Semigroups embeddable in hyperplane face monoids
Stuart Margolis, Franco Saliola, Benjamin Steinberg
The left regular band structure on a hyperplane arrangement and its representation theory provide an important connection between semigroup theory and algebraic combinatorics. A fi…
Magneto-optical spaser
D. G. Baranov, A. P. Vinogradov, A. A. Lisyansky +2
We present an electrodynamical model of a novel quantum plasmonic device - magneto-optical spaser. It is shown that a spherical gain nanoparticle coated with a metallic magneto-opt…
Majorana states in a p-wave superconducting ring
B. Rosenstein, I. Shapiro, B. Ya. Shapiro
The spectrum of excitations of the chiral superconducting ring with internal and external radii, comparable with coherence length, trapping a unit flux is calculated. We find withi…
Imaging currents in HgTe quantum wells in the quantum spin Hall regime
Katja C. Nowack, Eric M. Spanton, Matthias Baenninger +10
The quantum spin Hall (QSH) state is a genuinely new state of matter characterized by a non-trivial topology of its band structure. Its key feature is conducting edge channels whos…
Languages cool as they expand: Allometric scaling and the decreasing need for new words
Alexander M. Petersen, Joel N. Tenenbaum, Shlomo Havlin +2
We analyze the occurrence frequencies of over 15 million words recorded in millions of books published during the past two centuries in seven different languages. For all languages…
Links arising from braid monodromy factorizations
Meirav Amram, Moshe Cohen, Mina Teicher
We investigate the local contribution of the braid monodromy factorization in the context of the links obtained by the closure of these braids. We consider plane curves which are a…
