Arpita Mitra, Run Xiao, Wilson Yanez, Yongxi Ou, Juan Chamorro, Tyrel M. McQueen, Alexander Grutter, Julie A. Borchers, Michael R. Fitzsimmons, Timothy Charlton, Nitin Samarth
Breaking time-reversal symmetry in a Dirac semimetal Cd3As2 through doping with magnetic ions or by the magnetic proximity effect is expected to cause a transition to other topological phases (such as a Weyl semimetal). To this end, we investigate the

Evaluation of 3D Curvature and Lead Stress of Transvenous Right Ventricular Leads: The Human Use Conditions Study (HUCS)
