Linear and nonlinear optical probe of the ferroelectric-like phase transition in a polar metal, LiOsO3

Autor: Padmanabhan, Haricharan, Park, Yoonsang, Puggioni, Danilo, Yuan, Yakun, Cao, Yanwei, Gasparov, Lev, Shi, Youguo, Chakhalian, Jak, Rondinelli, James M., Gopalan, Venkatraman

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 work, the linear and nonlinear optical susceptibility of LiOsO3 is studie

Report

A new symmetry-based framework for discovering minimum energy pathways

Autor: Munro, Jason M., Akamatsu, Hirofumi, Padmanabhan, Haricharan, Liu, Vincent S., Shi, Yin, Chen, Long-Qing, VanLeeuwen, Brian K., Dabo, Ismaila, Gopalan, Venkatraman

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 find such minimum energy pathways between the initial and final states o

Spatio-temporal Symmetry - Point Groups with Time Translations

Autor: Padmanabhan, Haricharan, Kingsland, Maggie L., Munro, Jason M., Litvin, Daniel B., Gopalan, Venkatraman

Publikováno v: Symmetry 2017, 9(9), 187

Spatial symmetries occur in combination with temporal symmetries in a wide range of physical systems in nature, including time-periodic quantum systems typically described by the Floquet formalism. In this context, groups formed by three-dimensional

Intertwined Lattice Deformation and Magnetism in Monovacancy Graphene

Autor: Padmanabhan, Haricharan, Nanda, B. R. K.

Publikováno v: Phys. Rev. B 93, 165403 (2016)

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 competing equilibrium structures: a ground state planar configuration w

International audience; Hybrid improper ferroelectricity, which utilizes nonpolar but ubiquitous rotational/tilting distortions to create polarization, offers an attractive route to the discovery of new ferroelectric and multiferroic materials becaus
