Girardeau has shown that an exact analytical formula may be given for the ground‐state wave‐function of a system of one‐dimensional impenetrable bosons. Starting with this formula, we give a mathematically rigorous analysis leading to the determination of major features of the momentum distribution...

Viscosity of a kink in the one-dimensional φsystem is investigated. It is generated by momentum transfer between the kink and phonons. Mori's formula for the viscosity is calculated in a form of low temperature expansion, using the collective coordinate method, in which the kink location is ...

We show that the asymmetric inter-particle interactions can induce rapid decay of the heat current correlation in one-dimensional momentum conserving lattices. When the asymmetry degree is appropriate, even exponential decay may arise. This fact suggests that the power-law decay predicted by the hydro...

In a one-dimensional spin-1/2 chain, a particle-like excitation called a spinon is known to be responsible for spin fluctuation in a paramagnetic state. Spinons behave as a Tomonaga–Luttinger liquid at low energy, and the spin system is often called a quantum spin chain4. Here we show ...
Here, we derived the characteristic speeds and the choked flow condition from the full transient quasi-one-dimensional system of equations. Combining mass and momentum equations, and neglecting the inertial term ∂u∂t and lateral flow, conservation of momentum can be written as: (7)ρmixu∂...
