45. Breakdown of Superposition Principle and Multipole Expansion in Emergent 2D Electromagnetism

Tom Arie Ben Ami (Universitat Augsburg)

Poster

13. Breathing and Fission of Magnetic Multi-solitons

Guillaume Brochier (MPQ)

Poster

We report the deterministic experimental realization and controlled fission of magnetic multi-soliton states in a uniform quasi-one-dimensional immiscible two-component Bose gas. We explore the Manakov regime, where the spin dynamics is well-described by the easy-axis Landau-Lifshitz equation (LLE). The gauge equivalence between the easy-axis LLE and the attractive nonlinear Schrödinger...

12. Dynamical Heterogeneity and fractal subdiffusive transport in spin-ice

Malte Bieringer (MDPK)

Poster

Dynamical heterogeneity, fractality, and topology are central concepts in modern condensed matter physics. Their origin is typically rooted in very different physical settings and microscopic mechanisms, such as glassy dynamics, quenched disorder and the absence of symmetry breaking. We show here that a simple, clean lattice model -- in thermal equilibrium -- hosts all three simultaneously....

25. Dynamical optical lattices for quantum simulation and enhanced readout

David Gröters (Max Planck Institute of Quantum Optics)

Poster

Optical lattice-based quantum simulators are ideal platforms to study correlated systems and non-ergodic dynamics on the single-atom level. In those systems, the lattice structure is typically fixed by a static beam geometry, restricting mid-sequence adaptations. Here, we present our recent progress in implementing passively phase-stable tuneable optical lattices, allowing us to dynamically...

49. Engineer kinetically constrained dynamics based on a two-species Bose-Fermi-Hubbard Hamiltonian

Felix Stephan (Uni Tübingen)

Poster

Understanding the dynamics of closed many-body quantum systems out of equilibrium remains a central challenge in modern physics. Thermalizing behavior is captured by the Eigenstate Thermalization Hypothesis (ETH), which predicts that individual eigenstates of a quantum many-body Hamiltonian locally reproduce thermal expectation values. In recent years, violations of ETH have been observed in...

22. ETH analysis of the spin-polaron in the Kondo lattice model

Mica Rene Schwarm (UYST)

Poster

The mechanism behind thermalizing quantum systems remains a much discussed topic up to this day. Recent developments such as the eigenstate thermalization hypothesis (ETH) and random matrix theory helped establish a theoretical model for the relaxation behaviour of closed quantum systems. In this work we are using exact diagonalization to investigate the ETH behaviour of the one-dimensional...

21. From Classical Stochastic to Monitored Quantum Dynamics: Dynamical Phase Coexistence in East Circuit Models

Marcel Cech

Poster

Kinetically constrained models have been widely studied in the context of glass formers and non-equilibrium statistical mechanics. Although their simple local rules often result in structureless static properties, their dynamics exhibit intricate emergent phenomena. In this work, we investigate monitored quantum circuit models that interpolate between classical stochastic and unitary quantum...

24. Glassy Dynamics in a Bond-Disordered Quantum Spin Model from an ETH Perspective

Phillip Teschner (UYST)

Poster

We investigate the non-equilibrium properties of the anisotropic Heisenberg spin glass model that evolves under unitary dynamics. As the interaction between the spins increases, the model undergoes a transition from an ergodic to a non-ergodic regime. We examine this transition by calculating measures indicating a violation of random-matrix-like behavior and the eigenstate thermalization...

27. Quantum-gas mixtures with extreme mass imbalance

Kirill Karpov (University of Tübingen)

Poster

The extreme mass imbalance between Er and Li offers a unique platform for exploring impurity physics and emergent many-body phenomena. In this experiment, we produce a double-degenerate mixture of 166Er and 6Li.
Efficient evaporation of erbium allows sympathetic cooling of lithium.
Furthermore, the tune-out wavelength of Er enables species-selective confinement. This allows for the...

15. Space-time correlations in monitored kinetically constrained quantum systems

Igor Lesanovsky (GNOI)

Poster

State-of-the-art quantum simulators permit local temporal control
of interactions and midcircuit readout. These capabilities open the
way towards the exploration of intriguing nonequilibrium phenomena.
We illustrate this with a kinetically constrained many-body quantum
system that has a natural implementation on (dual-species) Rydberg
quantum simulators [1]. The evolution proceeds in...

23. Stability of subdiffusion in dipole-conserving models

Francisco Guzman Cajica (Georg-August-Universität Göttingen)

Poster

In this project, we study one-dimensional quantum spin chains with constraint dynamics. The constrain is that an additional quantity, the first moment of the magnetization, is conserved. It has previously been observed that models with this additional conservation law exhibit slow dynamics; in particular, we focus on the magnetization transport, which is subdiffusive. It is of particular...

17. Tight-binding models for Li-Er mixtures in optical lattices

Simon Bode (FHM Group)

Poster

We explain how we are planning to extract the parameters of a many-body tight-binding model for Li-Er mixtures with effective off-diagonal disorder in an optical lattice from a double-well potential.
