Exact Semiclassical Dynamics in a Multidimensional Quartic Potential: Multi-Flavor Instantons and Pre-Factor Dominance at Strong Coupling
Pervez Hoodbhoy, M. Haashir Ismail, M. Mufassir
We present an exact semi-classical analysis of a coupled multi-degree-of-freedom quantum system governed by a symmetric quartic potential with four degenerate minima. Starting from…
Coupled Instantons In A Four-Well Potential With Application To The Tunneling Of A Composite Particle
Pervez Hoodbhoy, M. Haashir Ismail, M. Mufassir
Coupled instantons are introduced by generalizing the double well potential to multiple mutually coupled wells. Physically this corresponds to the simultaneous tunneling of multipl…
Instability induced by exchange forces in a 2-D electron gas in a magnetic field with uniform gradient
Pervez Hoodbhoy
The exchange interaction is investigated theoretically for electrons confined to a 2-D sample placed in a linearly varying magnetic field perpendicular to the plane. Unusual and in…
Augmenting the Gauge-Gravity Correspondence to include Hadron Polarizabilities
Pervez Hoodbhoy
ADS/CFT models have achieved considerable success in describing hadronic properties such as masses and Regge trajectories. Even if the minimal vertex that couples photons to struct…
Quantum Tunneling Of Electron Snake States In An Inhomogeneous Magnetic Field
Pervez Hoodbhoy
In a two dimensional free electron gas (2DEG) subjected to a perpendicular spatially varying magnetic field, the classical paths of electrons are snake-like trajectories that weave…
ADS/CFT Applied To Vector Meson Emission From A Heavy Accelerated Nucleus
Pervez Hoodbhoy
We consider a classical source, moving on the 4-D boundary of a 5-D ADS space, that is coupled to quantum fields residing in the bulk. Bremsstrahlung-like radiation of the correspo…
