    "abstract": "We present a method of simulating the Dirac equation in 3+1 dimensions for a\nfree spin-1/2 particle in a single trapped ion. The Dirac bispinor is\nrepresented by four ionic internal states, and position and momentum of the\nDirac particle are associated with the respective ionic variables. We show also\nhow to simulate the simplified 1+1 case, requiring the manipulation of only two\ninternal levels and one motional degree of freedom. Moreover, we study relevant\nquantum-relativistic effects, like the Zitterbewegung and Klein\u0027s paradox, the\ntransition from massless to massive fermions, with the relativistic and\nnonrelativistic limits, via the tuning of controllable experimental parameters.",
