WebJul 29, 2024 · The nature of fore-wake excitations created by a charge bunch moving in a magnetized plasma is investigated using particle-in-cell simulations. Our studies establish for the first time the existence of precursor magneto-sonic solitons traveling ahead of a moving charge bunch. Webeld could be the chiral soliton lattice (CSL) made of bosonic neutral pion ˇ0 instead of fermionic baryons [1{5]. Following this lead, related phases involving charged pions have then been studied, including the charged pion condensate [3] and its competition with an Abrikosov vortex lattice [6], for which one can draw the phase diagram ... heart nhs test https://joaodalessandro.com

WebBoth direct photogeneration of charged-soliton pairs and neutral- to charged-soliton conversion are observed. The former are created by intrachain absorption and decay on a subpicosecond time scale. The latter are formed following interchain photoexcitation and are the dominant population of charged solitons at times greater than 20 ps. WebThe magnitude of quantum fluctuations of the charge of a fractionally charged soliton is calculated. The soliton charge operator is defined as Q ^ s = Q ^ f − 〈 0 Q ^ f 0 〉, where Q ^ f is the integral of the charge-density operator sampled by a function f peaked at the position of the soliton, and falling smoothly to zero on a scale L.
