Hochschild cohomology with support
Wendy Lowen
In this paper we investigate the functoriality properties of map-graded Hochschild complexes. We show that the category MAP of map-graded categories is naturally a stack over the c…
Melting of graphene clusters
Sandeep Kumar Singh, M. Neek-Amal, F. M. Peeters
Density-functional tight-binding and classical molecular dynamics simulations are used to investigate the structural deformations and melting of planar carbon nano-clusters …
Ginzburg-Landau theory for multiband superconductors: microscopic derivation
N. V. Orlova, A. A. Shanenko, M. V. Milošević +3
A procedure to derive the Ginzburg-Landau (GL) theory from the multiband BCS Hamiltonian is developed in a general case with an arbitrary number of bands and arbitrary interaction…
Anomalous Raman Spectra and Thickness Dependent Electronic properties of WSe2
H. Sahin, S. Tongay, S. Horzum +5
Typical Raman spectra of transition metal dichalcogenides (TMDs) display two prominent peaks, E2g and A1g, that are well separated from each other. We find that these modes are deg…
Quasi-Frobenius-Lusztig kernels for simple Lie algebras
Gongxiang Liu, Fred Van Oystaeyen, Yinhuo Zhang
In this paper, we construct the quasi-Frobenius-Lusztig kernel for any simple Lie algebra .
Resonant valley filtering of massive Dirac electrons
D. Moldovan, M. Ramezani Masir, L. Covaci +1
Electrons in graphene, in addition to their spin, have two pseudospin degrees of freedom: sublattice and valley pseudospin. Valleytronics uses the valley degree of freedom as a car…
