Low-Rank Tensor Methods for High-Dimensional Problems
In this thesis, we propose and analyze novel numerical algorithms for solving three different high-dimensional problems involving tensors. The commonality of these problems is that the tensors can potentially be well approximated in low-rank formats. Ident ...
EPFL2023Effect of a temperature gradient on the screening properties of ionic fluids
Federico Grasselli, Andrea Grisafi
The electrostatic screening properties of ionic fluids are of paramount importance in countless physical processes. Yet the screening behavior of ionic conductors out of thermal equilibrium has to date mainly been studied in the context of thermoelectric p ...
AMER PHYSICAL SOC2023Identifying Large Charge operators
Riccardo Rattazzi, Alexander Monin, Gil Badel
The Large Charge sector of Conformal Field Theory (CFT) can generically be described through a semiclassical expansion around a superfluid background. In this work, focussing on U(1) invariant Wilson-Fisher fixed points, we study the spectrum of spinning l ...
SPRINGER2023Normalized Gaussian path integrals
Path integrals play a crucial role in describing the dynamics of physical systems subject to classical or quantum noise. In fact, when correctly normalized, they express the probability of transition between two states of the system. In this work, we show ...
AMER PHYSICAL SOC2020Tunneling Splittings in Water Clusters from Path Integral Molecular Dynamics
Christophe Louis Joseph Jean-Luc Vaillant
We present calculations of tunneling splittings in selected small water clusters, based on a recently developed path integral molecular dynamics (PIMD) method. The ground-rotational-state tunneling motions associated with the largest splittings in the wate ...
