3 Majorana Fermion a particle that is equal to its own anti-particle γ = γ creating a Majorana is the same operation as annihilating it: meaning zero energy, zero spin and zero charge. okay for Bosons but not for Fermions (electron positron) How to detect a particle with everything zero? 1938 (Wilczek, Majorana Returns, Nature Physics, 2009 Wilczek, Majorana modes materialize, Nature, News&Views, 2012)

5 ParKcle superposikons equal superposition of an electron and a hole c = c = c = γ 1 + iγ 2 creates an electron c = γ 1 - iγ 2 creates a hole γ 1 = ½ (c + c) is Majorana-1 γ 2 = ½i (c - c) is Majorana-2 satisfying γ 1 = γ 1 and γ 2 = γ 2 One Majorana is half a Fermion

46 Conclusions
47 Majorana recipe 1. One-dimensional quantum wire 2. Spin-orbit interaction 3. Superconductivity 4. Apply magnetic field (Lutchyn, Sau, Das Sarma, PRL 2010, Oreg, Refael, von Oppen, PRL 2010) Unique recipe for Majoranas. Take one ingredient out and Majoranas are gone. ZBP rigid over large ranges in B and Vg.
48 Theories are excluded that are based on: - an efffect from the tunnel barrier - T ~ 1 => no Coulomb blockade - ballistic wires => no localization effects - Kondo only possible if g < 0.5 = g InSb /100
49 BARRIER
50 Fermi level Sharp barrier 1. With a sharp tunnel barrier, only the top populated subband will be topological (holds Majorana s) and the other two bands as shown in the plot are all trivial. 2. As the tunnel barrier is sharp, the three bands have the same transmmision coefficient, therefore Majorana s as ZBP in the tunneling measurement will be clear. Dashed lines indicate the spin orbit gap
51 Fermi level Sharp barrier If we have a smooth barrier, the situakon would be different 1. For smooth barrier, what is the relevant length scale? 2. What are the coherence length of Majorana s, could we have mulkple Majorana s, like indicated in the figure. Dashed lines indicate the spin orbit gap
52 Fermi level An more exaggerated case, tunnel barrier is very smooth, could be relevant for T. Stanescu s soi gap paper, the two more possible Majorana s pairs are well separated (skll depend on the coherent length of Majorana s in the system): 1. Could we discriminate them? 2. What is the visibility difference in tunneling measurements of the Majorana s at the top subband vs. lower subbands? 3. How about the stability in B and chemical potenkal of these Majorana s at lower subbands compared to top subband Majorana s? Dashed lines indicate the spin orbit gap
