Exotic quantum spin liquid (QSL) is formed with such hypothetic particles as fermionic spinons carrying spin 1/2 and no charge. Here we calculate its thermodynamic and relaxation properties. Our calculations unveil the fundamental properties of QSL, forming strongly correlated Fermi system located at a fermion condensation quantum phase transition. These are in a good agreement with experimental data and allow us to detect the behavior of QSL as that observed in heavy fermion metals. We predict… 
Strongly correlated quantum spin liquid in herbertsmithite
Strongly correlated Fermi systems are among the most intriguing and fundamental systems in physics. We show that the herbertsmithite ZnCu3(OH)6Cl2 can be regarded as a new type of strongly correlated
Quantum Criticality of Spin Liquids in Novel Insulators and Magnets
Strongly correlated Fermi systems are among the most intriguing and fundamental systems in physics, whose realization in some compounds is still under consideration. Quantum spin liquids are a
Quantum Spin Liquid in Geometrically Frustrated Magnets and the New State of Matter
In this Chapter, we consider QSL formed by spinons that are chargeless fermionic quasiparticles with spin 1/2, filling up the Fermi sphere up to the Fermi momentum \(p_F\). The excitations of QSL are
Thermodynamic, Dynamic, and Transport Properties of Quantum Spin Liquid in Herbertsmithite from an Experimental and Theoretical Point of View
In our review, we focus on the quantum spin liquid (QSL), defining the thermodynamic, transport, and relaxation properties of geometrically frustrated magnet (insulators) represented by
Universal Behavior of Quantum Spin Liquid and Optical Conductivity in the Insulator Herbertsmithite
We analyze optical conductivity with the goal to demonstrate experimental manifestation of a new state of matter, the so-called fermion condensate. Fermion condensates are realized in quantum spin
Strongly Correlated Quantum Spin Liquids versus Heavy Fermion Metals: A Review
