Quantum models with the Yang-Lee phase transition
Erick Arguello Cruz, Grigory Tarnopolsky
In this article, we present four different D quantum models that realize the Yang-Lee (YL) phase transition under a deformation that preserves symmetry. These are the ant…
Four-point function of the complex Sachdev-Ye-Kitaev model at finite chemical potential
Can Onur Akyuz, Erick Arguello Cruz, Ludo Fraser-Taliente +1
It is known that, for a range of chemical potentials, the infrared behavior of the complex Sachdev-Ye-Kitaev (cSYK) model is governed by a 1D Nearly Conformal Field Theory (NCFT$_{…
Scaling limits of complex Sachdev-Ye-Kitaev models and holographic geometry
Elena Gubankova, Subir Sachdev, Grigory Tarnopolsky
We compare different limits of the Sachdev-Ye-Kitaev model of complex fermion with -fermion interactions. First, we compute the fermion Green's function and free energy in t…
Yang-Lee Quantum Criticality in Various Dimensions
Erick Arguello Cruz, Igor R. Klebanov, Grigory Tarnopolsky +1
The Yang-Lee universality class arises when imaginary magnetic field is tuned to its critical value in the paramagnetic phase of the Ising model. In , this non-unitary C…
Towards a Quintic Ginzburg-Landau Description of the Minimal Model
Andrei Katsevich, Igor R. Klebanov, Zimo Sun +1
We discuss dimensional continuation of the massless scalar field theory with the interaction term. It preserves the so-called symmetry, which acts by $Ï\rig…
On the Entire Structure of the Energy Bands of 1D Moiré Superchain
Dmitrii Vorobev, Yiheng Chen, Grigory M. Tarnopolsky
We consider a general model of two atomic chains forming a moiré pattern due to a small mismatch in their lattice spacings, given by . Assuming arbitrar…
