Chiral Phases on the Lattice by DeMarco, Michael Austin

“…While chiral quantum field theories (QFTs) describe a wide range of physical systems, from the standard model to topological quantum matter, the realization of chiral QFTs on a lattice has proved to be difficult due to the Nielsen-Ninomiya theorem and the possible presence of quantum anomalies. …”

Chiral anomaly in Euler fluid and Beltrami flow by P. B. Wiegmann, A. G. Abanov

“…Abstract We show that barotropic flows of a perfect, charged, classical fluid exhibit an anomaly analogous to the chiral anomaly known in quantum field theories with Dirac fermions. A prominent effect of the chiral anomaly is the transport electric current in the fluid at equilibrium with the chiral reservoir. …”

A stringy effect on Hawking radiation by Pei-Ming Ho, Yosuke Imamura, Hikaru Kawai, Wei-Hsiang Shao

“…We study a class of quantum field theories that exhibit this feature modeled after Witten’s bosonic open string field theory, and discover a Lorentz-invariant UV/IR relation that leads to the spacetime uncertainty principle proposed by Yoneya. …”

Aspects of 4d supersymmetric dynamics and geometry by Shlomo S. Razamat, Evyatar Sabag, Orr Sela, Gabi Zafrir

“…In this set of five Lectures we present a basic toolbox to discuss the dynamics of four dimensional supersymmetric quantum field theories. In particular we overview the program of geometrically engineering the four dimensional supersymmetric models as compactifications of six dimensional SCFTs. …”

T T ¯ $$ T\overline{T} $$ deformed scattering happens within matrices by Vasudev Shyam, Yigit Yargic

“…Abstract We show the T T ¯ $$ T\overline{T} $$ deformation of two-dimensional quantum field theories is equivalent to replacing the spacetime dependence of the fields with dependence on the indices of infinitely large matrices. …”

Finite volume form factors in integrable theories by Zoltan Bajnok, Georgios Linardopoulos, Istvan M. Szecsenyi, Istvan Vona

“…Abstract We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these corrections from the excited state expectation value of bilocal operators in the limit when the operators are far apart. …”

Landau poles in condensed matter systems by Shao-Kai Jian, Edwin Barnes, Sankar Das Sarma

“…The existence or not of Landau poles is one of the oldest open questions in nonasymptotic quantum field theories. We investigate the Landau pole issue in two condensed matter systems whose long-wavelength physics is described by appropriate quantum field theories: the critical quantum magnet and Dirac fermions in graphene with long-range Coulomb interactions. …”
