2D Helical Twist Controls Tricritical Point in an Interacting Majorana Chain
Hekai Zhao, Philip Phillips
We analyze a series of interacting Majorana Fermion chains with finite range pair interactions with coupling strength that all exhibit a tri-critical point that separates an Is…

Proof that Momentum Mixing Hatsugai Kohmoto equals the Twisted Hubbard Model
Yuting Bai, Philip W. Phillips
We prove formally that the momentum-mixing Hatsugai-Kohmoto model (MMHK) is the Hubbard model with a twist. With this result in tow, we rely on the proof of Watanabe's that two mod…
