Picosecond volume expansion drives a later-time insulator-metal transition in a nano-textured Mott Insulator
Anita Verma, Denis Golež, Oleg Yu. Gorobtsov +24
Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrins…
Large Itinerant Electron Exchange Coupling in the Magnetic Topological Insulator MnBi2Te4
Hari Padmanabhan, Vladimir A. Stoica, Peter Kim +20
Magnetism in topological materials creates phases exhibiting quantized transport phenomena with applications in spintronics and quantum information. The emergence of such phases re…
Interlayer magnetophononic coupling in MnBi2Te4
Hari Padmanabhan, Maxwell Poore, Peter Kim +16
The emergence of magnetism in quantum materials creates a platform to realize spin-based applications in spintronics, magnetic memory, and quantum information science. A key to unl…
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…
Spatio-temporal Symmetry - Point Groups with Time Translations
Haricharan Padmanabhan, Maggie L. Kingsland, Jason M. Munro +2
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 F…
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…
