Stability against the odds: the case of chromonic liquid crystals

HIGHLIGHTS

• who: Silvia Paparini from the securing a solution to the variational problem in an admissible class of distortions with cylindrical symmetryThe issue about the stability of such a solution then remained open, a question that was not idle to ask, given the wildness of the parent energy. To resolve this issue, we derived a general formula for the second variation of Frank's elastic free-energy functional and applied it to the study of the (local) stability of the twisted ground state of chromonics. We concluded that this is stable. The role played by boundary conditions in . . .
