Coherent-incoherent transition in the sub-Ohmic spin-boson model
Alex Chin, Misha Turlakov
We study the spin-boson model with a sub-Ohmic bath using a variational method. The transition from coherent dynamics to incoherent tunneling is found to be abrupt as a function of…
Effective charging energy for a regular granular metal array
Y. L. Loh, V. Tripathi, M. Turlakov
We study the Ambegaokar-Eckern-Schön (AES) model for a regular array of metallic grains coupled by tunnel junctions of conductance and calculate both paramagnetic and diamagnet…
Quantum phase transitions of magnetic rotons
Joerg Schmalian, Misha Turlakov, ;
Due to weak spin-orbit coupling, the magnetic excitations of an itinerant ferromagnet become magnetic rotons, excitations with degenerate minima on a hypersphere at finite wavevect…
Universal sound absorption in low-temperature glasses
Misha Turlakov
Phenomenologically assuming a sharp decrease of shear relaxation time for large wavevector density modes (where is of order of inverse of several interatomic distance…
Coulomb blockade and quantum tunnelling in the low-conductivity phase of granular metals
V. Tripathi, M. Turlakov, Y. L. Loh
We study the effects of Coulomb interaction and inter-grain quantum tunnelling in an array of metallic grains using the phase-functional approach for temperatures well below th…
Sum rule analysis of Umklapp processes and Coulomb energy: application to cuprate superconductivity
Misha Turlakov, Anthony J. Leggett
The third moment frequency sum rule for the density-density correlation function is rederived in the presence of Umklapp processes. Upper and lower bounds on the electron-electron…
