Palatini frames in scalar-tensor theories of gravity
Aleksander Kozak, Andrzej Borowiec
A new systematic approach extending the notion of frames to the Palatini scalar-tensor theories of gravity in various dimensions n>2 is proposed. We impose frame transformation ind…
Exploring universal and non-universal regimes of trimers from three-body interactions in one-dimensional lattices
Arthur Christianen, John Sous
We investigate the formation of trimers in an infinite one-dimensional lattice model of hard-core particles with single-particle hopping and and nearest-neighbour two-body …
Light Bipolarons Stabilized by Peierls Electron-Phonon Coupling
John Sous, Monodeep Chakraborty, Roman V. Krems +1
It is widely accepted that phonon-mediated high-temperature superconductivity is impossible at ambient pressure, because of the very large effective masses of polarons/bipolarons a…
Extrapolating quantum observables with machine learning: Inferring multiple phase transitions from properties of a single phase
Rodrigo A. Vargas-Hernández, John Sous, Mona Berciu +1
We present a machine-learning method for predicting sharp transitions in a Hamiltonian phase diagram by extrapolating the properties of quantum systems. The method is based on Gaus…
