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…
