Helical superfluid in a frustrated honeycomb Bose-Hubbard model
Tzu-Chi Hsieh, Han Ma, Leo Radzihovsky
We study a "helical" superfluid, a nonzero-momentum condensate in a frustrated bosonic model. At mean-field Bogoliubov level, such a novel state exhibits "smectic" fluctuation that…
Finite-temperature spectroscopy of dirty helical Luttinger liquids
Tzu-Chi Hsieh, Yang-Zhi Chou, Leo Radzihovsky
We develop a theory of finite-temperature momentum-resolved tunneling spectroscopy (MRTS) for disordered, interacting two-dimensional topological-insulator edges. The MRTS compleme…
Electrical valley filtering in transition metal dichalcogenides
Tzu-Chi Hsieh, Mei-Yin Chou, Yu-Shu Wu
This work investigates the feasibility of electrical valley filtering for holes in transition metal dichalcogenides. We look specifically into the scheme that utilizes a potential…
Emergence of Metallic Quantum Solid Phase in a Rydberg-Dressed Fermi Gases
Wei-Han Li, Tzu-Chi Hsieh, Chung-Yu Mou +1
We examine possible low-temperature phases of a repulsively Rydberg-dressed Fermi gas in a three-dimensional free space. It is shown that the collective density excitations develop…
