The quantum field vacuum is altered by the passage of a uniformly moving charge, leaving in its wake a different dressed ground state. In this sense a charged particle leaves its electromagnetic scent even after passing by. Unlike in classical electrodynamics the effect of the charge remains even at infinite time. The calculation is done in detail for the ground state of a spacetime wedge, although the results are more general. This agrees in spirit with recent results over the infrared aspects of field theory, although the technical details are different. These considerations open the possibility that the information carried by quantum fields, being nonlocal, does not disappear beyond the horizon of black holes. 000070935 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MDM-2014-0369$$9info:eu-repo/grantAgreement/ES/MINECO/FPA2015-65745-P$$9info:eu-repo/grantAgreement/ES/DGA-FSE/E24-2$$9info:eu-repo/grantAgreement/EUR/COST/QSPACE 000070935 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000070935 590__ $$a5.833$$b2018 000070935 591__ $$aPHYSICS, PARTICLES & FIELDS$$b4 / 29 = 0.138$$c2018$$dQ1$$eT1 000070935 592__ $$a1.016$$b2018 000070935 593__ $$aNuclear and High Energy Physics$$c2018$$dQ1 000070935 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000070935 700__ $$aBalachandran, A.P. 000070935 700__ $$aLizzi, F. 000070935 700__ $$aMarmo, G. 000070935 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
