Charge acceleration without radiation
Yakir Aharonov, Daniel Collins, Sandu Popescu
The existence of electromagnetic radiation - radio-waves, microwaves, light, x-rays and so on - is one of the most important physical phenomena, and our ability to manipulate them…
Conservation Laws For Every Quantum Measurement Outcome
Daniel Collins, Sandu Popescu
In the paradigmatic example of quantum measurements, whenever one measures a system which starts in a superposition of two states of a conserved quantity, it jumps to one of the tw…
Conservation laws and the foundations of quantum mechanics
Yakir Aharonov, Sandu Popescu, Daniel Rohrlich
In a recent paper, PNAS, 118, e1921529118 (2021), it was argued that while the standard definition of conservation laws in quantum mechanics, which is of a statistical character, i…
Angular Momentum Flows without anything carrying it
Yakir Aharonov, Daniel Collins, Sandu Popescu
Transfer of conserved quantities between two remote regions is generally assumed to be a rather trivial process: a flux of particles carrying the conserved quantities propagates fr…
