E. Dagotto is a physicist known for pioneering numerical and theoretical studies of strongly correlated electron systems, high-temperature superconductivity, and complex oxides. His work bridges computational methods and experimental phenomena in materials such as cuprates, manganites, and iron-based superconductors, and he has held positions in leading research universities and national laboratories. Dagotto's publications and collaborations span topics including the Hubbard model, t-J model, phase separation, and nanoscale inhomogeneity in correlated materials.
Dagotto obtained his undergraduate and graduate training in physics at institutions that include University of São Paulo and University of Campinas before completing advanced studies at Cornell University. During his formative years he engaged with topics related to many-body theory, lattice models, and numerical techniques that are central to research on the Hubbard model, t-J model, and quantum magnetism. His mentors and collaborators have included researchers associated with Los Alamos National Laboratory, Bell Labs, and academic groups at Universidade Estadual de Campinas.
Dagotto has held faculty appointments and research positions at the University of Tennessee and affiliated roles at Oak Ridge National Laboratory. He has collaborated with scientists at the National High Magnetic Field Laboratory, Argonne National Laboratory, and international centers such as Max Planck Institute for Solid State Research and École Polytechnique. His career includes visiting scholar posts and lecture series at institutions like Massachusetts Institute of Technology, Stanford University, Harvard University, and Princeton University.
Dagotto's research advanced numerical approaches for correlated electrons, applying techniques such as exact diagonalization, density matrix renormalization group (DMRG), and Monte Carlo methods to problems in high-temperature superconductivity and oxide materials. He produced influential studies on the microscopic behavior of cuprate superconductors, proposing roles for stripe order, phase separation, and nanoscale inhomogeneity in La2-xSrxCuO4 and related compounds. His group explored colossal magnetoresistance in manganites such as La1-xCaxMnO3, elucidating competition between ferromagnetism and charge/orbital order and connections to percolative transport. Dagotto contributed theoretical insight into pairing mechanisms in iron-based superconductors, multiferroic behavior in BiFeO3, and emergent phenomena in transition metal oxides. He linked model Hamiltonian results to spectroscopies conducted at facilities such as Brookhaven National Laboratory, Argonne National Laboratory, and the European Synchrotron Radiation Facility.
Dagotto has received awards and recognition from professional societies and national agencies, including honors associated with the American Physical Society, research fellowships connected to National Science Foundation programs, and distinctions from university research offices. His work has been cited in reviews published by journals such as Reviews of Modern Physics and he has been invited to deliver named lectures at venues like International Conference on Strongly Correlated Electron Systems and meetings organized by the Materials Research Society.
Dagotto authored and coauthored highly cited papers and reviews addressing computational methods and correlated materials, appearing in journals including Physical Review Letters, Physical Review B, Nature Materials, and Science. Notable works treat the Hubbard model, stripe phases in cuprates, and theoretical modeling of manganites and multiferroics, often with collaborators from University of California, Berkeley, Columbia University, University of Geneva, and University of Tokyo.
As a professor and mentor, Dagotto supervised graduate students and postdoctoral researchers who proceeded to positions at institutions like University of California, Los Angeles, Yale University, University of Cambridge, University of Oxford, and national laboratories including Lawrence Berkeley National Laboratory. He taught courses on quantum many-body physics, computational physics, and condensed matter theory, contributing to curricula referenced by programs at ETH Zurich, Imperial College London, and Tokyo Institute of Technology.
Dagotto has served on program committees and advisory boards for conferences such as the APS March Meeting, MRS Fall Meeting, and international workshops on correlated electrons. He has reviewed proposals for agencies including the Department of Energy and the European Research Council, and organized symposia at venues like Gordon Research Conferences and the International Conference on Strongly Correlated Electron Systems. Outreach activities include public lectures and media interviews about superconductivity and materials research at institutions including Smithsonian Institution events and university public forums.
