Question
The Fakhri lab realized a “living chiral crystal” of starfish embryos displaying “odd dynamics,” which can be described theoretically as this type of matter. For 10 points each:
[10h] What adjective describes profoundly out-of-equilibrium systems that produce energy at the microscopic scale?
ANSWER: active matter
[10m] A hallmark of active matter is the loss of this symmetry, which is associated with the loss of detailed balance. When deriving the Onsager reciprocal relations, one interchanges labels by assuming this discrete symmetry, which is broken by magnetic fields.
ANSWER: time-reversal symmetry [or T symmetry; or TRS; accept descriptions of t goes to negative t; prompt on time; prompt on reversible or reversibility; reject “time translation symmetry”]
[10e] A loss of time reversal symmetry allows for the “odd” type of this quantity to be realized. This quantity relates the shear stress in a fluid to the flow velocity.
ANSWER: viscosity [accept odd viscosity; accept viscosity tensor]
