Stark Many-Body Localisation Under Periodic Driving
Christian Duffin, Aydin Deger, Achilleas Lazarides
We study stability of localisation under periodic driving in many-body Stark systems. We find that localisation is stable except near special resonant frequencies, where resonances…
Probing quantum properties of black holes with a Floquet-driven optical lattice simulator
Asmae Benhemou, Georgia Nixon, Aydin Deger +2
In the curved spacetime of a black hole, quantum physics gives rise to distinctive effects such as Hawking radiation and maximally fast scrambling. Here, we present a scheme for an…
Weak ergodicity breaking transition in randomly constrained model
Aydin Deger, Achilleas Lazarides
Experiments in Rydberg atoms have recently found unusually slow decay from a small number of special initial states. We investigate the robustness of such long-lived states (LLS) b…
Persistent non-Gaussian correlations in out-of-equilibrium Rydberg atom arrays
Aydin Deger, Aiden Daniel, Zlatko Papić +1
Gaussian correlations emerge in a large class of many-body quantum systems quenched out of equilibrium, as demonstrated in recent experiments on coupled one-dimensional superfluids…
AdS/CFT Correspondence with a 3D Black Hole Simulator
Aydin Deger, Matthew D. Horner, Jiannis K. Pachos
One of the key applications of AdS/CFT correspondence is the duality it dictates between the entanglement entropy of Anti-de Sitter (AdS) black holes and lower-dimensional conforma…
Constrained Dynamics and Directed Percolation
Aydin Deger, Achilleas Lazarides, Sthitadhi Roy
In a recent work [A. Deger et al., Phys. Rev. Lett. 129, 160601 (2022)] we have shown that kinetic constraints can completely arrest many-body chaos in the dynamics of a classical,…
Arresting classical many-body chaos by kinetic constraints
Aydin Deger, Sthitadhi Roy, Achilleas Lazarides
We investigate the effect of kinetic constraints on classical many-body chaos in a translationally-invariant Heisenberg spin chain using a classical counterpart of the out-of-time-…
Nonequilibrium phase transition in a single-electron micromaser
Fredrik Brange, Aydin Deger, Christian Flindt
Phase transitions occur in a wide range of physical systems and are characterized by the abrupt change of a physical observable in response to the variation of an external control…
Emergence of Gaussianity in the thermodynamic limit of interacting fermions
Gabriel Matos, Andrew Hallam, Aydin Deger +2
Systems of interacting fermions can give rise to ground states whose correlations become effectively free-fermion-like in the thermodynamic limit, as shown by Baxter for a class of…
Determination of dynamical quantum phase transitions in strongly correlated many-body systems using Loschmidt cumulants
Sebastiano Peotta, Fredrik Brange, Aydin Deger +2
Dynamical phase transitions extend the notion of criticality to non-stationary settings and are characterized by sudden changes in the macroscopic properties of time-evolving quant…
Lee-Yang theory, high cumulants, and large-deviation statistics of the magnetization in the Ising model
Aydin Deger, Fredrik Brange, Christian Flindt
We investigate the Ising model in one, two, and three dimensions using a cumulant method that allows us to determine the Lee-Yang zeros from the magnetization fluctuations in small…
Lee-Yang theory of the Curie-Weiss model and its rare fluctuations
Aydin Deger, Christian Flindt
Phase transitions are typically accompanied by non-analytic behaviors of the free energy, which can be explained by considering the zeros of the partition function in the complex p…
Determination of universal critical exponents using Lee-Yang theory
Aydin Deger, Christian Flindt
Lee-Yang zeros are points in the complex plane of an external control parameter at which the partition function vanishes for a many-body system of finite size. In the thermodynamic…
Lee-Yang zeros and large-deviation statistics of a molecular zipper
Aydin Deger, Kay Brandner, Christian Flindt
The complex zeros of partition functions were originally investigated by Lee and Yang to explain the behavior of condensing gases. Since then, Lee-Yang zeros have become a powerful…
Geometric Entanglement and Quantum Phase Transition in Generalized Cluster-XY models
Aydin Deger, Tzu-Chieh Wei
In this work, we investigate quantum phase transition (QPT) in a generic family of spin chains using the ground-state energy, the energy gap, and the geometric measure of entanglem…
