As Boston University's largest academic division, the College and Graduate School of Arts & Sciences is the heart of the BU experience. Undergraduates choose from more than 2,500 courses in the humanities, natural and social sciences, and mathematics and computer science and pursue BA programs in more than 70 concentrations. Graduate students can earn an MA or PhD in nearly 50 fields of the humanities; the natural, social, and mathematical sciences; theology; and music. A robust and productive learning environment awaits everyone who enrolls here.

  • Dataset for: Mother-offspring proximity maintenance as an infanticide avoidance strategy in Bornean orangutans 

    Scott, Amy; Knott, Cheryl; Mitra Setia, Tatang; Susanto, Tri Wahyu (2022-05-19)
  • Attack of the clones: microglia in health and disease 

    Manjally, Amritha Vinayak; Tay, Tuan Leng (2022)
    [INTRODUCTION] Microglia are brain-resident macrophages that carry out immune surveillance, support neurogenesis and neuronal survival, shape the neuronal network, and maintain tissue homeostasis (Nimmerjahn et al., 2005; ...
  • Fractional and composite excitations of antiferromagnetic quantum spin trimer chains 

    Cheng, Jun-Qing; Li, Jun; Xiong, Zijian; Wu, Han-Qing; Sandvik, Anders W.; Yao, Dao-Xin (Springer Science and Business Media LLC, 2022-12)
    Using quantum Monte Carlo, exact diagonalization, and perturbation theory, we study the spectrum of the S = 1/2 antiferromagnetic Heisenberg trimer chain by varying the ratio g = J2/J1 of the intertrimer and intratrimer ...
  • Temperature dependence of the (π,0) anomaly in the excitation spectrum of the 2D quantum Heisenberg antiferromagnet 

    Wan, W.; Christensen, N.B.; Sandvik, Anders W.; Tregenna-Piggott, P.; Nilsen, G.J.; Mourigal, M.; Perring, T.G.; Frost, C.D.; McMorrow, D.F.; Rønnow, H.M. (Institute of Physics, 2019)
    It is well established that in the low-temperature limit, the two-dimensional quantum Heisenberg antiferromagnet on a square lattice (2DQHAFSL) exhibits an anomaly in its spectrum at short-wavelengths on the zone-boundary. ...
  • Introduction to lightcone conformal truncation: QFT dynamics from CFT data 

    Anand, Nikhil; Fitzpatrick, A. Liam; Katz, Emanuel; Khandker, Zuhair U.; Walters, Matthew T.; Xin, Yuan (2020-05-27)
    We both review and augment the lightcone conformal truncation (LCT) method. LCT is a Hamiltonian truncation method for calculating dynamical quantities in QFT in infinite volume. This document is a self-contained, pedagogical ...
  • Model-dependence of minimal-twist OPEs in d > 2 holographic CFTs 

    Fitzpatrick, A. Liam; Huang, Kuo-Wei; Meltzer, David; Perlmutter, Eric; Simmons-Duffin, David (Springer Science and Business Media LLC, 2020-11)
    Following recent work on heavy-light correlators in higher-dimensional conformal field theories (CFTs) with a large central charge CT, we clarify the properties of stress tensor composite primary operators of minimal twist, ...
  • Solving the 2D SUSY Gross-Neveu-Yukawa Model with Conformal Truncation 

    Fitzpatrick, A. Liam; Katz, Emanuel; Walters, Matthew T.; Xin, Yuan (Springer Verlag (Germany), 2021-01-27)
    We use Lightcone Conformal Truncation to analyze the RG flow of the two-dimensional supersymmetric Gross-Neveu-Yukawa theory, i.e. the theory of a real scalar superfield with a $\mathbb{Z}_2$-symmetric cubic superpotential. ...
  • The most irrational rational theories 

    Benjamin, Nathan; Dyer, Ethan; Fitzpatrick, A. Liam; Xin, Yuan (Springer Science and Business Media LLC, 2019-04)
    We propose a two-parameter family of modular invariant partition functions of two-dimensional conformal field theories (CFTs) holographically dual to pure three-dimensional gravity in anti de Sitter space. Our two parameters ...
  • Probing universalities in d > 2 CFTs: from black holes to shockwaves 

    Fitzpatrick, A. Liam; Huang, Kuo-Wei; Li, Daliang (Springer Science and Business Media LLC, 2019-11)
    Gravitational shockwaves are insensitive to higher-curvature corrections in the action. Recent work found that the OPE coefficients of lowest-twist multi-stress-tensor operators, computed holographically in a planar black ...
  • Nonperturbative matching between equal-time and lightcone quantization 

    Fitzpatrick, A. Liam; Katz, Emanuel; Walters, Matthew T. (Springer Science and Business Media LLC, 2020-10)
    We investigate the nonperturbative relation between lightcone (LC) and standard equal-time (ET) quantization in the context of λϕ4 theory in d = 2. We discuss the perturbative matching between bare parameters and the failure ...
