Preparation of excited states for nuclear dynamics on a quantum computer
Alessandro Roggero, Chenyi Gu, Alessandro Baroni +1
We study two different methods to prepare excited states on a quantum computer, a key initial step to study dynamics within linear response theory. The first method uses unitary ev…

Exact representations of many body interactions with RBM neural networks
Ermal Rrapaj, Alessandro Roggero
Restricted Boltzmann Machines (RBM) are simple statistical models defined on a bipartite graph which have been successfully used in studying more complicated many-body systems, bot…

Spectral density estimation with the Gaussian Integral Transform
Alessandro Roggero
The spectral density operator plays a central role in linear response theory as its expectation value, the dynamical response function, can be used to compu…
