Enhanced curvature perturbations from spherical domain walls nucleated during inflation
Zhen-Min Zeng, Jing Liu, Zong-Kuan Guo
We investigate spherical domain walls~(DWs) nucleated via quantum tunneling in multifield inflationary models and curvature perturbations induced by the inhomogeneous distribution…
Generation of gravitational waves in dynamical Chern-Simons gravity
Zhi-Zhang Peng, Zhen-Min Zeng, Chengjie Fu +1
We investigate gravitational waves (GWs) generated in a two-field inflationary model with a non-canonical kinetic term, in which the gravitational Chern-Simons term is coupled to a…
Low-temperature specific-heat studies on two square-kagome antiferromagnets
Bo Liu, Zhenyuan Zeng, Aini Xu +5
We studied the low-temperature specific heats of two antiferromagnets with the two-dimensional square-kagome structure, i.e., KCuAlBiO(SO)Cl (KCu6) and NaCu…
Possible Dirac quantum spin liquid in a kagome quantum antiferromagnet YCu(OH)Br[Br(OH)]
Zhenyuan Zeng, Xiaoyan Ma, Si Wu +13
We studied the magnetic properties of YCu(OH)Br[Br(OH)] ( = 0.33), where Cu ions form two-dimensional kagome layers. There is no magnetic order…
Neutron spin resonance in a quasi-two-dimensional iron-based superconductor
Wenshan Hong, Linxing Song, Bo Liu +15
Magnetically mediated Cooper pairing is generally regarded as a key to establish the unified mechanism of unconventional superconductivity. One crucial evidence is the neutron spin…
Maximum Entropy Principle for Self-gravitating Perfect Fluid in Lovelock Gravity
Li-Ming Cao, Jianfei Xu, Zhe Zeng
We consider a static self-gravitating system consisting of perfect fluid with isometries of an -dimensional maximally symmetric space in Lovelock gravity theory. A straightf…
