Hamiltonian engineering for quantum sensing and quantum simulation
… broad applications. In this thesis, we explore Hamiltonian engineering techniques to build better quantum sensors and quantum simulators. In quantum sensing, advanced control techniques are required to extract all the information available about the sensing target from the sensor. Unfortunately, …

NMR studies of quantum thermalization
… control sequences, novel states, observables and Hamiltonians are created to explore and characterize various quantum thermalization phenomena. Leveraging the intrinsic disorder, a novel method to detect spin dynamics at single-site level is introduced. The method is applied to study hydrodynamics …

Prethermalization and localization in quantum spin chains
… spin systems with magnetic resonance techniques. Hamiltonian engineering enables tuning the strength of spin-spin interactions and of a transverse magnetic field in a spin chain system, as well as to invert the Hamiltonian sign to reveal OTO correlations. The experiments reveal that at high fields …

Quantum assisted sensing, simulation and control
… control of spin systems can be achieved via Hamiltonian engineering based on the creation of dynamical filters and/or the use of a quantum actuator, with novel implications in quantum simulation. We also enhance the available quantum control, sensing and simulation methods by the use of …

Probing proximity-induced superconductivity in Nb- Bi2Se3 bilayers with low-temperature transport and Josephson interferometry
… resembles a spinless p-wave superconducting Hamiltonian. This work explores the limits of Hamiltonian engineering in superconductor-topological insulator bilayers made of niobium and bismuth selenide. Low temperature transport measurements demonstrate the presence of proximity-induced …

The cold atom toolbox in momentum space
… lasers has led to a more bottom-up approach to engineering lattice models. In this thesis, we present our ""momentum-space lattice"" technique in which we use individual laser frequencies to couple the momentum states of a rubidium-87 Bose-Einstein condensate, in order to create lattices with …
