I Quantum Hall Effect and Hall Voltage

I understand that the Quantum Hall Effect explains how both the transverse and longitudinal resistance vary with magnetic field strength.

I don’t get why the hall resistance is equal to the hall voltage over the current .


I know current isn’t a vector quantity but isn’t the hall resistance an opposition to the charge flow that goes across the conductor due to the magnetic field?

I have read that Ohm’s Law has nothing to do with Hall Voltage but I can’t understand why Rhall=Vhall/I

I would only think the longitudinal resistance would be an opposition to the current I.

What is wrong with the way I am visualizing this?
 

Thread 'Prof Mike Wiest's proposed link between quantum and consciousness'

I am not sure if this belongs in the biology section, but it appears more of a quantum physics question. Mike Wiest, Associate Professor of Neuroscience at Wellesley College in the US. In 2024 he published the results of an experiment on anaesthesia which purported to point to a role of quantum processes in consciousness; here is a popular exposition: https://neurosciencenews.com/quantum-process-consciousness-27624/ As my expertise in neuroscience doesn't reach up to an ant's ear...

Thread 'Is It Known For Sure Infinites In QFT Are Caused Using a Continuum?'

I am reading WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians. The author states (2.4 Finite versus Continuous Models) that the use of continuity causes the infinities in QFT: 'Mathematicians are trained to think of physical space as R3. But our continuous model of physical space as R3 is of course an idealization, both at the scale of the very large and at the scale of the very small. This idealization has proved to be very powerful, but in the case of Quantum...
