They host Weyl nodes at specific po ints in their Brillouin zone\, a pair of relativistic fermions with diffe rent chirality\, Weyl fermions. The nontrivial momentum-space topology du e to the Weyl nodes leads to various fascinating phenomena\, such as the chiral anomaly\, chiral magnetic effect\, anomalous magnetoresistance and Hall effect\, large nonsaturating thermoelectric power and ultrafast pho tocurrents just to name a few. The essential ingredients for the realizat ion of the Weyl semimetal are the absence of inversion symmetry and/or ti me-reversal symmetry. The RAlX (where R=Rare Earth and X=Ge\, Si) family\ , where both symmetries are broken\, has been recently identified as a la rge class of Weyl semimetal based on systematic first-principles band str ucture calculations and APRES measurements. In this respect\, I will pres ent details and importance of crystal growth of non-centrosymmetric CeAlG e single crystals\, their physical properties\, anomalous magnetotranspor t\, and discuss the future implications of our findings and the tunabilit y of RAlGe and RAlSi families.\n\n\nThis is a Zoom seminar: https://misso uristate.zoom.us/s/95408107110 X-ALT-DESC;FMTTYPE=text/html:<html><head><title></title></head><body><p><b >Dr. Halya Hodovanets</b><br><b>Missouri University of Science &amp\;Tech nology</b></p>\n<p>Abstract:<br>Weyl semimetals are among the materials p roposed to have significant potential in informational technologies and t o harbor the necessary elements for quantum computing.
