Quantum Journal Club: Probing Johnson noise and ballistic transport in normal me
Abstract: Thermally induced electrical currents, known as Johnson noise, cause fluctuating electric and magnetic fields in proximity to a conductor. These fluctuations are intrinsically related to th...

Engineering Hierarchical Symmetries and Massive Nambu-Goldstone Modes
Abstract: We present a general driving protocol for many-body systems to generate a sequence of prethermal regimes, each exhibiting a lower symmetry than the preceding one [1]. We provide an explicit...
