Adaptive projected variational quantum dynamics
Giuseppe Carleo, Stefano Barison, David Linteau
We propose an adaptive quantum algorithm to prepare accurate variational time evolved wave functions. The method is based on the projected variational quantum dynamics (pVQD) algorithm, that performs a global optimization with linear scaling in the number ...
Amer Physical Soc2024Hausdorff dimension of fermions on a random lattice
Geometric properties of lattice quantum gravity in two dimensions are studied numerically via Monte Carlo on Euclidean Dynamical Triangulations. A new computational method is proposed to simulate gravity coupled with fermions, which allows the study of int ...
Elsevier2024Physical and unphysical regimes of self-consistent many-body perturbation theory
In the standard framework of self-consistent many-body perturbation theory, the skeleton series for the self-energy is truncated at a finite order N and plugged into the Dyson equation, which is then solved for the propagator G(N). We consider two examples ...
Scipost Foundation2024Bounds on photon scattering
Denis Karateev, Kelian Philippe Häring, Marco Meineri, Aditya Hebbar
We study 2-to-2 scattering amplitudes of massless spin one particles in space-time dimensions, like real world photons. We define a set of non-perturbative observables (Wilson coefficients) which describe these amplitudes at low energies. We use full ...
2022Fermionic wave functions from neural-network constrained hidden states
We introduce a systematically improvable family of variational wave functions for the simulation of strongly correlated fermionic systems. This family consists of Slater determinants in an augmented Hilbert space involving “hidden” additional fermionic deg ...
2022Experimental Observation and Spin Texture of Dirac Node Arcs in Tetradymite Topological Metals
Emmanouil Frantzeskakis, Ji Dai
We report the observation of a nontrivial spin texture in Dirac node arcs, i.e., novel topological objects formed when Dirac cones of massless particles extend along an open one-dimensional line in momentum space. We find that such states are present in al ...
