Improved stability for 2D attractive Bose gases

This implies, using previous results, that the many-body ground states and dynamics converge to the NLS ones for an extended range of diluteness parameters. Expand abstract.

Entanglement Hamiltonian of Many-body Dynamics in Strongly-correlated Systems

These findings not only provide crucial information on how equilibrium statistical mechanics emerges in many-body dynamics, but also add a tool to exploring quantum dynamics from perspective of entanglement Hamiltonian. Expand abstract.

Optimal Selection of Structural Degree of Freedoms for Spceial Microscopic States to Characterize Disordered Structures

Despite this fact, our recent study reveals that a single (and a few additional) microscopic state (called projection state: PS), whose structure can be known a priori without r equiring thermodynamic information, can universally characterize equiibrium properties for disordered states, where their sturctures depends on configurational geometry before...

Many-body localization in the two dimensional Bose-Hubbard model

For any considered (local) interaction we find a mobility edge that terminates at sufficiently large disorder strength, implying the existence of a many-body localized phase. Expand abstract.

Quantum noise in carbon nanotubes as a probe of correlations in the Kondo regime

Most of the time, electronic excitations in mesoscopic conductors are well described, around equilibrium, by non-interacting Landau quasi-particles. Expand abstract.

Multifractality and its role in anomalous transport in the disordered XXZ spin-chain

Moreover it is not clear if similarly to the case of single-particle physics, multifractal properties of the many-body eigenstates are related to anomalous transport, which is observed in this model. Expand abstract.

The charge-dependent Bonn potentials with pseudovector pion-nucleon coupling

To apply the high-precision realistic nucleon-nucleon ($NN$) potentials on the investigations of relativistic many-body methods, the new versions of charge-dependent Bonn (CD-Bonn) $NN$ potential are constructed within the pseudovector pion-nucleon coupling instead of the pseudoscalar type in the original CD-Bonn potential worked out by Machleidt [Phys.

Experimental extraction of the quantum effective action for a non-equilibrium many-body system

On the fundamental level, quantum fluctuations or entanglement lead to novel forms of complex dynamical behaviour in many-body systems for which a description as emergent phenomena can be found within the framework of quantum field theory. Expand abstract.

Semi-localization transition driven by a single asymmetrical tunneling

We investigate the many-body ground state property of a one-dimensional tight-binding ring with an embedded single asymmetrical dimer based on exact solutions. Expand abstract.
