 abstract = {We study the static and dynamical properties of a long-range Kitaev
chain, i.e. a p-wave superconducting chain in which the superconducting
pairing decays algebraically as 1/l(alpha), where l is the distance
between the two sites and alpha is a positive constant. Considering very
large system sizes, we show that when alpha > 1, the system is
topologically equivalent to the short-range Kitaev chain with massless
Majorana modes at the ends of the system; on the contrary, for alpha <
1, there exist symmetry protected massive Dirac end modes. We further
study the dynamical phase boundary of the model when periodic
delta-function kicks are applied to the chemical potential; we specially
focus on the case alpha > 1 and analyze the corresponding Floquet
quasienergies. Interestingly, we find that new topologically protected
massless end modes are generated at the quasienergy pi/T (where T is the
time period of driving) in addition to the end modes at zero energies
which exist in the static case. By varying the frequency of kicking, we
can produce topological phase transitions between different dynamical
phases. Finally, we propose some bulk topological invariants which
correctly predict the number of massless end modes at quasienergies
equal to 0 and pi/T for a periodically kicked system with alpha > 1.},
