[PDF][PDF] Perturbation theory without gauge fixing

G Parisi, YS Wu - Sci. sin, 1981 - openaccessrepository.it
We propose to formulate the perturbative expansion for field theory starting from the Langevin
equation which describes the approach to equilibrium. We show that this formulation can …

Graphene thickness determination using reflection and contrast spectroscopy

ZH Ni, HM Wang, J Kasim, HM Fan, T Yu, YH Wu… - Nano …, 2007 - ACS Publications
We have clearly discriminated the single-, bilayer-, and multiple-layer graphene (<10 layers)
on Si substrate with a 285 nm SiO 2 capping layer by using contrast spectra, which were …

Quantized Hall conductance as a topological invariant

Q Niu, DJ Thouless, YS Wu - Physical Review B, 1985 - APS
Whenever the Fermi level lies in a gap (or mobility gap) the bulk Hall conductance can be
expressed in a topologically invariant form showing the quantization explicitly. The new …

[HTML][HTML] Indirubins Inhibit Glycogen Synthase Kinase-3β and CDK5/P25, Two Protein Kinases Involved in Abnormal Tau Phosphorylation in Alzheimer's Disease: A …

…, GL Snyder, P Greengard, J Biernat, YZ Wu… - Journal of Biological …, 2001 - ASBMB
The bis-indole indirubin is an active ingredient of Danggui Longhui Wan, a traditional
Chinese medicine recipe used in the treatment of chronic diseases such as leukemias. The …

Topological quantization of the spin Hall effect in two-dimensional paramagnetic semiconductors

XL Qi, YS Wu, SC Zhang - Physical Review B, 2006 - APS
We propose models of two-dimensional paramagnetic semiconductors where the intrinsic
spin Hall effect is exactly quantized in integer units of a topological charge. The model …

Manifestations of Berry's topological phase for the photon

RY Chiao, YS Wu - Physical review letters, 1986 - APS
Recently, Berry recognized in quantum mechanics a topological phase factor arising from
the adiabatic transport of a system around a closed circuit, which is essentially the Aharonov-…

Statistical distribution for generalized ideal gas of fractional-statistics particles

YS Wu - Physical review letters, 1994 - APS
We derive the occupation-number distribution in a generalized ideal gas of particles obeying
fractional statistics, including mutual statistics, by adopting a state-counting definition. …

Implications of a cosmological constant varying as

W Chen, YS Wu - Physical Review D, 1990 - APS
We advocate the possibility that the (effective) cosmological constant Λ varies in time as R−
2, R being the scale factor of our expanding Universe. This behavior can be obtained under …

General theory for quantum statistics in two dimensions

YS Wu - Physical Review Letters, 1984 - APS
Because of complicated topology of the configuration space for indistinguishable particles
in two dimensions, Feynman's path-integral formulation allows exotic statistics. All possible …

[PDF][PDF] Pseudomonas syringae effector AvrPto blocks innate immunity by targeting receptor kinases

T Xiang, NA Zong, Y Zou, Y Wu, J Zhang, W Xing, Y Li… - Current biology, 2008 - cell.com
Plants use receptor kinases, such as FLS2 and EFR, to perceive bacterial pathogens and
initiate innate immunity. This immunity is often suppressed by bacterial effectors, allowing …
