quantum Tricritical Point in the temperature pressure magnetic field phase diagram of cetige3
Physical Review B, 2018Co-Authors: Valentin Taufour, Udhara S Kaluarachchi, Sergey L Budko, Paul C CanfieldAbstract:We report the temperature-pressure-magnetic field phase diagram of the ferromagnetic Kondo-lattice CeTiGe$_3$ determined by means of electrical resistivity measurements. Measurements up to $\sim$ 5.8 GPa reveal a rich phase diagram with multiple phase transitions. At ambient pressure, CeTiGe$_3$ orders ferromagnetically at $T_\text{C}$ = 14 K. Application of pressure suppresses $T_\text{C}$, but a pressure induced ferromagnetic quantum criticality is avoided by the appearance of two new successive transitions for $p$ $>$ 4.1 GPa that are probably antiferromagnetic in nature. These two transitions are suppressed under pressure, with the lower temperature phase being fully suppressed above 5.3 GPa. The critical pressures for the presumed quantum phase transitions are $p_1$ $\cong$ 4.1 GPa and $p_2$ $\cong$ 5.3 GPa. Above 4.1 GPa, application of magnetic field shows a Tricritical Point evolving into a wing structure phase with a quantum Tricritical Point at 2.8 T at 5.4 GPa, where the first order antiferromagnetic-ferromagnetic transition changes into the second order antiferromagnetic-ferromagnetic transition.

Physical Review B, 2018Co-Authors: Valentin Taufour, Udhara S Kaluarachchi, Sergey L Budko, Paul C CanfieldAbstract:We report the temperature-pressure-magnetic-field phase diagram of the ferromagnetic Kondo-lattice ${\mathrm{CeTiGe}}_{3}$ determined by means of electrical resistivity measurements. Measurements up to $\ensuremath{\sim}5.8\phantom{\rule{0.16em}{0ex}}\mathrm{GPa}$ reveal a rich phase diagram with multiple phase transitions. At ambient pressure, ${\mathrm{CeTiGe}}_{3}$ orders ferromagnetically at ${T}_{\text{C}}=14$ K. Application of pressure suppresses ${T}_{\text{C}}$, but a pressure-induced ferromagnetic quantum criticality is avoided by the appearance of two new successive transitions for $pg4.1$ GPa that are probably antiferromagnetic in nature. These two transitions are suppressed under pressure, with the lower-temperature phase being fully suppressed above 5.3 GPa. The critical pressures for the presumed quantum phase transitions are ${p}_{1}\ensuremath{\cong}4.1$ GPa and ${p}_{2}\ensuremath{\cong}5.3$ GPa. Above 4.1 GPa, application of magnetic field shows a Tricritical Point evolving into a wing-structure phase with a quantum Tricritical Point at 2.8 T at 5.4 GPa, where the first-order antiferromagnetic-ferromagnetic transition changes into the second-order antiferromagnetic-ferromagnetic transition.

constraints on the merging of the transition lines at the Tricritical Point in a wing structure phase diagram
Physical Review B, 2016Co-Authors: Valentin Taufour, Udhara S Kaluarachchi, V G KoganAbstract:Author(s): Taufour, V; Kaluarachchi, US; Kogan, VG | Abstract: We consider the phase diagram of a ferromagnetic system driven to a quantum phase transition with a tuning parameter p. Before being suppressed, the transition becomes of the first order at a Tricritical Point, from which wings emerge under application of the magnetic field H in the T-p-H phase diagram. We show that the edge of the wings merge with tangent slopes at the Tricritical Point.

Tricritical Point and solid liquid gas phase transition of higher dimensional ads black hole in massive gravity
Annals of Physics, 2020Co-Authors: Bo Liu, Zhanying Yang, Ruihong YueAbstract:Abstract By considering the fifth order graviton term in massive gravity theory, we study the P – V critical behaviors of AdS black hole in d ≥ 7 dimensional space–time, and find the solid/liquid/gas phase transition with the “common” Tricritical Point, which does not exist in absence of higher graviton terms. Moreover, we also find the number of positive real roots of critical radius equation plays a key role in classifying different kinds of phase transitions. If there is only one positive root of equation, the first order Van der Waals-like phase transition emerges. For two roots, the system could experience a zero-order reentrant phase transition. Notably, for three roots, the solid/liquid/gas phase transition can occur. In addition, because the critical radius equation is a ( n − 2 )-order polynomial equation associated with the graviton terms, the critical phenomena of black holes in extended phase space depend crucially on the number n of the graviton terms in high dimensional massive gravity.

Tricritical Point and solid liquid gas phase transition of higher dimensional ads black hole in massive gravity
arXiv: High Energy Physics - Theory, 2018Co-Authors: Bo Liu, Zhanying Yang, Ruihong YueAbstract:By considering the fifth order term of the interaction potential in massive gravity theory, we study the $P-V$ critical behaviors of AdS black hole in $d \geq 7$ dimensional space-time, and find the Tricritical Point and the solid/liquid/gas phase transition in addition to the Van der Waals-like phase and the reentrant phase transition of the system. The critical phenomena of black holes depend crucially on the number $n$ of interaction potential terms.
