The Yang-Lee edge singularity was originally studied from the standpoint of mathematical
foundations of phase transitions. However, direct observation of anomalous scaling with the …

Employing the functional renormalization group approach at next-to-leading order of the
derivative expansion, we refine our earlier findings for the location of the Yang-Lee edge …

Partition functions are ubiquitous in physics: They are important in determining the
thermodynamic properties of many-body systems and in understanding their phase …

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 …

We determine the universal location of the Yang–Lee edge singularity in the entire relevant
domain of spatial dimensions 1≤ d≤ 4 for the Ising universality class. To that end, we …

The Yang-Lee edge singularity is a quintessential nonunitary critical phenomenon
characterized by anomalous scaling. However, an imaginary magnetic field involved in this …

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 …

In this work, we show that a universal quantum work relation for a quantum system driven
arbitrarily far from equilibrium extends to a parity-time-(PT-) symmetric quantum system with …

The Yang-Lee edge singularity is an intriguing critical phenomenon characterized by
nonunitary field theory. However, its experimental realization for interacting many-body …

Lee‐Yang zeros lie on the complex plane of the control parameters for many‐body systems
with finite size, such as the transverse magnetic field and the inverse temperature. Here, an …
