Non-Abelian Gauge Field Mechanics
Ivan Velkovsky, Carlos Camacho, Tomoki Ozawa +2
Non-Abelian gauge fields play a key role in describing the behavior of particles whose motion is coupled to internal degrees of freedom, such as their spin. Here, we experimentally…
Hall viscosity from metric-sensitive dichroic probes
Alberto Nardin, Bruno Mera, Anaïs Defossez +3
Hall viscosity characterizes the geometric response of a quantum Hall droplet to deformations of the underlying metric, yet it has remained difficult to measure directly. We propos…
Non-equilibirum physics of density-difference dependent Hamiltonian: Quantum Scarring from Emergent Chiral Symmetry
William N Faugno, Hosho Katsura, Tomoki Ozawa
Quantum many-body scars represent a form of weak ergodicity breaking that highlights the unusual physics of thermalization in quantum systems. Understanding scar formation promises…
Anomalous Wave-Packet Dynamics in One-Dimensional Non-Hermitian Lattices
Yanyan He, Tomoki Ozawa
Non-Hermitian (NH) systems have attracted great attention due to their exotic phenomena beyond Hermitian domains. Here we study the wave-packet dynamics in general one-dimensional…
Non-Hermitian Landau Levels
Anton Montag, Tomoki Ozawa
We formulate non-Hermitian Landau levels in two-dimensional systems under a complex perpendicular magnetic field. In the symmetric gauge, we derive their discretely spaced, highly…
Gain engineering and atom lasing in a topological edge state in synthetic dimensions
Takuto Tsuno, Shintaro Taie, Yosuke Takasu +3
Recent advances in quantum technology have highlighted the importance of controlling quantum states, especially in open quantum systems, where the system interacts with the environ…
