                    Albanova colloquium: “Chiral critical matter"


                                          Prof. Leo Radzihovsky

                                             (University of Colorado at Boulder)



Liquid crystals are fascinating materials - quintessential condensed

matter exhibiting an array of complex phases of fundamental scientific

interest and at the heart of liquid crystal display revolution. I will

take the audience on a bit of a roller coaster ride, pedagogically

discussing a recently discovered exotic liquid crystal state, the

"heliconical nematic", that exhibits a long sought-after spontaneous

chiral symmetry breaking. I will also explain how low-energy physics of

some states of matter can be understood as an emergent Higgs mechanism,

with critical fluctuations extending throughout the low-temperature

"critical phase”.
