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…
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…
Theory of the Structural Glass Transition: A Pedagogical Review
Vassiliy Lubchenko
The random first-order transition (RFOT) theory of the structural glass transition is reviewed in a pedagogical fashion. The rigidity that emerges in crystals and glassy liquids is…
Self-consistent elastic continuum theory of degenerate, equilibrium aperiodic solids
Dmytro Bevzenko, Vassiliy Lubchenko
We show that the vibrational response of a glassy liquid at finite frequencies can be described by continuum mechanics despite the vast degeneracy of the vibrational ground state;…
On the Mechanism of Activated Transport in Glassy Liquids
Vassiliy Lubchenko, Pyotr Rabochiy
We explore several potential issues that have been raised over the years regarding the "entropic droplet" scenario of activated transport in liquids, due to Wolynes and coworkers,…
Microscopically based calculations of the free energy barrier and dynamic length scale in supercooled liquids: The comparative role of configurational entropy and elasticity
Pyotr Rabochiy, Peter G. Wolynes, Vassiliy Lubchenko
We compute the temperature-dependent barrier for alpha-relaxations in several liquids, without adjustable parameters, using experimentally determined elastic, structural, and calor…
Electronic structure and the glass transition in pnictide and chalcogenide semiconductor alloys. Part II: The intrinsic electronic midgap states
Andriy Zhugayevych, Vassiliy Lubchenko
We propose a structural model that treats in a unified fashion both the atomic motions and electronic excitations in quenched melts of pnictide and chalcogenide semiconductors. In…
Electronic structure and the glass transition in pnictide and chalcogenide semiconductor alloys. Part I: The formation of the -network
Andriy Zhugayevych, Vassiliy Lubchenko
Semiconductor glasses exhibit many unique optical and electronic anomalies. We have put forth a semi-phenomenological scenario (J. Chem. Phys. 132, 044508 (2010)) in which several…
Stress distribution and the fragility of supercooled melts
Dmytro Bevzenko, Vassiliy Lubchenko
We formulate a minimal ansatz for local stress distribution in a solid that includes the possibility of strongly anharmonic short-length motions. We discover a broken-symmetry meta…
Charge and momentum transfer in supercooled melts: Why should their relaxation times differ?
Vassiliy Lubchenko
The steady state values of the viscosity and the intrinsic ionic-conductivity of quenched melts are computed, in terms of independently measurable quantities. The frequency depende…
Theory of Structural Glasses and Supercooled Liquids
Vassiliy Lubchenko, P. G. Wolynes
We review the Random First Order Transition Theory of the glass transition, emphasizing the experimental tests of the theory. Many distinct phenomena are quantitatively predicted o…
Electrodynamics of Amorphous Media at Low Temperatures
Vassiliy Lubchenko, Robert J. Silbey, Peter G. Wolynes
Amorphous solids exhibit intrinsic, local structural transitions, that give rise to the well known quantum-mechanical two-level systems at low temperatures. We explain the microsco…
The Microscopic Quantum Theory of Low Temperature Amorphous Solids
Vassiliy Lubchenko, Peter G. Wolynes
The quantum excitations in glasses have long presented a set of puzzles for condensed matter physicists. A common view is that they are largely disordered analogs of elementary exc…
Comment on the ``Novel Isotope Effects Observed in Polarization Echo Experiments in Glasses''
Vassiliy Lubchenko, Peter G. Wolynes
The novel isotope and magnetic effects on two level system echoes in glasses observed by Nagel et al.(Phys.Rev.Lett. 92, 245511 (2004)) provide unique experimental insight into the…
Barrier Softening near the onset of Non-Activated Transport in Supercooled Liquids: Implications for Establishing Detailed Connection between Thermodynamic and Kinetic Anomalies in Supercooled Liquids
Vassiliy Lubchenko, Peter G. Wolynes
According to the Random First Order Transition (RFOT) theory of glasses, the barriers for activated dynamics in supercooled liquids vanish as the temperature of a viscous liquid ap…
The Origin of the Boson Peak and the Thermal Conductivity Plateau in Low Temperature Glasses
Vassiliy Lubchenko, Peter G. Wolynes
We argue that the intrinsic glassy degrees of freedom in amorphous solids giving rise to the thermal conductivity plateau and the ``boson peak'' in the heat capacity at moderately…
