More Exotic Field Theories in 3+1 Dimensions
Pranay Gorantla, Ho Tat Lam, Nathan Seiberg +1
We continue the exploration of nonstandard continuum field theories related to fractons in 3+1 dimensions. Our theories exhibit exotic global and gauge symmetries, defects with res…

Memories of initial states and density imbalance in dynamics of interacting disordered systems
Ahana Chakraborty, Pranay Gorantla, Rajdeep Sensarma
We study the dynamics of one and two dimensional disordered lattice bosons/fermions initialized to a Fock state with a pattern of and particles on and sites.…

Non-Equilibrium Field Theory for Dynamics Starting from Arbitrary Athermal Initial Conditions
Ahana Chakraborty, Pranay Gorantla, Rajdeep Sensarma
Schwinger Keldysh field theory is a widely used paradigm to study non-equilibrium dynamics of quantum many-body systems starting from a thermal state. We extend this formalism to d…
