Direct observation of symmetry-breaking in a 'ferroelectric' polar metal
Emma Berger, Sasawat Jamnuch, Can Uzundal +17
Ferroelectric materials contain a switchable spontaneous polarization that persists even in the absence of an external electric field. The coexistence of ferroelectricity and metal…
Antisymmetry: Fundamentals and Applications
Hari Padmanabhan, Jason M. Munro, Ismaila Dabo +1
Symmetry is fundamental to understanding our physical world. An antisymmetry operation switches between two different states of a trait, such as two time-states, position-states, c…
Linear and nonlinear optical probe of the ferroelectric-like phase transition in a polar metal, LiOsO3
Haricharan Padmanabhan, Yoonsang Park, Danilo Puggioni +7
LiOsO3 is one of the first materials identified in a recent literature as a 'polar metal', a class of materials that are simultaneously noncentrosymmetric and metallic. In this wor…
A new symmetry-based framework for discovering minimum energy pathways
Jason M. Munro, Hirofumi Akamatsu, Haricharan Padmanabhan +6
Physical systems evolve from one state to another along paths of least energy barrier. Without a priori knowledge of the energy landscape, multidimensional search methods aim to fi…
Intertwined Lattice Deformation and Magnetism in Monovacancy Graphene
Haricharan Padmanabhan, B. R. K. Nanda
Using density functional calculations we have investigated the local spin moment formation and lattice deformation in graphene when an isolated vacancy is created. We predict two c…
