The Schrödinger equation in the complex plane and quantum entanglement
Vassiliy Lubchenko
We formulate a continuity equation for the Schrödinger equation in the complex space. We define a complex momentum by normalizing the complex current by the particle density. This…
Temperature-driven narrowing of the insulating gap as a precursor of the insulator-to-metal transition: Implications for the electronic structure of solids
Vassiliy Lubchenko, Arkady Kurnosov
We present a microscopic picture rationalizing the surprisingly steep decrease of the band gap with temperature in insulators, crystalline or otherwise. The gap narrowing largely r…
Low-temperature anomalies in disordered solids: A cold case of contested relics?
Vassiliy Lubchenko
Amorphous solids manifest puzzling effects of mysterious degrees of freedom that give rise to a heat capacity and phonon scattering in great excess over what would be expected for…
A mechanism for reversible mesoscopic aggregation in liquid solutions
Ho Yin Chan, Vassiliy Lubchenko
We show systematically that a steady-state ensemble of mesoscopic inclusions of a solute-rich fluid can emerge in liquid solutions well outside the region of stability of the solut…
Aging, jamming, and the limits of stability of amorphous solids
Vassiliy Lubchenko, Peter G. Wolynes
Apart from not having crystallized, supercooled liquids can be considered as being properly equilibrated and thus can be described by a few thermodynamic control variables. In cont…
Structural origin of the midgap electronic states and the Urbach tail in pnictogen-chalcogenide glasses
Alexey Lukyanov, Jon C. Golden, Vassiliy Lubchenko
We determine the electronic density of states for computationally-generated bulk samples of amorphous chalcogenide alloys AsSe. The samples were generated using a s…
