Tunneling times in quantum mechanics (English)
Abstract [sv]

Det råder idag inget konsensus om tiden som kvanttunnling tar. Den här rapporten har som syfte att undersöka tidigare arbete inom ämnet för att finna passande kandidater till tunnlingstiden. Simuleringar utförs för en endimensionell rektangulär potentialbarriär och används för att stödja existerande teoretiska tunnlingstider. Slutsatsen dras att tunnlingstiden inte beror på potentialbarriärens bredd och att tunnlingen därför kan ske med godtyckligt hög hastighet. Detta stödjer påståenden om att partiklar kan färdas snabbare än ljuset inom icke-relativistisk kvantmekanik.

Abstract [en]

There is no clear consensus for time that it takes for quantum tunneling to occur. This report aims to examine previous work in the field and find likely candidates for the tunneling time. Simulations are conducted on a one-dimensional rectangular barrier and used to verify previously postulated theoretical tunneling times. It is concluded that quantum tunneling time does not depend on the barrier width and tunneling thus can occur at arbitrarily high speed. This validates previous claims that particles can tunnel faster than light within the frames of non-relativistic quantum mechanics.
