Constrained many-body phases in a -Higgs lattice gauge theory
Alexander Schuckert, Stefan Kühn, Kevin C. Smith +2
We study the ground-state phase diagram of a one-dimensional lattice gauge theory coupled to soft-core bosonic matter at unit filling, inspired by the Higgs sector o…
Emergence of Fermi's Golden Rule in the Probing of a Quantum Many-Body System
Jianyi Chen, Songtao Huang, Yunpeng Ji +5
Fermi's Golden Rule (FGR) is one of the most impactful formulas in quantum mechanics, providing a link between easy-to-measure observables - such as transition rates - and fundamen…
The strongly driven Fermi polaron
Franklin J. Vivanco, Alexander Schuckert, Songtao Huang +6
Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. Therefore, the prospect of manipulating their properties wit…
Ultracold plasmas from strongly anti-correlated Rydberg gases in the Kinetic Field Theory formalism
Elena Kozlikin, Robert Lilow, Martin Pauly +4
The dynamics of correlated systems is relevant in many fields ranging from cosmology to plasma physics. However, they are challenging to predict and understand even for classical s…
Coupled Hydrodynamics in Dipole-Conserving Quantum Systems
A. G. Burchards, J. Feldmeier, A. Schuckert +1
We investigate the coupled dynamics of charge and energy in interacting lattice models with dipole conservation. We formulate a generic hydrodynamic theory for this combination of…
Visualizing spinon Fermi surfaces with time-dependent spectroscopy
Alexander Schuckert, Annabelle Bohrdt, Eleanor Crane +1
Quantum simulation experiments have started to explore regimes that are not accessible with exact numerical methods. In order to probe these systems and enable new physical insight…
Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations
Alexander Schuckert, Michael Knap
The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. So far, however, experimental studi…
Non-local emergent hydrodynamics in a long-range quantum spin system
Alexander Schuckert, Izabella Lovas, Michael Knap
Generic short-range interacting quantum systems with a conserved quantity exhibit universal diffusive transport at late times. We employ non-equilibrium quantum field theory and se…
Non-equilibrium Quantum Spin Dynamics from 2PI Functional Integral Techniques in the Schwinger Boson Representation
A. Schuckert, A. Piñeiro Orioli, J. Berges
We present a non-equilibrium quantum field theory approach to the initial-state dynamics of spin models based on two-particle irreducible (2PI) functional integral techniques. It e…
