Characterizing Topological Excitations of a Long-Range Heisenberg Model with Trapped Ions
Stefan Birnkammer, Annabelle Bohrdt, Fabian Grusdt +1
Realizing and characterizing interacting topological phases in synthetic quantum systems is a formidable challenge. Here, we propose a Floquet protocol to realize the antiferromagn…
lattice gauge theories and Kitaev's toric code: A scheme for analog quantum simulation
Lukas Homeier, Christian Schweizer, Monika Aidelsburger +2
Kitaev's toric code is an exactly solvable model with -topological order, which has potential applications in quantum computation and error correction. However, a dir…
Radiofrequency spectroscopy of one-dimensional trapped Bose polarons: crossover from the adiabatic to the diabatic regime
S. I. Mistakidis, G. M. Koutentakis, F. Grusdt +2
We investigate the crossover of the impurity-induced dynamics, in trapped one-dimensional Bose polarons subject to radio frequency (rf) pulses of varying intensity, from an adiabat…
Bosonic Pfaffian State in the Hofstadter-Bose-Hubbard Model
Felix A. Palm, Maximilian Buser, Julian Léonard +3
Topological states of matter, such as fractional quantum Hall states, are an active field of research due to their exotic excitations. In particular, ultracold atoms in optical lat…
Microscopic evolution of doped Mott insulators from polaronic metal to Fermi liquid
Joannis Koepsell, Dominik Bourgund, Pimonpan Sompet +8
The competition between antiferromagnetism and hole motion in two-dimensional Mott insulators lies at the heart of a doping-dependent transition from an anomalous metal to a conven…
Dominant fifth-order correlations in doped quantum anti-ferromagnets
A. Bohrdt, Y. Wang, J. Koepsell +3
Traditionally one and two-point correlation functions are used to characterize many-body systems. In strongly correlated quantum materials, such as the doped 2D Fermi-Hubbard syste…
Z2 parton phases in the mixed-dimensional model
Fabian Grusdt, Lode Pollet
We study the interplay of spin- and charge degrees of freedom in a doped Ising antiferromagnet, where the motion of charges is restricted to one dimension. The phase diagram of thi…
Coupling a mobile hole to an antiferromagnetic spin background: Transient dynamics of a magnetic polaron
Geoffrey Ji, Muqing Xu, Lev Haldar Kendrick +8
Understanding the interplay between charge and spin and its effects on transport is a ubiquitous challenge in quantum many-body systems. In the Fermi-Hubbard model, this interplay…
Skyrmion Ground States of Rapidly Rotating Few-Fermion Systems
Lukas Palm, Fabian Grusdt, Philipp M. Preiss
We show that ultracold fermions in an artificial magnetic field open up a new window to the physics of the spinful fractional quantum Hall effect. We numerically study the lowest e…
Ramsey interferometry of non-Hermitian quantum impurities
F. Tonielli, N. Chakraborty, F. Grusdt +1
We introduce a Ramsey pulse scheme which extracts the non-Hermitian Hamiltonian associated to an arbitrary Lindblad dynamics. We propose a realted protocol to measure via interfero…
Parton theory of ARPES spectra in anti-ferromagnetic Mott insulators
Annabelle Bohrdt, Eugene Demler, Frank Pollmann +2
Angle-resolved photoemission spectroscopy (ARPES) has revealed peculiar properties of mobile dopants in correlated anti-ferromagnets (AFMs). But describing them theoretically, even…
