Spatially Nonuniform Oscillations in Ferrimagnets Based on an Atomistic Model
Xue Zhang, Baofang Cai, Jie Ren +5
The ferrimagnets, such as GdxFeCo(1-x), can produce ultrafast magnetic switching and oscillation due to the strong exchange field. The two-sublattices macrospin model has been wide…
From Elastic Spin to Phonon Spin: Symmetry and Fundamental Relations
Jie Ren
This work is mainly based on postgraduate lectures at Tongji University since 2020 spring. We firstly revisit the elastic spin and orbital angular momentum [Proc. Natl. Acad. Sci.…
Holographic Renyi entropies from hyperbolic black holes with scalar hair
Xiaoxuan Bai, Jie Ren
The Renyi entropies as a generalization of the entanglement entropy imply much more information. We analytically calculate the Renyi entropies (with a spherical entangling surface)…
Absence of measurement-induced entanglement transition due to feedback-induced skin effect
Yu-Peng Wang, Chen Fang, Jie Ren
A quantum many-body system subject to unitary evolution and repeated local measurements with an increasing rate undergoes a measurement-induced entanglement transition from extensi…
Thermodynamics of hairy accelerating black holes in gauged supergravity and beyond
Yi Wang, Jie Ren
We study the thermodynamics of accelerating asymptotically AdS black holes with scalar hair in four-dimensional Einstein-Maxwell-dilaton theories, which can be embedded in gauged s…
Long-Range Order and Quantum Criticality in Antiferromagnetic Chains with Long-Range Staggered Interactions
Jie Ren, Zhao Wang, Weixia Chen +1
We study quantum phase transitions in Heisenberg antiferromagnetic chains with a staggered power-law decaying long-range interactions. Employing the density-matrix renormalization…
