Parton theory of magnetic polarons: Mesonic resonances and signatures in dynamics
Fabian Grusdt, Marton Kanasz-Nagy, Annabelle Bohrdt +5
When a mobile hole is moving in an anti-ferromagnet it distorts the surrounding Neel order and forms a magnetic polaron. Such interplay between hole motion and anti-ferromagnetism…
Strong coupling Bose polarons out of equilibrium: Dynamical RG approach
Fabian Grusdt, Kushal Seetharam, Yulia Shchadilova +1
When a mobile impurity interacts with a surrounding bath of bosons, it forms a polaron. Numerous methods have been developed to calculate how the energy and the effective mass of t…
Angle-resolved photoemission spectroscopy with quantum gas microscopes
A. Bohrdt, D. Greif, E. Demler +2
Quantum gas microscopes are a promising tool to study interacting quantum many-body systems and bridge the gap between theoretical models and real materials. So far they were limit…
Strong coupling Bose polarons in a BEC
Fabian Grusdt, Richard Schmidt, Yulia E. Shchadilova +1
We use a non-perturbative renormalization group approach to develop a unified picture of the Bose polaron problem, where a mobile impurity is strongly interacting with a surroundin…
Realizing and Adiabatically Preparing Bosonic Integer and Fractional Quantum Hall states in Optical Lattices
Yin-Chen He, Fabian Grusdt, Adam Kaufman +2
We study the ground states of 2D lattice bosons in an artificial gauge field. Using state of the art DMRG simulations we obtain the zero temperature phase diagram for hardcore boso…
Bose polarons in ultracold atoms in one dimension: beyond the Fröhlich paradigm
Fabian Grusdt, Gregory E. Astrakharchik, Eugene A. Demler
Mobile impurity atoms immersed in Bose-Einstein condensates provide a new platform for exploring Bose polarons. Recent experimental advances in the field of ultracold atoms make it…
Quantum correlations at infinite temperature: the dynamical Nagaoka effect
Marton Kanasz-Nagy, Izabella Lovas, Fabian Grusdt +3
Do quantum correlations play a role in high temperature dynamics of many-body systems? A common expectation is that thermal fluctuations lead to fast decoherence and make dynamics…
Revealing Hidden Antiferromagnetic Correlations in Doped Hubbard Chains via String Correlators
Timon A. Hilker, Guillaume Salomon, Fabian Grusdt +5
Topological phases, like the celebrated Haldane phase in spin-1 chains, defy characterization through local order parameters. Instead, non-local string order parameters can be empl…
2D spin-orbit coupling for ultracold atoms in optical lattices
Fabian Grusdt, Tracy Li, Immanuel Bloch +1
Spin-orbit coupling (SOC) is at the heart of many exotic band-structures and can give rise to many-body states with topological order. Here we present a general scheme based on a c…
