Probing the Mott physics in kappa-(BEDT-TTF)(2)X salts via thermal expansion
(Iop Publishing Ltd, 2015-02-11)
In the field of interacting electron systems the Mott metal-to-insulator (MI) transition represents one of the pivotal issues. The role played by lattice degrees of freedom for the Mott MI transition and the Mott criticality ...

Mott-Anderson metal-insulator transitions from entanglement
(2021-10-01)
A metal can be driven to an insulating phase through distinct mechanisms. A possible way is via the Coulomb interaction, which then defines the Mott metal-insulator transition (MIT). Another possibility is the MIT driven ...
First-order insulator-to-metal Mott transition in the paramagnetic 3D system GaTa4Se8
(American Physical Society, 2014-08-22)
The nature of the Mott transition in the absence of any symmetry breaking remains a matter of debate. We study the correlation-driven insulator-to-metal transition in the prototypical 3D Mott system GaTa4Se8, as a function ...
How a dc Electric Field Drives Mott Insulators out of Equilibrium
(American Physical Society, 2018-07)
Out of equilibrium phenomena are a major issue of modern physics. In particular, correlated materials such as Mott insulators experience fascinating long-lived exotic states under a strong electric field. Yet, the origin ...
Non-thermal resistive switching in Mott insulator nanowires
(Springer, 2020-06)
Resistive switching can be achieved in a Mott insulator by applying current/voltage, which triggers an insulator-metal transition (IMT). This phenomenon is key for understanding IMT physics and developing novel memory ...
Diamagnetic currents supported by collective charge waves in a class of Mott insulators
(1995)
We put forward a model of tightly bound electrons in a bipartite lattice with repulsive interaction between electrons of same spin located in neighboring sites. Assuming external magnetic field the stationary states are ...
Dynamical self-stabilization of the Mott insulator: Time evolution of the density and entanglement entropy of out-of-equilibrium cold fermion gases
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETY, 2011)
The time evolution of the out-of-equilibrium Mott insulator is investigated numerically through calculations of space-time-resolved density and entropy profiles resulting from the release of a gas of ultracold fermionic ...
A Leaky-Integrate-and-Fire Neuron Analog Realized with a Mott Insulator
(Wiley VCH Verlag, 2017-03)
During the last half century, the tremendous development of computers based on von Neumann architecture has led to the revolution of the information technology. However, von Neumann computers are outperformed by the mammal ...
