<html>
<p>Today I decided to submit a post, and after few hours of work, I had a little surprise. When I clicked on the post button, it showed up an error: <em><strong>Missing posting key the-future</strong></em></p>
<p>The point is that I used my posting key only once, so it was hard for me to lose it (:D little joke). What I have done?!</p>
<p>I backup the post text into a text editor, refresh the page, and try again but no luck. Then I log out and log in back again, I arranged the post again and pushed the post button (surprise number two)- the same error. I repeated this process few times but without luck. I'm not a coder or that kind of person, so I decided to ask for help at the steemit chat.</p>

<p>I have told to @pfunk about it because I knew he knows much more about this stuff than I know, and he was very helpful. He wasn't the only one who tried to help me, there were also @liondani and @gandalf.</p>
<p>Let's take a look:</p>
<p> @pfunk</p>
<blockquote>It's possible some odd characters/spaces in the title or tag fields are causing trouble. Make sure there aren't any preceding spaces in them, or extra spaces in tags</blockquote>
<p>@liondani</p>
<blockquote> Sign out and sign in again with your posting key? </blockquote>
<p>@gandalf</p>
<blockquote>I thought that it was already fixed but some time ago (like weeks if not months) there was some issues like this but it was not related to keys at all, errors came out because of some special characters within post that was not parsed correctly, etc. </blockquote>
<p>I placed all the pieces in the puzzle and it worked. Here is what I think it was the problem.</p>
<p>I tooked some photos with the characters that I think were the problem, and <em><strong>below on each photo</strong></em>, you will find a link where you will be able to copy those characters. <em><strong>I couldn't copy and paste here remember?</strong></em> I don't like those kind of surprises!</p>

<p>FIG. 1: Floquet evolution of a spin chain. Three Hamiltonians are applied sequentially in time: a global spin flip of nearly (H1), long-range Ising interactions (H2), and strong disorder (H3). The system evolves for 100 Floquet periods of this sequence.</p>

<p>FIG. 2: Spontaneous breaking of discrete time translation symmetry. Top panel: Time-evolved magnetizations of</p>
<p>each spin hxi (t)i and their Fourier spectra, showing sub-harmonic response of the system to the Floquet Hamiltonian. (a)When only the H1 spin flip is applied, the spins oscillate with a sub-harmonic response that beats due to the perturbation" = 0:03 from perfect -pulses, with a clear splitting in the Fourier spectrum. (b) With both the H1 spin flip and the disorder H3, the spins precess with various Larmor rates in the presence of di erent individual elds. (c) Finally, adding the spin-spin interaction term H2 (shown with the largest interaction phase J0t2 = 0:036 rad), the spins lock to the sub-harmonic frequency of the drive period. Here the Fourier spectrum merges into a single peak even in the face of perturbation " on the spin flip H1. (d) When the perturbation is too strong (" = 0:11), we cross the boundary from the discrete time crystal into a symmetry unbroken phase10. Bottom panel: Individually resolved time traces. (e) Spin magnetization for all 10 spins corresponding to the case of (b). (f) Spin 3 and 8 corresponding to the case of (c). Each point is the average of 150 experimental repetitions. Error bars are computed from quantum projection noise and detection in delities.</p>

<p>FIG. 1: Experimental setup and sequence for observing time-crystalline order. a, NV centers in a nanobeam fabricated from black diamond are illuminated by a focused green laser beam and irradiated by a microwave source.Within one Floquet cycle, the spins evolve under a dipolar interaction for duration 1, followed by a global spin rotation acting for duration 2. Experimental sequence: spins are prepared in the (jms = 0i + jms = ๔1i)=p2 state using a microwave (๔=2)-pulse along the ^y axis. Subsequently,the spins evolve for 1 under a strong microwave eld aligned along the ^x axis, immediately followed by a strong microwave-pulse along the ^y axis. After n repetitions of the Floquet cycle, the spin polarization is read out by applying another microwave (=2)-pulse along the ^y axis. b-d, Representative time traces of the spin polarization P(nT) and respective</p>
