Local wave-packet spectroscopy of the Drude weight in Tomonaga-Luttinger liquids

Takayuki Yokoyama, Yasuhiro Tada

We investigate wave packets generated by a local pulse electric field in a Tomonaga-Luttinger liquid (TLL) with a U(1) charge . Bosonization shows that a local pulse field creat…

Diagnosing energy gap in quantum spin liquids via polarization amplitude

Takayuki Yokoyama, Yasuhiro Tada

Identifying whether a many-body ground state is gapped or gapless is a fundamental yet challenging problem, especially in quantum spin liquids. In this work, we develop a gap-diagn…
