Generalized local Tb Theorems for Square Functions, and applications
Ana Grau de la Herran, Steve Hofmann
A local Tb theorem is an L^2 boundedness criterion by which the question of the global behavior of an operator is reduced to its local behavior, acting on a family of test function…
Realignment Entanglement Criterion for Continuous Bipartite Symmetric Quantum States
Xiao-yu Chen, Li-zhen Jiang, Ping Yu +1
The separability of bipartite non-Gaussian states is studied by applying the realignment criterion with the technique of functional analysis. The realignment criterion is given as…
Magnetism and electronic properties of BiFeO3 under lower pressure
Hong-Jian Feng
Ab initio calculations show an antiferromagnetic-ferromagnetic phase transition around 9-10 GPa and a magnetic anomaly at 12 GPa in BiFeO3. The magnetic phase transition also invol…
The role of Coulomb and exchange interaction on the Dzyaloshinskii-Moriya interaction(DMI) in BiFeO3
Hong-Jian Feng
Ab initio calculations show that the Dzyaloshinskii-Moriya interaction(DMI)and net magnetization per unit cell in BiFeO3 are reduced when U is increasing from 0 to 2.9 eV, and inde…
Light rays, gravitational waves, and pulse-time offsets
Adam Helfer
One might expect light to be scattered when it passes through a gravitational wave, and might hope that in favourable circumstances these scatterings could be observed on Earth eve…
Detection of selective sweeps in cattle using genome-wide SNP data
Holly R. Ramey, Jared E. Decker, Stephanie D. McKay +3
The domestication and subsequent selection by humans to create breeds of cattle undoubtedly altered the patterning of variation within their genomes. Strong selection to fix advant…
