Maximal coin-position entanglement and non-Hermitian skin effect in discrete-time quantum walks
Ding Cheng, Yi Li, Hao Zhao +6
A distinctive feature of non-Hermitian systems is the skin effect, which has attracted widespread attention in recent studies. Quantum walks provide a powerful platform for explori…
Revealing Fano Resonance in Dirac Materials ZrTe5 through Raman Scattering
Di Cheng, Tao Jiang, Feng Zhang +10
We explore the Fano resonance in ZrTe5, using Raman scattering measurements. We identified two closely spaced B2g phonon modes, B2g I and B2g II, around 9 meV and 10 meV, respectiv…
Observation of the Magnonic Dicke Superradiant Phase Transition
Dasom Kim, Sohail Dasgupta, Xiaoxuan Ma +16
Two-level atoms coupled with single-mode cavity photons are predicted to exhibit a quantum phase transition when the coupling strength exceeds a critical value, entering a phase in…
Discovery of an Unconventional Quantum Echo by Interference of Higgs Coherence
C. Huang, M. Mootz, L. Luo +9
Nonlinearities in quantum systems are fundamentally characterized by the interplay of phase coherences, their interference, and state transition amplitudes. Yet the question of how…
Evidence for highly damped Higgs mode in infinite-layer nickelates
Bing Cheng, Di Cheng, Kyuho Lee +10
The dynamics of Higgs mode in superconductors, manifested as coherent oscillations of the superconducting order parameter amplitude, provides vital insights into the nature of the…
Low-energy electrodynamics of infinite-layer nickelates: evidence for d-wave superconductivity in the dirty limit
Bing Cheng, Di Cheng, Kyuho Lee +9
The discovery of superconductivity in infinite-layer nickelates establishes a new category of unconventional superconductors that share structural and electronic similarities with…
