David Campbell

About

David Campbell is a Professor of Physics, Electrical and Computer Engineering (ECE), and Materials Science and Engineering (MSE) at Boston University, serving as the Director of Graduate Studies. His research interests encompass correlated electronic systems, nonlinear excitations, and non-equilibrium phenomena. He has investigated correlated electronic systems in reduced spatial dimensions, including conducting polymers, superconducting organic charge transfer salts, graphene, and other two-dimensional electronic membranes, often employing a version of the functional Renormalization Group (fRG) that he developed with colleagues. Campbell has a long-standing interest in solitons and nonlinear excitations, studying intrinsic localized modes (ILMs) in solids and Bose-Einstein Condensates (BECs) trapped in optical lattices. Additionally, he explores non-equilibrium problems, particularly the metastable states in Fermi-Pasta-Ulam-Tsingou (FPUT) simulations, which delay or prevent the approach to thermodynamic equilibrium. His contributions have significantly advanced understanding in these areas, supported by numerous publications and recognition through prestigious awards and fellowships.

• Self-expanding Transcatheter vs Surgical Aortic Valve Replacement in Intermediate-Risk Patients

  JAMA Cardiology · 2022 · 169 citations

  Importance: In patients with severe aortic valve stenosis at intermediate surgical risk, transcatheter aortic valve replacement (TAVR) with a self-expanding supra-annular valve was noninferior to surgery for all-cause mortality or disabling stroke at 2 years. Comparisons of longer-term clinical and hemodynamic outcomes in these patients are limited. Objective: To report prespecified secondary 5-year outcomes from the Symptomatic Aortic Stenosis in Intermediate Risk Subjects Who Need Aortic Valve…

• Adiabatic Eigenstate Deformations as a Sensitive Probe for Quantum Chaos

  Physical Review X · 2020 · 138 citations

  In the past decades, it was recognized that quantum chaos, which is essential for the emergence of statistical mechanics and thermodynamics, manifests itself in the effective description of the eigenstates of chaotic Hamiltonians through random matrix ensembles and the eigenstate thermalization hypothesis. Standard measures of chaos in quantum many-body systems are level statistics and the spectral form factor. In this work, we show that the norm of the adiabatic gauge potential, the generator o…

• Bempegaldesleukin Plus Nivolumab Versus Sunitinib or Cabozantinib in Previously Untreated Advanced Clear Cell Renal Cell Carcinoma: A Phase III Randomized Study (PIVOT-09)

  Journal of Clinical Oncology · 2024-06-05 · 23 citations

  article

  PURPOSE Bempegaldesleukin (BEMPEG) is a pegylated interleukin (IL)-2 cytokine prodrug engineered to provide controlled and sustained activation of the clinically validated IL-2 pathway, with the goal of preferentially activating and expanding effector CD8 + T cells and natural killer cells over immunosuppressive regulator T cells in the tumor microenvironment. The open-label, phase III randomized controlled PIVOT-09 trial investigated the efficacy and safety of BEMPEG plus nivolumab (NIVO) as fi…
