Charge-Transfer States in Organic Nanowires
Charge separation processes in organic semiconductors play a pivotal role in diverse applications ranging from photovoltaics to photocatalysis. Understanding these mechanisms, particularly the role of hybrid charge-transfer (CT) states, is essential for ad ...
EPFL2024Room-Temperature Quantum Optomechanics and Free-Electron Quantum Optics
Quantum optics studies how photons interact with other forms of matter, the understanding of which was crucial for the development of quantum mechanics as a whole. Starting from the photoelectric effect, the quantum property of light has led to the develop ...
EPFL2024Resonant Tip-Enhanced Raman Spectroscopy of a Single-Molecule Kondo System
Tip-enhanced Raman spectroscopy (TERS) under ultrahigh vacuum and cryogenic conditions enables exploration of the relations between the adsorption geometry, electronic state, and vibrational fingerprints of individual molecules. TERS capability of reflecti ...
Amer Chemical Soc2024Non-Gaussian superradiant transition via three-body ultrastrong coupling
We introduce a class of quantum optical Hamiltonians characterized by three-body couplings and propose a circuit-QED scheme based on state-of-the-art technology that implements the considered model. Unlike two-body light-matter interactions, this three-bod ...
AMER PHYSICAL SOC2023Emergence of Classical Magnetic Order from Anderson Towers: Quantum Darwinism in Action
Environment is assumed to play a negative role in quantum mechanics, destroying the coherence in a quantum system and, thus, randomly changing its state. However, for a quantum system that is initially in a degenerate ground state, the situation could be d ...
College Pk2023Learning ground states of gapped quantum Hamiltonians with Kernel Methods
Giuseppe Carleo, Riccardo Rossi, Clemens Giuliani, Filippo Vicentini
Neural network approaches to approximate the ground state of quantum hamiltonians require the numerical solution of a highly nonlinear optimization problem. We introduce a statistical learning approach that makes the optimization trivial by using kernel me ...
Wien2023Machine-learning the electronic density of states: electronic properties without quantum mechanics
The electronic density of states (DOS) quantifies the distribution of the energy levels that can be occupied by electrons in a quasiparticle picture and is central to modern electronic structure theory. It also underpins the computation and interpretation ...
EPFL2023Correlation properties of a one-dimensional repulsive Bose gas at finite temperature
We present a comprehensive study shedding light on how thermal fluctuations affect correlations in a Bose gas with contact repulsive interactions in one spatial dimension. The pair correlation function, the static structure factor, and the one-body density ...
IOP Publishing Ltd2023Structure, Spin Correlations, and Magnetism of the S=1/2 Square-Lattice Antiferromagnet Sr2CuTe1-xWxO6 (0 ≤ x ≤ 1)
Henrik Moodysson Rønnow, Ellen Fogh, Peter Babkevich, Sami Juhani Vasala
Quantum spin liquids are highly entangled magnetic states with exotic properties. The S = 1/2 square-lattice Heisenberg model is one of the foundational models in frustrated magnetism with a predicted, but never observed, quantum spin liquid state. Isostru ...
Washington2023Many-body physics with strongly interacting fermions coupled to light
This thesis reports on the realization of the first experiments conducted with superfluid, strongly interacting Fermi gases of 6Li coupled to the light field of an optical cavity. In the scope of existing ultracold atomic platforms, this is the first time ...
