Solvable Models of Heat Transport in Quantum Mechanics
R Loganayagam, Prithvi Narayan, Swathi T S
We investigate solvable models of heat transport between a pair of quantum mechanical systems initialized at two different temperatures. At time , a weak interaction is switch…
Gravitational Edge Mode in Asymptotically AdS: JT Gravity Revisited
Euihun Joung, Prithvi Narayan, Junggi Yoon
We study the gravitational edge mode of the Jackiw-Teitelboim (JT) gravity and its BF theory description with the asymptotic AdS boundary condition. We revis…
SYK Model with global symmetries in the double scaling limit
Prithvi Narayan, Swathi T S
We discuss the double scaling limit of the SYK model with global symmetries. We develop the chord diagram techniques to compute the moments of the Hamiltonian and the two point fun…
Estimating entanglement in 2D Heisenberg model in the strong rung-coupling limit
Chandrima B. Pushpan, Harikrishnan K. J., Prithvi Narayan +1
In this paper, we calculate entanglement in the isotropic Heisenberg model in a magnetic field on a two-dimensional rectangular zig-zag lattice in the strong rung-coupling limit, u…
Quantum groups, non-commutative , and chords in the double-scaled SYK model
Micha Berkooz, Mikhail Isachenkov, Prithvi Narayan +1
We study the double-scaling limit of SYK (DS-SYK) model and elucidate the underlying quantum group symmetry. The DS-SYK model is characterized by a parameter , and in the $q\rig…
Exactly Solvable 1D Quantum Models with Gamma Matrices
Yash Chugh, Kusum Dhochak, Uma Divakaran +2
In this paper, we write exactly solvable generalizations of 1-dimensional quantum XY and Ising-like models by using -dimensional Gamma () matrices as the degrees of freedom…
