Phases of melonic quantum mechanics

F Ferrari, FI Schaposnik Massolo - Physical Review D, 2019 - APS
We explore in detail properties of two melonic quantum mechanical theories which can be
formulated either as fermionic matrix quantum mechanics in the new large D limit, or as …

Majorana fermion quantum mechanics for higher rank tensors

IR Klebanov, PN Pallegar, FK Popov - Physical Review D, 2019 - APS
We study quantum mechanical models in which the dynamical degrees of freedom are real
fermionic tensors of rank 5 and higher. They are the nonrandom counterparts of the Sachdev …

N = 0 , 2 SYK, chaos and higher-spins

C Peng - Journal of High Energy Physics, 2019 - repo.scoap3.org
We study a 2-dimensional SYK-like model with N=(0, 2) supersymmetry. The model
describes N chiral supermultiplets and M Fermi supermultiplets with a (q+ 1)-field …

Melonic dominance in subchromatic sextic tensor models

S Prakash, R Sinha - Physical Review D, 2020 - APS
We study tensor models based on O (N) r symmetry groups constructed out of rank-r tensors
with order-q interaction vertices. We refer to those tensor models for which r< q-1 as …

Exact Solution of a Strongly Coupled Gauge Theory in Dimensions

C Krishnan, KVP Kumar - Physical Review Letters, 2018 - APS
Gauged tensor models are a class of strongly coupled quantum mechanical theories. We
present the exact analytic solution of a specific example of such a theory: namely, the …

Quantum resonant systems, integrable and chaotic

O Evnin, W Piensuk - Journal of Physics A: Mathematical and …, 2018 - iopscience.iop.org
Resonant systems emerge as weakly nonlinear approximations to problems with highly
resonant linearized perturbations. Examples include nonlinear Schrödinger equations in …

Near conformal perturbation theory in SYK type models

SR Das, A Ghosh, A Jevicki, K Suzuki - Journal of High Energy Physics, 2020 - Springer
A bstract We present a systematic procedure to extract the dynamics of the low energy soft

Large- phase transition in a finite lattice gauge theory

N Brahma, C Krishnan - Physical Review D, 2021 - APS
We consider gauge theories of non-Abelian finite groups, and discuss the 1+ 1 dimensional

Superconducting gap ratio from strange metal phase in the absence of quasiparticles

W Cai, XH Ge - Communications in Theoretical Physics, 2021 - iopscience.iop.org
A lattice model for strongly interacting electrons motivated by a rank-3 tensor model provides
a tool for understanding the pairing mechanism of high-temperature superconductivity. This …
