We point out that if a certain variant of Quirks, particles that carry ordinary color and some other color exist, then we can have a completely novel and efficient mode of long distance communications and of acceleration to very high energies. For very low scale $Lambda$ the scale of the new gauge group in the theory, and associated string tension of the new color the Quirks can be captured in ordinary materials. Having then the Quirk Q and anti-Quirk $bar{Q}$ in two separate piezoelectric crystals at arbitrarily far out points A and B allows Alice and Bob at these locations to communicate by generating transverse waves along the connecting color string. Also releasing the Quirks allows them to collide at extremely high energies.
In the present paper, assuming the Multiple Point Principle (MPP) as a new law of Nature, we considered the existence of the two degenerate vacua of the Universe: a) the first Electroweak (EW) vacuum at $v_1approx 246$ GeV -- true vacuum, and b) the
We develop techniques to compute the one-loop anomalous dimensions of operators in the ${cal N}=4$ super Yang-Mills theory that are dual to open strings ending on boundstates of sphere giant gravitons. Our results, which are applicable to excitations
We consider magnetic monopoles and strings that appear in non-supersymmetric $SO(10)$ and $E_6$ grand unified models paying attention to gauge coupling unification and proton decay in a variety of symmetry breaking schemes. The dimensionless string t
We employ a variety of symmetry breaking patterns in $SO(10)$ and $E_6$ Grand Unified Theories to demonstrate the appearance of topological defects including magnetic monopoles, strings, and necklaces. We show that independent of the symmetry breakin
We present a new auxiliary field representation for the four-fermi term of the gauge-fixed Green-Schwarz superstring action which describes fluctuations around the null-cusp background in $AdS_5times S^5$. We sketch the main features of the fermionic
