Chiral splitting and world-sheet gravitinos in higher-derivative string amplitudes
Kasper Peeters, Pierre Vanhove, Anders Westerberg
We report on progress made in the construction of higher-derivative superinvariants for type-II theories in ten dimensions. The string amplitude calculations required for this anal…
Interacting Dark Matter disguised as Warm Dark Matter
Celine Boehm, Alain Riazuelo, Steen H. Hansen +1
We explore some of the consequences of Dark Matter-photon interactions on structure formation, focusing on the evolution of cosmological perturbations and performing both an analyt…
Vector Manifestation and Fate of Vector Mesons in Dense Matter
Masayasu Harada, Youngman Kim, Mannque Rho
We describe in-medium properties of hadrons in dense matter near chiral restoration using a Wilsonian matching to QCD of an effective field theory with hidden local symmetry at the…
What is the fate of the heavy electron at a quantum critical point?
P. Coleman, C. Pepin
A growing body of evidence suggests that the quantum critical behavior at the onset of magnetism in heavy fermion systems can not be understood in terms of a simple quantum spin de…
A Classification of random Dirac fermions
Denis Bernard, Andre' LeClair
We present a detailed classification of random Dirac hamiltonians in two spatial dimensions based on the implementation of discrete symmetries. Our classification is slightly finer…
Renormalization group for network models of Quantum Hall transitions
Denis Bernard, Andre LeClair
We analyze in detail the renormalization group flows which follow from the recently proposed all orders beta functions for the Chalker-Coddington network model. The flows in the ph…
