Zeros of Fourier spectrum – The atypical case of the Riemann Zeta function

In this article we will study the spectral properties of a deterministic signal exponentially damped in the past and in the future (the damping in the future is controlled by a time constant). The ...

Partition function zeros are ‘shortcut’ to thermodynamic calculations on quantum computers

A study has developed a new method that enables quantum computers to measure the thermodynamic properties of systems by calculating the zeros of the partition function. A study led by researchers at ...
