Hello everyone,
This is a follow-up to the CQI seminar email earlier today for the mini-talk "Musings
on the space of Hamiltonians". Since this informal talk was announced (and planned)
at the last minute, several people couldn't come, so we've rescheduled it to next
Wednesday, 26 April, at 14:30 in D5.01. I've included a short title and abstract
below.
As always you can join us online at https://meet.jit.si/cqi-demon-M6QW9V7YY.
Warmly,
Will
Speaker: Will Schober (that's me)
Title: "Musings on the space of Hamiltonians" or, "Global phases are a
monkey wrench in the works"
Abstract: Most eligible Hamiltonians are not needed to completely describe quantum
dynamics; a bounded subset of the Hermitian matrices is sufficient to generate the unitary
group. I advocate removing the rest. The identification of global phases for state vectors
induces a further reduction of the necessary Hamiltonians. Some strange geometry arises as
a result.
