The Auslander-Reiten formula for complexes of modules
Henning Krause, Jue Le
An Auslander-Reiten formula for complexes of modules is presented. This formula contains as a special case the classical Auslander Reiten formula. The Auslander-Reiten translate of…
Spin Hall effect in a Doped Mott Insulator
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
The existence of conserved spin Hall currents is shown in a strongly correlated system without involving spin-orbit coupling. The spin Hall conductivity is determined by intrinsic…
Representation theory of towers of recollement: theory, notes, and examples
Anton Cox, Paul Martin, Alison Parker +1
We give an axiomatic framework for studying the representation theory of towers of algebras. We introduce a new class of algebras, contour algebras, generalising (and interpolating…
Mutual-Chern-Simons effective theory of doped antiferromagnets
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
A mutual-Chern-Simons Lagrangian is derived as a minimal field theory description of the phase-string model for doped antiferromagnets. Such an effective Lagrangian is shown to ret…
Intermediate-band Photometry of Type Ia Supernovae
Xiaofeng Wang, Xu Zhou, Tianmeng Zhang +1
We present optical light curves of five Type Ia supernovae (2002er, 2002fk, 2003cg, 2003du, 2003fk). The photometric observations were performed in a set of intermediate-band filte…
The L-functions of twisted Witt extensions
Chunlei Liu
The L-function of a non-degenerate twisted Witt extension is proved to be a polynomial. Its Newton polygon is proved to lie above the Hodge polygon of that extension. And the Newto…
