Kavli Affiliate: Tom Melia | First 5 Authors: Lukas Graf, Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama | Summary: We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation […]
Kavli Affiliate: Leon Balents | First 5 Authors: Kasra Hejazi, Zhu-Xi Luo, Leon Balents, , | Summary: We study untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, with in particular a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. A continuum low energy field theory is utilized to study such systems. We develop a phase […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, William S. Whitney, Meir Y. Grajower, Kenji Watanabe, Takashi Taniguchi | Summary: Black phosphorus (BP) offers considerable promise for infrared and visible photonics. Efficient tuning of the bandgap and higher subbands in BP by modulation of the Fermi level or application of vertical electric […]
