Generalized Families of QFTs
T. Daniel Brennan, Kenneth Intriligator
RG flows and IR phases of QFTs can be constrained by generalized symmetries and their anomalies. Broken symmetries act on the space of coupling constants of families of theories, a…
Monopole Catalyzed Baryogenesis with a angle
T. Daniel Brennan, Lian-Tao Wang, Huangyu Xiao
Monopoles are generally expected in Grand Unified Theories (GUTs) where they can catalyze baryon decay at an unsuppressed rate by the Callan-Rubakov effect. For the first time, we…
Anomalies of 4d Theories
T. Daniel Brennan, Kenneth Intriligator
We consider 't Hooft anomalies of four-dimensional gauge theories whose fermion matter content admits generalized spin structure, with either gauged or a global sym…
Anomaly Enforced Gaplessness for Background Flux Anomalies and Symmetry Fractionalization
T. Daniel Brennan, Aiden Sheckler
Anomalous symmetries are known to strongly constrain the possible IR behavior along any renormalization group (RG) flow. Recently, the extension of the notion of symmetry in QFT ha…
Index-Like Theorems from Line Defect Vevs
T. Daniel Brennan, Gregory W. Moore
In this paper we investigate the relation between complexified Fenchel-Nielsen coordinates and spectral network coordinates on Seiberg-Witten moduli space. The main technique is th…
't Hooft Defects and Wall Crossing in SQM
T. Daniel Brennan, Anindya Dey, Gregory W. Moore
In this paper we study the contribution of monopole bubbling to the expectation value of supersymmetric 't Hooft defects in Lagrangian theories of class on $\mathbb{R…
Wall Crossing from Dirac Zeromodes
T. Daniel Brennan, Gregory W. Moore, Andrew B. Royston
We explore the physics of two-body decay of BPS states using semiclassical analysis to construct explicit solutions that illustrate the main features of wall crossing, for both ord…
On 't Hooft Defects, Monopole Bubbling and Supersymmetric Quantum Mechanics
T. Daniel Brennan, Anindya Dey, Gregory W. Moore
We revisit the localization computation of the expectation values of 't Hooft operators in SU(N) theory on . We show that the part of the…
A Note On The Semiclassical Formulation Of BPS States In Four-Dimensional N=2 Theories
T. Daniel Brennan, Gregory W. Moore
Vector spaces of (framed) BPS states of Lagrangian four-dimensional N=2 field theories can be defined in semiclassical chambers in terms of the -cohomology of Dirac-like opera…
