Quantum chaos in many-body systems of indistinguishable particles
Juan-Diego Urbina, Klaus Richter
In quantum systems with a classical limit, advanced semiclassical methods provide the crucial link between phase-space structures, reflecting the distinction between chaotic, mixed…

Quantum Chaos as an Essential Resource for Full Quantum State Controllability
Lukas Beringer, Mathias Steinhuber, Klaus Richter +1
Using the key properties of chaos, i.e. ergodicity and exponential instability, as a resource to control classical dynamics has a long and considerable history. However, in the con…

Universal correlations in chaotic many-body quantum states: Fock-space formulation of Berrys random wave model
Florian Schoeppl, Remy Dubertrand, Juan-Diego Urbina +1
The apparent randomness of chaotic eigenstates in interacting quantum systems hides subtle correlations dynamically imposed by their finite energy per particle. These correlations…
