Relation between winding numbers and energy dispersions
Quancheng Liu, Klaus Ziegler
Two-band Hamiltonians provide a typical description of topological band structures, in which the eigenfunctions can be characterized by a %Bloch vector field whose winding number t…
Entanglement of bosonic systems under monitored evolution
Quancheng Liu, Klaus Ziegler
The evolution of non-interacting bosons in the presence of repeated projective measurements is studied. Following the established approach, this monitored evolution is characterize…
Fractionally Quantized Recurrence Detection Times in Monitored Quantum Many-Body Systems
Quancheng Liu, Sabine Tornow, David A. Kessler +1
Recurrence time quantifies the duration required for a physical system to return to its initial state, playing a pivotal role in understanding the predictability of complex systems…
Inverse orbital Hall effect and orbitronic terahertz emission observed in the materials with weak spin-orbit coupling
Ping Wang, Zheng Feng, Yuhe Yang +8
The Orbital Hall effect, which originates from materials with weak spin-orbit coupling, has attracted considerable interest for spin-orbitronic applications. Here, we demonstrate t…
Entanglement transition through Hilbert-space localization
Quancheng Liu, Klaus Ziegler
We study Hilbert-space localization of the many-body dynamics due to ergodicity breaking and analyze this effect in terms of the entanglement entropy and the entanglement spectrum.…
No-go theorems for deterministic purification and probabilistic enhancement of coherence
Qiming Ding, Quancheng Liu
The manipulation of quantum coherence is one of the principal issues in the resource theory of coherence, with two critical topics being the purification and enhancement of coheren…
Designing exceptional-point-based graphs yielding topologically guaranteed quantum search
Quancheng Liu, David A. Kessler, Eli Barkai
Quantum walks underlie an important class of quantum computing algorithms, and represent promising approaches in various simulations and practical applications. Here we design stro…
Driving quantum systems with repeated conditional measurements
Quancheng Liu, Klaus Ziegler, David A. Kessler +1
We investigate the effect of conditional null measurements on a quantum system and find a rich variety of behaviors. Specifically, quantum dynamics with a time independent in a…
