Magnetism and Peierls distortion in Dirac semimetal CaMnBi
Aashish Sapkota, Niraj Aryal, Xiao Hu +9
Dirac semimetals of the form Mn ( alkaline-earth or divalent rare earth; Bi, Sb) host conducting square-net Dirac-electron layers of atoms interleaved with a…
Large non-saturating Nernst thermopower and magnetoresistance in compensated semimetal ScSb
Antu Laha, Sarah Paone, Niraj Aryal +1
Today, high-performance thermoelectric and thermomagnetic materials operating in the low-temperature regime, particularly below the boiling point of liquid nitrogen remain scarce.…
Single crystalline orthorhombic GdAlGe as a rare earth magnetic Dirac nodal-line metal
Antu Laha, Juntao Yao, Asish K. Kundu +11
Crystal engineering is a method for discovering new quantum materials and phases, which may be achieved by external pressure or strain. Chemical pressure is unique in that it gener…
Nernst power factor and figure of merit in compensated semimetal ScSb
Antu Laha, Sarah Paone, Asish K. Kundu +4
Recently, topological semimetals have emerged as strong candidates for solid state thermomagnetic refrigerators due to their enhanced Nernst effect. This enhancement arises from th…
Machine learning approach for vibronically renormalized electronic band structures
Niraj Aryal, Sheng Zhang, Weiguo Yin +1
We present a machine learning (ML) method for efficient computation of vibrational thermal expectation values of physical properties from first principles. Our approach is based on…
