended Hubbard models with ultracold polar molecules by using microwave shielding to tune on-site and off-site interactions…

Scale invariance of the polaron energy at the Mott-superfluid critical point

Matija Čufar, Ragheed Alhyder, C. J. Bradly +4

Continuous quantum phase transitions are characterized by an order parameter and correlation functions that are often challenging to access experimentally or in direct numerical si…

Phenomenological model of decaying Bose polarons

Ragheed Alhyder, Georg M. Bruun, Thomas Pohl +2

Cold atom experiments show that a mobile impurity particle immersed in a Bose-Einstein condensate forms a well-defined quasiparticle (Bose polaron) for weak to moderate impurity-bo…

Fluctuation-Induced Supersolidity at the Superfluid-Solid Interface

Baptiste Coquinot, Ragheed Alhyder, Alberto Cappellaro +1

Supersolidity, combining superfluid and crystalline orders, has been realized in dipolar Bose-Einstein condensates by tuning interatomic interactions. Here we show that supersolidi…

Tunable Field-Linked -wave Interactions in Dipolar Fermi Mixtures

Jing-Lun Li, Georgios M. Koutentakis, Mateja Hrast +3

Spin mixtures of degenerate fermions are a cornerstone of quantum many-body physics, enabling superfluidity, polarons, and rich spin dynamics through -wave scattering resonances…

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…
