Valley-polarized Josephson Junctions as gate-tunable - qubit platforms
Zhong-Chang-Fei Li, Yu-Xuan Deng, Zi-Ting Sun +2
Recently, gate-defined Josephson junctions based on magic-angle twisted bilayer graphene (MATBG) have been fabricated. In such a junction, local electrostatic gating can create two…
Anomalous periodicity and Majorana zero modes in chiral Josephson junctions
Zi-Ting Sun, Jin-Xin Hu, Ying-Ming Xie +1
Recent experiments reported that quantum Hall chiral edge state-mediated Josephson junctions (chiral Josephson junctions) could exhibit Fraunhofer oscillations with a periodicity o…
Boundaries and Interfaces with Localized Cubic Interactions in the Model
Sabine Harribey, Igor R. Klebanov, Zimo Sun
We explore a new approach to boundaries and interfaces in the model where we add certain localized cubic interactions. These operators are nearly marginal when the bulk dime…
The Källén-Lehmann representation in de Sitter spacetime
Manuel Loparco, Joao Penedones, Kamran Salehi Vaziri +1
We study two-point functions of symmetric traceless local operators in the bulk of de Sitter spacetime. We derive the Källén-Lehmann spectral decomposition for any spin and show th…
Heesch Weyl Fermions in inadmissible chiral antiferromagnets
Xue-Jian Gao, Zi-Ting Sun, Ruo-Peng Yu +2
Symmetry is a crucial factor in determining the topological properties of materials. In nonmagnetic chiral crystals, the existence of the Kramers Weyl fermions reveals the topologi…
Hilbert space of Quantum Field Theory in de Sitter spacetime
Joao Penedones, Kamran Salehi Vaziri, Zimo Sun
We study the decomposition of the Hilbert space of quantum field theory in dimensional de Sitter spacetime into Unitary Irreducible Representations (UIRs) of its isometry g…
